Spectral Sciences, Inc. (SSI), proposes to develop the Enhanced Particle Simulation Toolkit (EPSilon Toolkit) software. The Epsilon Toolkit is a set of consistent, validated, physics-based particle models in a single software-library that can be easily accessed from existing MDA plume signature codes. The primary application will be to improve the modeling capabilities of BMDS propulsion and plume ...

We propose to develop a new and innovative capability to model complex target plumes by upgrading the SOCRATES-P direct simulation Monte Carlo (DSMC) high altitude plume signature code. This capability will enable SOCRATES-P to simulate 3D plume flowfields in a unified manner, from inside the nozzle to the far field, and include plume-plume, plume-body, angle-of-attack, and other complex target ef ...

Physical Sciences Inc. proposes to measure and model the Al-Al_2O_3 particle behavior in the exhaust flow of solid rocket motors (SRM) to ensure the development of a robust and accurate physics based exhaust plume flow field and signature prediction capability. An existing highly instrumented SRM flow field simulation facility will be used to conduct experimental measurements enabling the calibra ...

Missile defense takes place in a dynamic, uncertain environment. Multi-raid attacks threaten to overload sensor capabilities, leaving fewer sensor resources free to observe each target. Moreover, the shift in emphasis toward early intercept, coupled with the growing importance of short- and medium-range threats, reduces the time available for detection, tracking, and discrimination, because engage ...

Triton Systems proposes to develop advanced methodologies, for protection of Critical Program Information (CPI) of BMDS assets against exploitation by reverse engineering and tampering through the use of Side Channel Attacks (SCAs) on Field Programmable Gate Array (FPGA) devices. Specifically, a method to confuse and defeat SCAs that utilize timing information and electromagnetic leaks will be de ...

The diode pumped alkali laser (DPAL) allows for a potentially scalable approach towards a MW-class high energy laser system. By using an alkali vapor gain medium, one overcomes the intrinsic thermo-optical limitations of more conventional diode-pumped solid state laser (DPSSL) media. High spectral brightness diode pump sources are proposed by TeraDiode as the enabling element for efficient, kW-c ...

An enhancement opportunity exists in the current systems where weight reduction may be achieved by utilizing rocket thermal energy to provide recharge power to onboard batteries. In this proposal, Giner, Inc. and Purdue University describe an approach for a thermal power generation system that exploits the rocket waste heat to provide reactant gases from solid storage to an efficient, power-dense ...

Realization of high-performance compact lasers will require the development of substrates and advancements in optical coatings that can withstand the harsh environments of corrosive gases, high temperatures, and high energy densities. Toward this end we intend to undertake the development of novel optical coatings that will simultaneously provide the necessary protection and maintain the optical ...

Exact formulations of weapon-to-threat assignment problems have long been identified as binary polynomial optimization problems which are theoretically difficult (NP-hard), thus previous research for implementation in the area has focused on heuristic solution methods or methods which compromise full formulation with limits on assignment. The introduction of sensor pairing further complicates for ...

Triton Systems proposes to develop near-zero power advanced sensors, for protection of Critical Program Information (CPI) of MDA/BDMS assets against exploitation by reverse engineering and tampering through the use of X Ray imaging. The proposed technology will be applicable to both current and future hardware. During Phase I, Triton Systems will develop the conceptual framework for the new ...
