Title:Low-Cost, High Performance Transparent Armor
Abstract:A new single crystal alumina nanocomposite material is in development that has the potential to be an excellent hardface material for transparent armor. This project will develop a version of the new material specifically for transparent armor applications. The material is expected to have mechanical properties and ballistic performance roughly equivalent to, or better than, aluminum oxynitride (ALON). ALON is ballistically superior to transparent spinel and single crystal sapphire. Extrapolation of data within the public domain indicates that transparent armor performing at this level will defeat benchmark small arms threats at an areal density of approximately 7 lb/ft2 (34 kg/m2). The process to make the single crystal alumina nanocomposite material is expected to drastically reduce cost relative to the other transparent ceramic materials when scaled up for production. In the Phase I project, small transparent hardface specimens will be made and tested for optical and mechanical properties. The material's anticipated ballistic performance will be predicted from the mechanical properties. A plan for (Phase II) ballistic, optical, mechanical, and physical testing of larger armor specimens will be derived, and a producibility study will be done to determine estimated unit costs for hypothetical production of small to large transparent armor parts. (P-00857) Successful development of the new single crystal alumina nanocomposite material will allow the use of transparent armor having very high ballistic performance at much lower cost than existing transparent ceramics. Military applications include windows and vision blocks for armored vehicles, ballistic shield windows, face shields and goggles, aircraft transparencies and sensor windows, infrared domes for missiles, and laser ignition windows for medium and large caliber cannons. Commercial applications include law enforcement vehicle windows, ballistic shields, face shields, and executive protection armor configurations.

Title:An Ultralightweight Nanocomposite Opaque Ballistic Shield
Abstract:New technology is required to demonstrate a multi-hit material that can defeat multi-threats at less than 4 lbs/ft2. Nanotechnology based engineered materials have the potential to demonstrate substantial ballistic performance enhancement over state-of-the-art armor systems. Recent developments in nanocrystalline ceramics have demonstrated ballistic performance that meets current weight goals but lacks the multi-hit capability. Nano-reinforced polymers have demonstrated exemplary ballistic performance with multi-hit capability. Combining nanocrystalline ceramic and nano-reinforced polymers in a multilayer composite that somewhat mimics seashell architectures has the potential to provide multi-hit capability against multi-threats at less than 4lbs/ft2. This program will fabricate, ballistic test, identify the relationship of the layers on ballistic performance, initiate compositional/layer optimization and deliver ballistic shield samples to SOCOM for further ballistic test confirmation The development and demonstration of a paradigm in advanced ultra-lightweight armor materials will have immediate applications in all military deployment, in law enforcement, security police, private vehicles, boats and buildings, and a variety of structural and aerospace applications.

Title:Advanced Ballistic Shields Made Ultra-light and Affordable
Abstract:New materials are needed to reduce weight of ballistic shields, but they MUST be affordable in order to support commercialization goals. Reinforcing ceramics with fibers can reduce the weight of the opaque components and at the same time increase multi-hit capability and damage tolerance. MSE-AML proposes a cost effective approach to fiber reinforced ceramic composites for ballistic applications that is attractive for commercialization. Regarding the transparent materials, the primary challenge is to satisfy both the multi-spectral requirement and achieve the hardness necessary for good ballistic performance. A hot pressed mixture of multi-spectral materials of various hardness and cost has potential to provide an affordable solution. Both transparent and opaque materials must be combined efficiently in shield manufacturing and assembly processes to achieve optimal benefit. Phase I will demonstrate ballistic efficiency of the fiber reinforced ceramics and will investigate feasibility of performance and economics of the transparent material. Our ultimate goal is to develop and deliver SOCOM a shield with a reasonable area of protection against small arms fire in both opaque and transparent parts that is curved and comfortable to carry weighing significantly less than 20 pounds. The proposed fiber reinforced ceramics have the potential for wide spread use in the armor market due to their attractive properties including multi-hit capability, damage tolerance, shape flexibility, and manufacturability. They also have utility in wear applications and high temperature applications. Transparent materials for ballistic protection are important to all branches of the military. Potential non-armor applications include domes and windows.

Title:Sympathetic Detonation Underwater With Optical Means
Abstract:The requirement for a light weight underwater detonator arises from the need to provide a reliable trigger signal under all conditions. The object of the Phase I is to determine the feasibility of an optical self-generating signal that has low power/energy requirments. This device will have a simple user interface and rugged construction. The aim of the proposed program is to build a prototype unit and evaluate it under a variety of realistic conditions. The results of this work are expected to be an underwater detonator that sends a reliable, unique signal due to a self-generating optical method. The commerical application of this device mining, demolition and avalanche control.

Title:Innovative underwater trigger signaling system
Abstract:For sympathetic underwater detonation, wireless triggering is highly desirable. A wireless trigger would avoid the problems associated with installing long, wired connections, and would permit a much larger stand-off from the detonation. Wireless underwater signaling, however, continues to be a difficult problem. For example, radio and acoustic waves have severe problems under water and near shore. A new type of signaling technology is proposed here. The technology takes advantage of properties of water which have not previously been used for communications purposes. A plan is presented to develop an underwater trigger signaling capability with this technology, and provide evidence that a trigger signaling system can be implemented with useful range and triggering capability. Successful preliminary feasibility test results are presented. The proposed technology will provide a new and effective method for underwater trigger signaling. It will allow trigger signals to be transmitted over significant distances. It is anticipated that the proposed solution will be very cost effective and provide signaling capability in a wide range of underwater conditions. The proposed technology has commercial application for SCUBA communication systems and communications with underwater craft.

Title:Trimmable Waterjet Nozzle for Small Craft
Abstract:Under some conditions, many boats are susceptible to burying their bow into oncoming waves. In the case of SOCOM's new NSWRIB, the low bow profile, relatively high loading and soft inflatable sponson exacerbate this concern. In this project we investigate several methods to reduce bow stuffing. These include pushing down at the back of the boat with trimmable jet nozzles, bendable transom trim tabs and aft movement of the Cg. We also look at holding the front up with an additional lifting surface, or `hydroski', which is bolted to the bow and is normally above the waterline, but provides large vertical force when needed. Advanced dynamic computer modeling, and instrumented ocean testing of 1/8 and _ scale prototypes in Phase 1 will demonstrate the feasibility of an eventual low cost retrofit for production boats. This project has an immediate application to production SOCOM small craft as well as commercial and recreational craft, and should lead to a better understanding of planing boat behavior in waves.
