Title:Variable Surface Roughness Transition and Turbulence Modeling for Rotor Parasitic Drag
Abstract:Intelligent Automation, Inc. (IAI), in collaboration with the Alfred Gessow Rotorcraft Center at the University of Maryland (UMD) at College Park, submits this Phase I Army SBIR to develop a numerical model for variable surface roughness distributions of materials such as glass, metal, and protective coatings that can be used in CFD simulations for accurate estimation of the parasite drag of an aircraft. The end product will be a surface roughness model based on efficient engineering algorithms that can be implemented into government and industry production-level CFD codes to estimate parasite drag of an Army aircraft within its design envelope.

Title:Engineering Formulations for Turbulence Modeling of Variable Surface Roughness Effects in Wall-Bounded Flows
Abstract:The proposed effort has the objective to develop a method for representing the influence of surface roughness on turbulent transport. The method is designed for highly non- equilibrium flows, as occurs on helicopter rotors, and in other engineering applications. It is based on the displacement of origin approach, which is a way to incorporate roughness into Reynolds-averaged Navier-Stokes (RANS) turbulence models via modified boundary conditions: it is our objective to devise an approach that is useable with standard engineering meshes and CFD methods. Further, the methodology also contains a formulation for intermittency, suitable for rough-wall boundary layers, to blend between laminar and fully turbulent states. The model will be validated against experimental data for abruptly changing surface roughness. Additional experiments will be conducted under this SBIR Phase I program to address the type of roughness that is found on rotors operated in harsh environments, and with protective coatings. While the acquired data is directly relevant to this application, it will also be of fundamental, benchmark type.

Title:Enhanced Carbon Face Seals for Rotorcraft Drive Systems
Abstract:Seals currently used for rotorcraft gearbox drive systems suffer from a high failure rate. Seals must prevent lubricant from escaping while under operation. Several materials are available for the seals, including carbon, elastomer, and ceramic, and all must withstand extreme shaft speeds (5,000-13,000 RPM) and temperatures (500 °F). Carbon face seals, which are predominantly used in rotorcraft either individually or in a magnetic seal assembly, can exhibit short lifetimes due to a variety of factors including debris entrapment at the seal interface, oxidation associated with incompatible lubricating oils and/or contaminants, and misalignment during installation. The time and manpower required to identify seal failures and replace seals is extremely costly and reduces fleet availability. Luna Innovations proposes an enhanced carbon face seal that will enhance seal lifetime and reliability. Modifications to the seal material chemistry and morphology will lead to higher durability and lower failure rate at comparable performance. The solution will be based significantly on previous experience with high performance carbon composites. The Phase I will involve proof-of-concept demonstration through material fabrication, optimization, testing, and collaboration with existing material suppliers, seal assembly manufacturers, and prime contractors.

Title:Advanced Seal Technology for Helicopter Drive System Application
Abstract:Gearbox seal wear and leakage is a major source of maintenance and downtime for rotorcraft. Sentient will use our advanced tribology modeling technology to evaluate coatings and surface texturing processes for carbon face seals and provide a generalized modeling approach that can replace physical testing of seals. These models will be used to evaluate several rotorcraft seal designs proposed by our industry partner University of Akron to determine the real performance, durability and cost-benefit. During the project, these models will be validated with physical testing, resulting in advanced seal technology that is backed up by simulation and testing. Current seals are designed, manufactured and tested before fielding. Problems that arise in fielding often take years to manifest, meaning that retrofits and repairs are costly. Instead, Sentient will simulate the lifetime performance and durability of seals before manufacturing, thus reducing or eliminating problems that will arise later, leading to reduced maintenance cost and aircraft downtime.

Title:Selective Ammunition Feed System
Abstract:To address the Army’s need for a compact, lightweight, high-rate, selective ammunition feed system for machine guns and auto cannons, Physical Optics Corporation (POC) proposes to develop a new Selective Ammunition Feed System (SAFS). SAFS combines the use of robust ammunition identification using existing ammo color coding, mature ammunition handling systems, and control electronics. This novel design will enable the SAFS to accurately and rapidly select the designated ammunition types and loaded them onto the aircraft’s ammo carriers. As a result, SAFS offers high-speed selection of five or more ammo types, real-time ammo inventory, health monitoring, weighs or = 2 to demonstrate the SAFS feasibility. In Phase II, we will continue the design of SAFS and fabricate a TRL > or = 4 prototype to demonstrate its key capabilities in a benchtop environment by using M848 dummy rounds painted with appropriate color-code bands to simulate other types of M230 ammo.

Title:SmartMAG - Automated Self-Indexing Magazine and Rapid Selective Deployment System
Abstract:Future weapon system operators of attack vehicles will use advanced ammunition technology as a battlefield force multiplier providing improved lethality and tactical superiority against the enemy. This will be accomplished by employing a suite of tactical, "Smart" rounds with varying capabilities to carry out defeat of the enemy. The use of Smart rounds will result in the soldier's spending less time engaged in costly and potentially deadly fire exchanges with enemy forces. The last barrier to achieving this critical tactical integration is a "Smart-Feed" magazine and deployment system to first locate the system-selected round in a magazine, and then rapidly deploy the selected smart round to the feeder at the gun turret. SMRC proposes the SmartMAG, an automated self-indexing magazine and rapid selective deployment mechanism. With the press of a button in the cockpit, the SmartMAG locates the selected round, transfers the round to the linkless feed system, then rapidly deploys the round to the feeder at the gun turret - all within seconds. The SmartMAG system will consist of an Ammunition Control Unit coupled with a Red-Green-Blue color sensor, a standard magazine storage unit, and a sprocket transfer assembly based on the current magazine technology available.

Title:Low Cost Cockpit head tracking and gestural recognition
Abstract:This proposal offers a solution for the development of a revolutionary new, low-cost, human machine interface for aviators. In this endeavor, Kutta and its partners design and develop an innovative concept that leverages commercial off the shelf (COTS) hardware and software. The well-structured applied research Work Plan overcomes some of the known issues with the Kinect and other COTS gaming technology for gesture recognition and head tracking with an equally innovative solution that leverages nano-technology. The resulting research yields an optimized product that takes advantage of as much COTS technology as possible to drive cost out of the resulting product. The product is a ubiquitous controller that can be utilized by pilots in the air, soldiers on the ground, and drivers in their automobiles to interact with machines through innovative gestures and head tracking technology. The Phase I work culminates in a demonstration of the product in a simulated cockpit and summary of the lessons learned through actual quantitative applied research. The Phase I option concludes with recommended methodologies and action plans on how to design, develop, test, and ruggedize the technology for transition into the Department of Defense aviation community.

Title:Low Cost Cockpit head tracking and gestural recognition
Abstract:Army pilots are presented with a wide variety of information from head down displays and sensor pods, and need to steer weapons and sensors based on head position. Current tracker systems are very expensive. New low cost head mounted displays (HMDs) require a low cost tracker. For all cockpits (and in the cargo/crew area) it would be very beneficial to have a way to sense gestures by pilots and crew members. This gestural control can aid the pilot, for example, by allowing them to control displays (panning, zooming and display selection) by using gestures while leaving their hands on, or near the controls. For crewmembers, a gesture recognition system can aid communications that are hard to do in a noisy environment, like the signaling between the loadmaster and the pilot in a heavy-lift helicopter. A low-cost head tracking and gesture recognition system would dramatically improve the interaction between pilots, crewman and the rotorcraft. Companies like Microsoft and ASUS have invested significantly in developing body and gesture tracking systems for Natural User Interfaces (NUIs). Leveraging this investment, SA Photonics proposes modifying an existing commercial tracking system for use in a rotorcraft cockpit and crew area.

Title:ASP Motion Base for Stabilized Mounts
Abstract:Several military helicopters feature forward firing weapons, which have simple and reliable mounts, but require the pilot to precisely point the aircraft at an intended target. Depending on the combat environment, this can place a significant burden on the pilots and often results in lowered aiming accuracy and increased potential for collateral damage. There are existing technologies that have been proven to operate well for precision weapon pointing, but these gimbal systems are prohibitively heavy for forward firing weapon applications. As such, Techno-Sciences, Inc., in collaboration with the University of Maryland, proposes to develop a technology with small-deflection precision pointing and adaptive recoil capabilities to increase the precision of forward firing weapons. The pointing accuracy will be achieved with pneumatic artificial muscle actuators and the adaptive recoil will be achieved with magnetorheological fluid dampers. Building upon our extensive experience and related patent portfolio, we will perform analyses and detailed design work in Phase I of the project. Phase II will be focused on further refinements and integration into functional hardware capable of demonstrations.

Title:Compact, Inexpensive, Microchannel Recuperators for Small Gas Turbines
Abstract:Small manned and unmanned aircraft need advanced propulsion technology to increase mission capabilities and improve reliability. We propose to develop an innovative recuperator technology that can significantly reduce fuel consumption for small gas turbines. Our microchannel recuperators are built using advanced manufacturing techniques that will enable a compact, inexpensive recuperator to significantly improve the performance of gas turbines and enable them to replace internal combustion engines in small aircraft. In Phase I we will work with a major supplier of UAVs to select the optimum application for the recuperated gas turbine. We will prove the feasibility of our approach by designing the recuperator, demonstrating the proposed fabrication approach, and analyzing flow, heat transfer, and structural integrity of the recuperator. We will assess the key design trade-offs, optimize the design, and estimate the manufacturing costs. In subsequent phases we will build prototype recuperators and demonstrate their performance in the laboratory and integrated with a gas turbine engine.

Title:Lightweight Recuperators for Small Turbine Engines
Abstract:Turbine engines can significantly reduce fuel consumption by using a recuperator to heat compressor discharge air with heat from combustion exhaust gases. This increased fuel efficiency is offset by the weight and pressure losses added by the recuperator, so these must be minimized, especially for small turbine engines. An extremely compact recuperator was previously built for the Rolls Royce Model 250-20B small turbine engine; in testing, this recuperator achieved a 70% effectiveness with hot- and cold-side pressure loss/pressure ratios of 3% at a core weight of less than 38 lbs. In the proposed effort this work will be extended to a higher power version of the Model 250 series, with a significant reduction in core weight/dissipated power via improved modeling, incorporation of lightweight materials, and improved core designs.

Title:Analysis Tools for Composite Laminate Material Properties Prediction
Abstract:A composite software design tool kit is proposed to predict composite properties using micro-mechanics augmented lamination theory. The capability will overcome shortcomings of progressive failure models and will take into account translaminar and interlaminar failure mechanisms. Starting from lamina properties, strength will be predicted for laminates subjected to tension and compression loading. Generation of allowables using scatter in fiber and matrix material properties and fabrication defects will be carried out by use of probabilistic methods to avoid the testing of large amounts of specimens before there is adequate confidence in the material properties. Integration with finite element approach will be accomplished by synthesis of telescoping composite mechanics from fiber and matrix constituents to laminate level. A significant innovation will be the accounting for damage/micro-crack induced anisotropy of the composite matrix properties. Methods to characterize the material properties under strain rate effects will be included. A commercial composite material characterization software MCQ will be enhanced and integrated into commercial (explicit/implicit) FEM codes for structural scale-up. The capability will consider effect of defects (void shape, size, distribution, and fiber waviness) and will rely on a physics-based micro-mechanics approach to reverse-engineer effective fiber/matrix constituent properties using five ASTM ply in-plane tests as input.

Title:Analysis Tools for Composite Laminate Material Properties Prediction
Abstract:ATA Engineering, Inc. proposes to advance the current state-of-the-art composite analysis techniques to predict laminate properties from limited ply-level material property data with an innovative approach to composite failure analysis. The Phase I effort will develop a stochastic approach to address strength-parameter variability, combined with a three-dimensional progressive failure model to properly capture out-of-plane strength and stiffness parameters. Along with variations in the material, environmental, and manufacturing variables, three- dimensional spatial variations will be introduced to accommodate variations in properties throughout a composite structure. The proposed progressive failure model will consider improved material property degradation models that better represent the physics during failure. Finally, advanced statistical sampling techniques will be employed to improve computational efficiency as compared to traditional random sampling methods.

Title:Residual Property Prediction for Damage Composite Structures
Abstract:During a component’s service life, damage due to high or low energy impact may be introduced, which may lead to premature failure of these structures. Component level structural testing and analysis of advanced composites is prohibitively expensive and time consuming. Instead, using robust and accurate computational tools complemented by experiments at key stages is a viable and cost-effective option. Currently, there is no analysis capability that can predict all possible failure modes concerning advanced composites because damage initiation and its progressive growth is very complex, and that commonly accepted methods, such as finite element method or smoothed-particle hydrodynamics, break down. However, damage prediction in peridynamic theory (PD) is more realistic than the methods utilizing the classical continuum theory since the PD considers material failure as a part of the material response without resorting to any external damage criterion. Therefore, the PD appears to be the best candidate for damage assessment in advanced composite structures. The goal of this proposed project is to develop a methodology for accurate prediction of damage due to blast and penetration events as well as low-energy impacts, and determination of the residual strength resulting from these events on advanced composite structures and components.

Title:Residual Property Prediction for Damaged Composite Structures (MSC P 4091)
Abstract:Advanced composite material systems are vital to the development of lightweight, multi- functional Army missile systems. In addition to reducing the weight of the structure, these material systems provide the ability to expand the function of the structure by tailoring stiffness and strength characteristics for numerous applications. Carbon fiber-reinforced epoxy structures have become very attractive for applications such as solid rocket motor cases, missile airframes, missile guidance housings, as well as many launch tubes and launcher primary structures. The Weapons Development and Integration Directorate within AMRDEC have identified a need to understand the operational fitness of these types of structures following impact events for a wide range of energy levels. The overall objective of the proposed Phase I research program is to develop an analysis tool that allows designers to evaluate post impact residual strength of composite structures. A user element (UEL) subroutine for use with commercially available analysis codes, in particular an improved shell element that offers advantages in both the economy and reliability of computations, is proposed. This novel approach will link the UEL subroutine to a nonlinear material model to evaluate progressive damage of composite materials and a shear correction model that accurately predicts the transverse response of impacted composite structures.

Title:Residual Property Prediction for Damage Composite Structures
Abstract:To address the U.S. Armys need to predict the residual strength of composite material laminates that have suffered impacts, Texas Research Institute Austin (TRI/Austin) will integrate a set of new failure criteria into composite material laminate analysis programs that model the damage created by low and high velocity impacts. The failure analysis criteria will be based on properties from limited lamina mechanical tests. The Phase I effort will demonstrate that the new failure criteria can successfully predict the residual strength of laminated plates that have been impacted. For low velocity impacts, the algorithm proposed in the Phase I effort will analytically predict the total delamination area on the specimen for a given impactor geometry, weight, and lamination sequence of the composite. The analysis process can be integrated in spreadsheets or finite element programs. These analysis programs will make the use of composite materials less expensive because the design effort will be reduced, a lower level of testing will be required, and designs will be more efficient - thereby reducing deployment costs. The algorithm developed in the proposed effort will allow a go/no go decision with respect to the suitability of an impacted laminated composite material plate.

Title:Innovative Semi-Active Laser (SAL) Signal Processing Techniques in Noisy Environments
Abstract:This effort will focus on developing new SAL signal processing approaches and algorithms for pulse discrimination in dirty battlefields and active EOCM environments. This will be accomplished by identifying specific candidate approaches and algorithms, and evaluating them to select the most promising. Subsequent phases of this effort will design and prototype the selected algorithms and demonstrating their performance in the Armys Automated Laser Seeker Performance Evaluation System (ALSPES). Most existing US systems, notably the HELLFIRE missile, were developed in the 1970s and 1980s and were limited by technology available at that time. Those limitations determined approaches that were possible with regard to performance in dirty-battlefield environments and in dealing with active electro-optical countermeasures (EOCM). Recent changes in hardware to replace obsolete parts have significantly increased the processing capability of the HELLFIRE laser seeker and guidance unit, and new systems being developed are being designed from the beginning using the greatly-increased digital processing capability presently available. The possible improvements that GRA proposes to explore under this task are in areas such as: Adaptive Discrimination, Multi-Gate Discrimination, Improved Spot-Jump Algorithm, Improved Backscatter Rejection, Improved Resistance to Saturation or Overload of the Pulse Processing, and Improved Rejection of EOCM Pulses.

Title:Rapid Scene Creation for Multispectral Terrain Signature Models and Simulations
Abstract:JRM and DVC propose significant innovations around our powerful OSCRE architecture for rapid scene generation directly from raw terrain source data. OSCRE requires: high- resolution DEM data input, complete shape file/vector maps, and high-resolution satellite imagery. With these inputs, OSCRE supports OTF terrain tessellation/creation, 3D feature extrusion and model instantiation, material classification/physical property attribution, and credible physics-based multi-spectral sensor image generation. OSCRE applies physics- based irradiance, reflection, thermal, and atmospherics models to provide accurate, multispectral sensor simulation while rendering in real-time. OSCRE performs this entire process On-The-Fly, from loading the raw source data to producing high-fidelity, high dynamic range multispectral sensor imagery. This SBIR effort expands OSCRE’s architecture and develops innovative new algorithms to address cases where NGA and other terrain data-sources have “gaps”, like incomplete, low-resolution, or non-existent vector, feature, and elevation data. Such innovations will include fast photogrammetric algorithms for high-resolution DEM generation from stereo-pair imagery and/or Lidar/Ladar data; advanced, fast algorithms for feature extraction; rapid shape/vector-file generation; and advanced fast color-space clustering and PCA algorithms for image segmentation and material classification. The Phase I design and Phase II prototype will include a mechanism to generate rapid terrain/scene database output compatible with CSG and other multi- spectral sensor image rendering engines.

Title:Rapid Scene Creation for Multispectral Terrain Signature Models and Simulations
Abstract:The Army as well as other branches of the Department of Defense (DoD) have made a substantial investment in synthetic scene generation for the development and testing of sensor and weapon systems. The synthetic scenes have been developed for programs concerning: 1) missile system and unmanned aerial vehicles (UAV) sensor system performance assessment; 2) pre-flight predictions to identify or correct issues prior to field testing; and 3) soldier training systems. The specific goal of our Phase I SBIR proposal is to begin a program of work that applies our specific expertise in high fidelity synthetic scene generation toward the design, development, and demonstration of a new system process and software tools for rapidly developing real world background databases that will be compatible with current and future Army simulation scene generation codes. These scene databases include high resolution terrain classification and topography maps, natural and manmade clutter discrete models, and a mapping of the location, size, and orientation of each discrete in the scene. In the Phase I effort we will deliver a comprehensive road map, algorithmic solutions, preliminary demonstration software modules, and scene construction performance metrics required for the dramatically reducing the time needed to create simulation scene databases.

Title:Rapid Scene Creation for Multispectral Terrain Signature Models and Simulations
Abstract:Torch proposes the development of an efficient, high fidelity approach for the development of terrain models suitable for use in high fidelity electro-optical and infrared scene rendering applications and simulations. Torch will decrease developmental complexity and timelines through the development of characterization, artifact rectification, discrete and scene element development algorithms to achieve the efficient development of ground plane models, clutter classification models, models of discrete elements. Development will be in a two- fold manner. First, a Taylor series approach to algorithm development will be employed whereby most significant contributions are modeled with the greatest fidelity, while elements of lesser import receive less attention. Second, the algorithms will be developed for highly parallel execution in order to exploit implementation on modern computational hardware. This approach integrates directly with source data providers, directly into current thermal simulations and scene generators, while providing a path for increased fidelity and capability in these tools.

Title:Flexible, Compact Acoustic Transducer Arrays
Abstract:The main limitations in the use of conventional sensor arrays for acoustic reconnaissance are its required size and its rigid structure. In order to overcome these limitations without compromising the array sensitivity, it is of crucial importance to develop new concepts and techniques allowing sound concentration in small areas, directivity values beyond the conventional limits related to the total array size, and a flexible configuration. The broad class of acoustic metamaterials (MMs) appears to be the perfect candidate to solve these problems. In this proposal, we pursue two approaches to obtain flexible, compact acoustic sensor arrays: 1) improve current transducers with the introduction of MM elements and 2) design innovative classes of acoustic MM sensor arrays with increased angular sensitivity. We investigate the possibility to realize ultrasensitive arrays of transducers by broadband funneling of acoustic waves using broadband MMs for nonresonant matching of acoustic waves and acoustic zero-density MM channels for funneling and large phase control. We also study MM ultracompact transducers with superdirective properties, bio-inspired nonlinear acoustic transducers and acoustic superresolving transducer arrays.

Title:Flexible, Compact Acoustic Transducer Arrays
Abstract:The conventional approaches to acoustic arrays limit their usage in acoustic reconnaissance for Army applications due to large size and rigid packaging. An acoustic array on a flexible substrate and composed of microfabricated sensors provides a solution for applications where limited size and non-planar surfaces have prevented use of array-based solutions. The primary objective of this research is to develop microelectromechanical systems (MEMS)- based array technology for use in a flexible, conformal, compact acoustic array. Our proposed approach is to leverage recent advances in piezoelectric MEMS microphones, hybrid packaged with low-noise instrumentation amplifiers, mounted onto a flexible, conformal substrate and protected by a metamaterial-enhanced, flexible cover. The stated program goals necessitate an extensive feasibility study of the individual components to determine current readiness level, expectations for future performance and satisfaction of platform and system constraints.

Title:Sensitive and Diagnostic Mental Workload Classifier
Abstract:We propose to develop a sensitive and selective workload classifier, called PHYSIOPRINT (Physiology and Performance Research Integration Tool), that will ultimately operate in real time on multiple physiological signals (EEG, EKG, EOG, EMG) acquired and processed by our wearable and wireless X24 system. The raw signals will be converted into input variables for the classifier using a suite of proprietary real-time algorithms that include noise reduction, spectral decomposition and topographic mapping of the EEG signals, extraction of event-related potentials, detection of eye blinks and fixations, calculation of heart rate and heart rate variability, detection of EMG bursts and tonic activity, calculation of respiratory rate and detection of the head/body position and movements. PHYSIOPRINT will be designed around the IMPRINT model of mental workload and will discriminate between seven workload types (visual, auditory, cognitive, speech, tactile, fine and gross motor). PHYSIOPRINT will also provide a measure of overall workload construed to account for potential conflicts between different types of workload. Phase I research, which will include analysis of a large database of physiological data acquired during military-relevant tasks and a pilot study in a driving simulator, will define the PHYSIOPRINT design concept and development approach for Phase II.

Title:SMOLT: Sensitive Mental Workload Assessment Enhanced with Multi-Task Learning
Abstract:Mental workload is considered one of the most important contributors to human performance. In previous decades, considerable research has been conducted on workload assessment using different methods, such as subjective measurement and performance measurement. Recently, there is a trend to utilize physiological parameters, such as Electroencephalography (EEG) and Electrocardiography (ECG), for automatic objective workload assessment. Although significant progress has been made on physiological parameter based workload assessment, there are still a number of challenges to be addressed for automated workload assessment, two of which are: workload assessment in multiple dimensions (such as visual and cognitive) and high performance assessment. In this research, we propose a SMOLT software tool (sensitive mental workload enhanced with multi-task learning) for multidimensional workload assessment. SMOLT is innovative to build a multi-dimensional workload assessment model by incorporating advanced Multi-Task Learning (MTL) theory and multimodal deep learning, which is unique to model the relatedness among the output tasks (workload in different dimensions) and among input signals (multimodal deep learning for better feature representations). The proposed SMOLT is built on a significant amount of researches by our team to cognitive state assessment. We will incorporate the existing algorithms into SMOLT software and enhance the workload assessment in multi-dimensions.

Title:Alternative Source for Neutron Generation
Abstract:Phoenix Nuclear Labs (PNL) will perform a comprehensive analysis of all existing and proposed neutron generator technologies that do not utilize highly enriched fissile material. These technologies include the flux compression generator, dense plasma focus, high current deuterium-tritium fusion, and high current electrons incident upon uranium-238. Other technologies will also be identified and evaluated. The best technology will be selected based on its ability to meet the neutron and gamma flux requirements specified by the Army for nuclear survivability testing, and its cost, reliability, regulatory, operational, and security requirements. A conceptual prototype design will be produced in Phase I, and the system will be built and tested at PNL during Phase II. The prototype device will go to WSMR and will produce a burst flux of 6.5x10^13 n/cm^2 during a time scale of microseconds. It will also have a steady state operational mode equivalent to 8 kW operation of the WSMR FBR. The prototype device will not utilize highly enriched fissile material and will greatly reduce the cost and security burden to the Army for nuclear survivability testing. It is anticipated that a functional prototype can be delivered to the Army by the end of 2015.

Title:Alternative Source for Neutron Generation
Abstract:This Small Business Innovative Research Phase 1 proposal requests $100,000 support for TechSource to identify and document feasible technology options to replace the White Sands Fast Burst Reactor (FBR); reference Army Topic Number A12-088, Alternative Source for Neutron Generation. The U.S. Army requires a neutron generator to replace the FBR highly enriched uranium (HEU) based technology with a Low Enriched Uranium (LEU) technology that produces a radiation environment for nuclear survivability testing while reducing life-cycle costs, and increasing reliability and availability requirements. There is no obvious, low risk, economical approach to a HEU to LEU transition. TechSource will analyze the extensive body of knowledge in this area. We then will apply innovations to existing technologies and extend national lab research of critical experiments facilities, conversion of HEU reactors to LEU reactors, and application of accelerator technologies to enhance neutron environments. Our principal investigator (Ms. Charlene Cappiello) has recent, relevant, and firsthand knowledge and experience in radiation testing and experimentation environments. Our subject matter experts also have the firsthand, related science and technology knowledge experience needed to efficiently produce the most comprehensive analysis of what is feasible and provide the data for the required program and business case decision.

Title:Free-Space Optical Communications: Light Detection and Ranging Enhanced Data Delivery
Abstract:Airborne lidar has proven to be a highly valuable asset for gathering high quality geospatial intelligence information. Advanced lidar systems collect and process full waveform returns for each emitted laser pulse. Full lidar waveform data can be exploited to see through obscurants (e.g. dust, clouds, rain, snow, fog, and smoke), foliage, ocean water, etc, which enables systems to map areas under degraded visual environments; detects objects and land features under forested areas or camouflage; or detect mines and other object under sea water. These systems generate extreme volume of data that is traditionally stored, post processed, and later distributed through a processing exploitation dissemination (PED) chain. This process can take days to weeks to deliver to the warfighter, which limits its usefulness for tactical operations. A potential solution to improving the PED timeline is to utilize the on-board lidar transceiver as a high bandwidth free-space optical communications link to transmit the data to a remote ground station receiver. Aret Associates and LGS Innovations have partnered on this program to develop and demonstrate a Co-use Lidar Optical Communication System (CLOCS) designed to operate within the current Army framework of unmanned aerial systems (UAS). Aret Associates and LGS Innovations are best-in-class providers of advanced airborne lidar and free-space optical communications, respectively. Aret and LGS will leverage decades of development and > $100M CRAD investment to demonstrate full system performance by the end of Phase-II.

Title:Dual-Mode Continuous-Wave Ladar and Optical Communications System
Abstract:Because the data products generated by modern imaging ladar systems are inherently large in information content, there is currently a severe bottleneck in the communications of these products to end users, particularly when full-waveform recovery is desired. Bridger Photonics Inc. proposes to develop a dual-mode laser system capable of performing laser radar imaging as well as high speed free-space optical communications using the same laser source. The system will capitalize on Bridgers existing ladar technology that can provide, when needed, foliage penetration, Doppler signatures, very high dynamic range, and the highest range resolution available. Bridger will demonstrate that their system architecture is ideally positioned to seamlessly integrate high-speed free-space optical communications as an additional and potentially simultaneous mode of operation without significant alterations to Bridgers existing system components. To do so, Bridger plans to determine the subsystem design for the free-space optical communication system and model the anticipated system performance. Critical hardware demonstrations will be performed that will highlight the dual-mode operation. Finally, a preliminary Phase II design will be downselected and its costs, performance and feasibility will be determined. A Phase I option will enhance this prototype design to enable a smooth transition to a potential Phase II effort.

Title:Free-Space Optical Communications: Light Detection and Ranging Enhanced Data Delivery
Abstract:Over the past few years, lidar programs have collected 3-D imagery enabling unprecendented views of the battlefield. Unfortunately, lidar systems collect such large volumes of data that it is not available in real time. This SBIR Phase I proposal suggests a research program to design low-SWaP free-space optical communication (FSOC) system to download lidar data to a ground station at high data rates. The proposal begins with analysis of the atmospheric path and system requirements including the effects of turbulence. It continues with scaled laboratory experiments and studies of pre-processing and formatting. Finally, a concrete design for an objective FSOC system is offered.

Title:Encapsulation Technology for Increased Environmental Stability of Vertebrate Cells
Abstract:Luna Innovations is developing stabilization technology for increased long-term storage of various biological moieties (e.g. enzymes, nucleic acids, and whole cells). This unique stabilization matrix allows for extended cell viability lifetime, minimizing cell maintenancerequirements while retaining physiological activity. The proposed encapsulated cell technology will provide significant improvements in cell lifetime, operational stability, with decreased maintenance requirements, and is easily integrated into a variety of sensing based platforms allowing for optical and/or electrical reporting metrics. During Phase I Luna will demonstrate stable long-term cell viability with enhanced environmental stability for a variety of cell lines (including mammalian cells) for a minimum of 8 weeks while still retaining physiological cellular activity. Phase II will focus on extending the cell viability and function to a minimum of 6 months for an increased variety of cell types while also working to integrate the stabilization technology into a microfluidic chip for incorporation into the SafePort water analysis system.

Title:Vertebrate Cell Preservation Technique
Abstract:To address the U.S. Army need for new methods and/or materials to allow long-term storage of vertebrate cells under ambient conditions for use in portable cell-based toxicity sensors, Physical Optics Corporation (POC) proposes to develop a Vertebrate Cell Storage (VerCeS) technology based on a novel formulation for vertebrate cell lyophilization. The key component of the VerCeS modality is a novel formulation and freeze-drying process to preserve the structure and functionality of the lyophilized cells. The innovations in the VerCeS method will sustain cells for a minimum of 3 months under ambient conditions with storage temperatures up to 40 deg C. Also, VerCeS will provide a high level of readiness, which will be achieved by rapid rehydration/reconstitution of the freeze-dried cells. In Phase I, POC will demonstrate the feasibility of the VerCeS concept by developing a prototype that will meet the Armys performance metrics. In Phase II, POC plans to expand on the Phase I proof of concept work to demonstrate extended cell viability and functioning for six months with greater than 90% viability and cells ready to use in 60 min or less with minimal operational steps under the performance parameters described in Phase I.

Title:Field Portable System for Measuring Chlorinated Organic Solvents in Water
Abstract:We propose to demonstrate proof of concept and feasibility for our design for a new class of field portable sensor devices capable of rapidly detecting, measuring and classifying Chlorinated Organic Solvents (COS) in environmental waters. The proposed sensor technology is based on an innovative adaptation of surface enhanced Ramon spectroscopy that greatly increases the Raman signal strength and the sensors detection capability. A sensor with the proposed level of performance could accurately identify and quantify COS in water samples in real-time by collecting molecular conformation structures and related spectrum profile information as chemical fingerprints. The sensor system would be designed as a light-weight field portable unit capable of rapidly providing the needed quantitative measurements of COS such as trichloroethylene (TCE), dichloromethane, etc. Successful development will lead to increased COS detection speed and accuracy, greatly surpassing current approaches. The proposed project will also lead to key advances in Raman spectroscopy that can support many other valuable government and commercial products addressing a wide range of military, police, homeland security, medical and environmental sensor applications.

Title:Microfluidics-Based Organic Compounds Analysis Device
Abstract:Detecting chlorinated organic compounds in contaminated ground water is an ongoing concern due to their known toxic and carcinogenic effects. To address the Armys need for a field-portable test to detect and quantify chlorinated organic compounds in water samples, Physical Optics Corporation (POC) proposes to develop a novel Microfluidics-Based Organic Compounds Analysis (MOCA) device based on surface-enhanced Raman spectroscopy (SERS) and microfluidics. The novel device design provides compound pre- concentration, significant Raman enhancement, and microfluidics compatibility, enabling sub-ppb limit of detection (LOD), <15-min analysis time from sample collection to results, and applicability to detect other chemicals. The MOCA device requires no sample preparation and can be transitioned to a glass microfluidic chip-based design for the SafePortTM system. Additionally, the robust construction of the sensing microfluidic chip and reliable optical detection approach facilitates long shelf life. In Phase I, POC will demonstrate the MOCA device by fabricating the SERS substrate and microfluidic chip and testing compound detection. In Phase II, a fully optimized MOCA device will be developed with specifications of weight, footprint, LOD, sensitivity, selectivity, interferant effects, response time, and environmental impact. The Phase II MOCA technology will meet the Army requirements and be ready for onsite evaluation.

Title:Application of Biopolymer for Soil Revegetation and Stabilization
Abstract:Military training activities often result in environmental degradation due to creation of heavily disturbed soil areas including dirt road beds, vehicular training areas, tank trails, terrain subject to wildfires, artillery impact areas, helipads and dirt landing areas for aircraft. These areas are currently resistant to revegetation efforts and are also susceptible to sediment loss through water erosion and the generation of dust through wind erosion. Traditional revegetation and dust reduction processes requires application of a moisture retention agent, typically a petroleum-derived polymer. Surface applied fertilization provides temporary vegetative growth but often leads to nutrient transport to and utrophication of surface waters, while petrochemical products most often used as soil additives are known to leach carcinogenic monomers. Luna Innovations, in collaboration with Virginia Tech, has developed a comprehensive system for the treatment of disturbed soils with a versatile bio- based formulation for revegetation and soil stabilization. This green system will take advantage of the Armys Rhizobium tropici biopolymers unique properties and combine them with a cost effective and efficient treatment and delivery method. Lunas technology will be compatible with conventional loosening and hydroseeding equipment, and will eliminate the use of all petroleum-based additives in the formulation.

Title:Polymeric Biocomposite for Revegetation of Soil
Abstract:Defense training activities can result in reduction of vegetation cover, disturbance of soil surface and crusts, and degradation of soil aggregates, making the land more vulnerable to wind erosion. Currently, petro-polymers are being extensively studied for soil stabilization and remediation. These polymers are expensive and possibly dangerous to health and the environment. Biopolymers are promising in this regard as they not only can stabilize the soil, but also degrade into benign products, that beyond not harming the environment, may actually add to nutrients in the soil, thus hastening vegetation. MMI will develop a biopolymer biofiber composite that will not only stabilize the soil, but also act as a substrate for simultaneous revegetation. Phase I studies will focus on providing preliminary (proof-of-concept) data for methods of biopolymer/seed delivery based hydroseeding. It will be proven that the composite will prevent sediment transport in runoff water, bind soil well, preventing dust emissions, and enable rapid growth of grass cover. Based on the results of the preliminary testing and the application design schemes, Phase II will focus on pilot-scale test for application and evaluation of biopolymer for rapid re- vegetation of heavily disturbed soils in areas where soil disturbances contribute significantly topsoil loss, excessive dust emissions, and/or reduced soil fertility. This will be followed by technology transfer for large-scale field use.

Title:Physics-Based, High Resolution Soil Strength Prediction
Abstract:Effective Army-scale mobility predictions in austere environments require knowledge of soil strength conditions at high spatial resolution (100 m or less). The Armys knowledge of the battlespace is greatly hindered because available weather-scale near-surface soil moisture data, a primary indicator of soil strength, is limited by its coarse spatial resolution (1-25 km). Moreover, there are no adequate methods currently available to bridge the gap between such weather-scale soil moisture data and sparse, highly localized point data (e.g., field measurements from local weather stations). Under this effort, Creare proposes to address this critical Army need by defining, developing, and evaluating innovative downscaling and upscaling algorithms for soil moisture and soil strength prediction embedded in a modular, extensible software framework. The resulting algorithms will provide the Army with accurate estimates of near-surface soil moisture and soil strength by integrating information from disparate data sources, including low resolution weather-scale predictions; localized, sparse point measurements; and other available data that correlate with soil moisture such as elevation, slope, vegetation, and soil type.

Title:Downscaling Techniques for Ground State Information
Abstract:Reliable knowledge of soil moisture is required for numerous Army and civilian applications including mobility assessments, flood forecasting, agricultural management, erosion mitigation, and control of vector-borne diseases. Soil moisture cannot be measured at the resolution that is required for these purposes (approx. 30 m grid cells), so a simple but accurate downscaling tool is needed. The purpose of this SBIR project is to develop a commercially-viable downscaling tool with flexible data inputs. The foundation for the proposed tool is the Equilibrium Moisture from Topography modeling framework, which estimates soil moisture from high-resolution topographic data. This approach is simple and relies on universally available data. It is also broad enough to accept additional data inputs if desired by users. In the project, the methodology will be generalized to accept more diverse information, it will be implemented in software that meets the needs of targeted customers, and it will be commercialized in a sustainable manner.

Title:Improved Solar Shade (ISS) with Enhanced Durability and Performance
Abstract:Solar shading is used by the military in many different field applications as a cost effective approach to reduce fuel consumption for climate control in expeditionary shelters. These relatively simple, low cost shades offer one of the most significant energy saving solutions for expeditionary shelters in warm climates, providing greater than 70% solar block capability and an air gap (convective cooling) between the shade and the covered object which greatly lowers the effects of solar heating. However, due to the harsh service and environmental conditions, the current solar shade systems lack durability and typically only last through about one year of service. Therefore, a new solar shade material is desired that is still lightweight with the same or improved solar shading and energy saving potential, yet be more durable so the service life can extended to at least four years. METSS will address this challenge under the proposed program by modifying the textile design and improving the environmental resistance of the materials used in the solar shade construction to develop improved solar shade material that are more durable and capable of withstanding the harsh physical and environmental conditions to which these structures are exposed.

Title:Plasmonic nanowire solar shades
Abstract:Solar shading is a cost-effective solution in expeditionary shelters for reducing fuel consumption for climate control. Current solar shades are known to typically fail by fabric tearing in the degraded material after one year of use. This short service life is dramatically less than that of shelters, supplies, and equipment that the shade is expected to cover. The proposed work is to develop a next generation multifunctional shade material with enhanced durability and other advantageous attributes. The proposed shade material consists of plasmonic nanowires dispersed in a polymer that offers enhanced elastic modulus and strength, and superior solar blockage.

Title:Whole-body Anthropometric Design Models for Protective Equipment Design
Abstract:The overall objective of this work is to develop whole-body anthropometric models (containing both skin and interior anatomy) to cover individual body shape variations in the design of protective equipment as well as to identify critical fit and form issues and their associated impacts. Starting from a Template Body Model with Interior Anatomy (TBMIA), this work aims to develop automated algorithms to match this template model to 3D body scans from existing anthropometric database. The expected outcomes of this Phase I effort include a set of high-quality whole-body anthropometric design models and a prototype graphic user interface (GUI) which enables users to adjust the posture and anthropometric parameters of these models on the fly. In the Phase I, we will demonstrate the usage of these anthropometric models for penetration injury estimation with a fast shot-line penetration model capable of predicting projectile estimated kinetic energy and permanent cavity. In the Phase II, the developed software tools will be utilized to generate anthropometric models from the newest ANSUR II anthropometry database to represent the Soldier population. Model verification and validation, software optimization, and interface development and integration with other existing DoD combat simulation and/or causality prediction tools will also be conducted.

Title:Detection of Urinary Biomarkers for Assessment of Oxidative Status
Abstract:Reactive oxygen/nitrogen species (RONS) produced in the muscle by strenuous physical exertion has been correlated with degradation of muscle force output, fatigue, and muscle soreness. When the production of RONS in the body exceeds the body’s innate ability to neutralize them, oxidative stress occurs, compromising physiological function due to cellular damage. Low-level RONS production that occurs during exercise contribute to beneficial muscle adaptations by inducing up-regulation of antioxidant enzymes. Excessive consumption of dietary/supplemental antioxidants has been shown in animal and human models to negatively impact muscle adaptation to exercise and aerobic performance. Hence, it is important to maintain beneficial levels of RONS, so as not to compromise war-fighter adaptation to initial military training, and reduce combat effectiveness. A non-invasive detection system is required to assess/discern the changes of oxidative status before and after dietary intervention and physical performance in healthy and recovering war-fighters. Lynntech proposes to develop a non-invasive, portable, robust detection system for assessment of oxidative stress using innovative immunoassay platform technology. During the Phase I project Lynntech will establish the feasibility of the detection system for the identification and quantification of oxidative stress biomarkers present in urine samples.

Title:Multilayered and Arrayed Fiber Optic Sensor Suite
Abstract:To address the Army’s need for a multifunctional integrated drive system sensor to monitor rotorcraft drive system health, Physical Optics Corporation (POC) proposes to develop a new Multilayered and Arrayed Fiber Optic Sensor Suite (MAFOSS) system. It is based on integration of multiple types of fiber optic sensors arrayed on a single MEMS chip, coated with p-SiAlCN. The innovations in a new fiber optic MEMS sensor design, novel hard coating on the MEMS, and new model-based prognostic software design, will enable the MAFOSS to reliably monitor rotorcraft drive system health. Therefore, this system offers small size, light weight, fault tolerance, and capability to survive harsh aviation environments. In Phase I we will develop the MAFOSS system design and determine its feasibility through modeling, simulation, and development of a proof-of-concept prototype for bench testing; select a representative drive system component for sensor suite design and lab testing, and address usage and diagnostics models. We will also define an aircraft-level architecture and a roadmap for implementation, and address integration with existing aircraft health and usage monitoring systems (HUMSs). In Phase II, we will develop and test a fully functional MAFOSS system and multiple sensors at locations covering the entire aircraft drive system.

The predicted signal will be compared to the detected signal to detect and confirm the fault severity and location. Through this use of “smart filtering” specific faults will be identified earlier through using data under a wide range of operating conditions and the “smart filter” will ensure detection is false alarm free.

Title:Air-to-Air Targeting Algorithms for Turreted Gun Systems
Abstract:Continuing development of airborne threats has increased risk for military rotorcraft. Development of air to air targeting algorithms for a stabilized turreted gun systems has not kept pace with technology and improvements are needed to be effective against aerial systems. Military helicopters use machine guns as offensive and defensive weapons against air and ground targets. However, they have challenges in targeting airborne targets where the target is moving rapidly in three directions. Targeting errors have many sources such as tracking errors, winds, turret pointing errors. New air to air targeting algorithm approaches need to account for errors such as these to increase the accuracy. We propose the development of air-to-air targeting algorithms for a turreted gun systems such as are found on the AH-64D helicopter to achieve air-to-air accuracies equivalent to current air-to- ground accuracies with graceful degradation as error increase.

Title:Air-to-Air Targeting Algorithms for Turreted Gun Systems
Abstract:The objective of this proposal is to demonstrate the feasibility of developing novel air-to-air targeting algorithms that address many existing challenges based on state-of-the-art model- based engineering technologies. The concept being proposed is to use a software-based Targeting Algorithm Test Bed that supports plug-and-play tests of different targeting algorithms and effects, and automatically generates and/or optimizes air-to-air targeting algorithms through combining with model-based optimization and simulated annealing. The Test Bed to be developed under this project contains a first-principles model that describes the fundamental physics of air-to-air targeting under ideal circumstances; adaptive data processing algorithms that result in better information acquisition; data filters that remove unwanted random errors; an accurate target-tracking algorithm that tracks and predicts the target location; a CFD model that simulates the aerodynamics effects to bullets; a surrogate model that mimics the CFD model to reduce computational time; a control system that manages, commands, and directs the behaviors of all devices in the targeting system. The software will combine ideas from object-oriented programming and hybrid simulation, and has an “open” architecture, which makes it easy to integrate with other software. It will be ideal for developing highly modular air-to-air targeting simulation software that meets the JMR requirements.

Title:3 kW Lightweight Efficient Generator
Abstract:Soldiers are very dependent on electrical power for laptops, radios, handheld devices, smart phones, ISR platforms and weapon systems. Existing generators are heavier and lack compatibility with readily available fuels. They must operate reliably across a wide range of environmental conditions. A lightweight, robust generator with multi-fuel compatibility would increase flexibility for the soldier and the unit, and it would reduce the logistical footprint. A more compact, efficient unit would enhance portability by soldiers and reduce fuel costs across the inventory. The focus of this SBIR is to design, develop and demonstrate a compact, lightweight and efficient multi-fueled, 3 kW power unit. The proposed generator system will be based on a very compact and efficient recuperated turbogenerator design with advanced controls and electronics. The turbogenerator will output a continuous 3 kW power at 1,000 feet and 107 degrees F. In addition, it will weigh significantly less than fielded units, run on a variety of fuels (JP8, diesel, and gasoline), generate reduced noise signature, have reduced maintenance, and offer extended life. The resulting system will provide a reliable power source to soldiers while enhancing portability and reduce fuel costs across the inventory.

In the Novatio prototype, diesel or JP-8 fuel is aerosolized into very fine droplets (<1 micron), thus enabling pre-mixing of fuel and air that is required for operation in spark ignited mode. The enabling technology is patented low cost, compact and efficient means to produce an on-demand aerosolized stream of fuel ready for mixing with air for Otto cycle operation and that can readily be scaled up to the 3 kW size range.

Title:Nonlethal Warhead for Miniature Organic Precision Munitions
Abstract:Our proposal describes a multi-functional, non-lethal (NL) warhead for miniature organic precision munitions, which combines: kinetic, blast, flash, dazzle and chemical effects in a single warhead designed to provide incapacitating effects out to 4.25m. The first innovation involves high-density, micro-spheres to deliver less-than-lethal but incapacitating effects to personnel at an extended range. Small, NL warheads with large (~10mm), rubber balls have a low probability of hit and low velocity due to drag at extended range, thus a low probability of incapacitation. Small NL warhead with small (~ 1mm), high-density, micro-spheres, e.g. steel balls have a high areal density and velocity, thus a hit probability of hit and incapacitation. The second innovation is EMPIs novel reactive multi-phase blast compositions, which allows for extended blast and flash effects. In order to maximize the effectiveness, the case will be composed of reactive metal particles in an epoxy, which converts to ultra-fine reacting particles for additional flash without producing any lethal fragments. Finally, our concept is based on a HOB fuze to focus the NL effects in a conical, downward pattern while sending the platform fragments outward and rearward. EMPIs NL warhead will be compatible with ATKs SOPM warhead. ATK personnel provide technical oversight.

Title:Malodorous Non-Lethal Grenade
Abstract:To address the Army need for a non-lethal warhead for use on miniature organic precision munitions, Physical Optics Corporation (POC) proposes to develop a new Malodorous Non- Lethal Grenade (MNLG) optimized for use on miniature munitions. This proposed grenade is based on a new design that utilizes both government developed and POC developed and tested components. The innovation in the grenade design and its delivery to the target will enable the accuracy and effective incapacitation of enemy personnel while assuring non- lethality and low probability of collateral damages. The grenade design satisfies stringent requirements on the size and weight of the non-lethal warhead as well as on manufacturing the warhead at low cost, thus directly addressing the Army requirements. In Phase I, POC will demonstrate the feasibility of the proposed grenade design and its capability of interfacing with munitions systems. In Phase II, POC will demonstrate and test the breadboard warhead prototype and prepare it for the flight test in Phase III.

Title:Autonomously Adaptable Wireless Power Charging System
Abstract:A need exists within the Nett Warrior program to wirelessly charge soldier mounted electronic devices. Currently soldiers either carry extra batteries or dismount their electronics and deal with the logistics of a variety of cords to charge their electronic devices. Current wireless inductive chargers suffer from range limitations, and require complex control electronics to properly couple the transmitter and receiver devices. Busek has developed an autonomously adaptable wireless power charging circuit. Its design allows the fundamental oscillating frequency to be almost completely determined by the load. This means what was previously accomplished in active control software is realized by the nature of the circuit itself. The advantage of load determined resonance is the inherent ability for the circuit to deliver maximum power without actively tuning the operating frequency for maximum coupling. In Phase I the self-tuning wireless charging circuit will be developed. This circuit will be analyzed and adapted for use as a transmitter. Its performance will be evaluated and analyzed when coupled to single and multiple loads. The safety and performance of the circuitry via 3-D electromagnetic simulations will be evaluated. The goal is to ensure electric and magnetic field strengths remain within safe exposure limits while providing suitable efficiency.

Title:Cordless Battery Charging
Abstract:Today’s warfighter and NETT Warrior are reliant on small battery operated devices for communication, information systems, enemy detection, and battlefield management. These devices must be recharged on a regular basis to ensure sustained operation. Current charging technologies require the device to be plugged into a charging station via a wired connection. This wired power connection requirement decreases the battlefield flexibility due to limited number of units that can be charged at one time. The Nett Warrior uses a battery to power various Soldier-worn components. Space limitations and the dynamic nature of the battlefield suggests that carrying extra batteries and chargers will adversely impact the Soldier's mobility and readiness while transported by a ground vehicle. Cordless battery charging technology could have a dramatic impact on the portable electronic devices being used on the modern battlefield. This cordless technology could be harnessed in several applications to ease the logistical footprint and increase the flexibility of the devices. The goal should allow the operations served by the wireless battery charging system to stay and go wherever needed. We aim to achieve and implement a design that will support smart and intelligent and highly efficient cordless/wireless battery charging at a range of 2 feet.

Title:Arete Active Downrange Crosswind Sensor for Small Arms Fire Control
Abstract:Arete Associates proposes to develop a stand-alone active crosswind sensor operating at the eye safe wavelength of 1.5 microns. The sensor is based on a novel design using a single beam, and a single-channel under-resolved receiver. The error on the crosswind measurement will be less than 1.5 m/s for winds from 0 to 20 m/s, up to a range of 1.5 km. The sensor system will meet the objective SWaP requirements listed in the solicitation, which will make it suitable for day/night one-man operation.

Title:Downrange Crosswind Sensor for Small Arms Fire Control
Abstract:Based upon nVision Technology employee's experience developing the DARPA One Shot system and the VALR wind measurement system through another DoD customer, nVision Technology proposes using scintillation-based wind measurement techniques for both passive wind measurement as well as pseudo-profiling along the entire range from the shooter to the target. By modifying existing hardware nVision can quickly adapt the system to perform passive measurements as well as provide a level of wind profiling that will increase the probability of hit on target.
