SBC: METROLASER, INCORPORATED Topic: AF16AT06
A diagnostic is proposed for obtaining instantaneous three-dimensional volumetric distributions of density in a flow field at velocities ranging from subsonic to supersonic. Two variants of laser-based Rayleigh scattering will be investigated, each of wh...STTR Phase I 2016 Department of DefenseAir Force
SBC: ADA TECHNOLOGIES, INC. Topic: AF09BT22
The ever-decreasing size of the electronic microchips and the ever-increasing density of electronic components required to support future Air Force platforms are creating the problem of substantial localized heat generation that can impair component operation. State of the art thermal interface materials (TIMs), that are used to dissipate heat from the source to the spreader in a microchip, are se ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Kassoy Innovative Science Solutions Topic: AF09BT38
Quantitative predictions of reactive flow dynamics from large-scale simulations of Liquid Rocket Engines (LRE) appear to be model dependent. Relationships and coupling among the dominant mechanisms most responsible for destabilization are obscured by the complexities of the model and subtle consequences of inherent ad hoc approximations not supported by mathematical rationale. The reliability of ...STTR Phase I 2010 Department of DefenseAir Force
Theoretical Innovations in Combining Analytical, Experimental, and Computational Combustion Stability AnalysisSBC: Metacomp Technologies, Inc. Topic: AF09BT38
The occurrence of combustion instability has long been a matter of serious concern in the development of liquid-propellant rocket engines due to the high rate of energy release in a confined volume in which energy losses are relatively small. Shear layer instabilities and intermittent growth rates of the mixing layer cause fluctuations in the burning rates and result in acoustic waves triggering ...STTR Phase I 2010 Department of DefenseAir Force
Theoretical Innovations in Combining Analytical, Experimental, and Computational Combustion Stability AnalysisSBC: HYPERCOMP INC Topic: AF09BT38
Combustion stability is an important consideration in the design of liquid rocket engines. While fundamental modes of unstable operation in simple geometries are easily identified using analytical methods, recent times have seen these methods greatly expand in scope, applied in semi-numerical format to increasingly complex geometries and flow situations. Much remains to be explored in understandin ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Aegis Technologies Group, LLC, The Topic: AF09BT33
Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Electronics of the future, Inc.. Topic: AF19BT001
The focus of this proposal is FA-002 - artificial intelligence (AI), which will be used for the hardware cyber security. AI will link the THz and sub-THz responses at the pins to the defects and deviations from design of the integrated circuits under test. An increasing complexity of digital and mixed-signal systems makes establishing the authenticity of a chip to be a key problem. New rapid, inex ...STTR Phase I 2019 Department of DefenseAir Force
SBC: TAU TECHNOLOGIES LLC Topic: AF19AT007
Efficient design, build, and test of an HEL system leverages modeling and simulation (M&S) to reduce cost and increase robustness. Designers use models to explore parameter variations and to estimate performance in conditions which cannot be tested due to physical or financial constraints. This provides significant savings in cost and time. Because live testing is so expensive, it is best used as ...STTR Phase I 2019 Department of DefenseAir Force
SBC: STELLAR SCIENCE LTD CO Topic: AF19AT007
We will deliver a new software architecture for scene generation named the Realistic Image and Neighborhood Generator (RING). Instead of being tied to a single tool, RING will provide interfaces suitable for a wide variety of image and scene rendering tools to run and interact with other codes. As an initial implementation of the interfaces, we will incorporate Stellar Scienceâ€™s powerful, f ...STTR Phase I 2019 Department of DefenseAir Force
SBC: ITN ENERGY SYSTEMS, INC. Topic: AF09BT33
This Small Business Technology Transfer Research phase I program will develop a new class of uncooled THz detectors for the 1-10THz band with a novel design using surface plasmon resonant cavities with integrated metal-insulator-metal tunneling diodes as the detecting element. Tunneling diodes provide ultrafast broadband response, potentially into the visible (300THz), but demonstrated performanc ...STTR Phase I 2010 Department of DefenseAir Force
