Leveraging the results of our Phase I work, the Torch Team proposes to execute laboratory-based experiments to elucidate fundamental micro-debris formation mechanisms to improve optical modeling of impacts. Optical signatures from impacts collected over the last decade have identified definitive micro-debris parameter trends. However, current theories have difficulty reproducing these optical ob ...

This Phase II effort demonstrates the feasibility of integrating a chemically powered or “active” infrared (IR) treatment into an inflatable device and then perform three experimental excursions with the hardware: 1) achieve a tunable IR signature by cooling the surface; 2) achieve tunable IR emissions combined with a predetermined and fixed radar cross section (RCS); and 3) achieve both varia ...

Pikewerks'Protection for Industrial and Environmental Controls from Exploitation, or PIECE, will be a cross-platform suite of capabilities providing anti-exploitation and anti-reconnaissance for Industrial Control Systems. PIECE will provide a suite of capabilities for Windows, Linux, VxWorks, and legacy devices that ensure survivability of critical infrastructure equipment. Anti-exploitation ...

The technology, theory and fabrication of metamaterials have seen impressive progress in the last few years, and various applied fields have benefited from the flexibility of electromagnetic response that metamaterials provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have been proposed for breakthrough novel applications in m ...

The mission of this proposed research is to develop a high-voltage, high-capacity, and inexpensive cathode material for lithium-ion batteries (LIB) capable of supporting high transient and pulsed loads while offering enhanced safety and lifecycle performance. Currently LIB is one of the most promising battery technologies that can provide higher energy density than other batteries. It also does no ...

There is an unmet demand for nano-scaled ultra-low-power low-cost radios to address field-deployable and massively producible sensing and communication networks in future military and commercial applications. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by exploiting the holistic integration of THz radio transceiver system, on-chip antenna ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

The AEgis Technologies Group proposes to develop an innovative real-time thermal solver solution to model hardbody thermal histories. This thermal solver solution will consider the relevant phenomenology associated with MDA targets and other associated objects requiring thermal histories. Modeling of complex objects and advanced features such as model ablation and dynamic surface areas will be co ...

ABSTRACT: This project will develop and demonstrate a software package based on coupled Fokker-Planck (FP) - Fermi Kinetic Transport (FKT) models and full-wave Maxwell electromagnetic (EM) solver to accurately predict semiconductor device behavior from dc up through the mm-wave and THz frequency ranges. The FP model provides accurate non-equilibrium occupation functions for hot electrons with real ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...
