  Objective:  Develop a system integration environment for design, analysis, and optimization of airborne directed energy systems.
  Description:  The design of airborne directed energy systems presents a challenge due to the use of high-power, tightly-regulated, low-efficiency loads and the size, weight, and thermal constraints of the aircraft. Although steady-state analysis and component optimization is vital in the initial design phase, these techniques may yield too conservative of a solution that is not feasible for integration within the aircraft. Therefore, an overall system optimum is required wherein the transients and steady-state performance are optimized for such tightly-coupled systems. The intent of this effort is to establish an environment wherein detailed transient models of the various subsystems can be integrated to form an end-to-end system simulation. The environment must include DE devices such as solid state lasers and wide-band systems. System-level constraints include, but are not limited to, prime power, power conditioning, thermal management, and coupling apertures and antennas. System-level optimization techniques can then be applied with respect to power quality, size, weight, and thermal constraints. Trade studies can then be performed with respect to on-time, effectiveness, and range. The overall goal of the study consists of developing and demonstrating the necessary computational techniques to perfect a virtual prototype of a DE system on a representative airframe.

  PHASE I: Define technical approach for an integrated directed energy system simulation and for system-level optimization. Demonstrate feasibility of this approach for a representative directed energy system.
  PHASE II: Design and develop system integration environment. Implement system-level optimization algorithms. Demonstrate capability for an airborne directed energy system.

  DUAL USE COMMERCIALIZATION: Military application: Complete packaging of system integration and optimization software and implement using an airborne directed energy system. Commercial application: Complete packaging and system intergration for radio frequency sources.
