The current project will develop and demonstrate a prototype compact, power-efficient all-fiber lidar unit for wind profiling on board UAV's and other aircraft. The system leverages Oceanit's current fiber-laser based lidar development efforts. A unique design provides a rugged system with no moving parts and little maintenance requirements. Efforts in the current project will include prototype s ...

This NASA SBIR Phase II project will produce a flight suitable test bench based on a modular spray-cooled assembly that considers NASA power and mass budgets and can be scaled to cool multiple heat sources producing high heat fluxes under gravity and microgravity conditions. Thermal management solutions for certain NASA applications like laser diodes are not all that suitable with a need for a be ...

In Phase I of this project, APEI, Inc. proved the feasibility of creating ultra-lightweight power converters (utilizing now emerging silicon carbide [SiC] power switching technologies) through the successful demonstration of power switch operation up to 500 oC. The goal of Phase II will be to design, fabricate, and fully test SiC based DC/DC converters that can achieve high power density and ultr ...

The goal of the project is research and development of methods for application of the Hybrid FE-SEA method to aircraft vibro-acoustic problems. This proposal discusses the development and application of new methods of structural-acoustic analysis in order to address existing problems in aircraft interior noise prediction. The proposed methods are based on a hybrid modeling strategy that combines ...

In Phase I, APEI, Inc. proved the feasibility of developing a modular, expandable and fault tolerant SiC-based power system through the successful demonstration of a four-module SiC-based power system capable of dynamic reconfiguration allowing the system to continue delivering power to the load without interruption in the event of a module failure. These results show the feasibility of developin ...

This proposed project will attempt to develop a data analysis system for structural health monitoring on space structures. The data analysis software will be a key component in space vehicle health management system and can be used to in vehicle life prediction. The sensor data analysis algorithm is aimed at providing a modeling and simulation tool for data collected from a network of distributed ...

Sierra Engineering Inc. (Sierra) believes that the subject triaxial liquid propellant swirl injector has the potential to meet many of NASA's Earth-to-Orbit (ETO) propulsion systems goals. The triaxial swirl injector is ideally suited to a wide range of liquid oxidizers and fuels, including hydrogen and a wide range of hydrocarbons. It holds the potential of excellent high-frequency combustion st ...

Sierra Engineering and Purdue University propose to leverage combustion stability testing, already funded and planned for the second and third quarters of next year at Purdue, by developing a non-intrusive plume instrument capable of detecting combustion instability and testing it during combustor firings. Purdue has previously created the combustor and demonstrated unstable combustion operation. ...

This Small Business Innovation Research Phase I project seeks to prove the feasibility of creating high-temperature silicon-carbide (SiC) based motor drives for extreme environment exploratory robotic missions (such as Venus landers). SiC digital control ICs will be developed for controlling power electronics systems (such as motor drives) and integrated with SiC power switches into a multichip po ...

This Small Business Innovation Research Phase I project seeks to investigate and prove the feasibility of developing ultra-wide temperature (-230 oC to +130 oC) motor drives utilizing Silicon-Germanium (SiGe) asynchronous logic digital control electronics. Asynchronous circuits remove the concept of a global clock by incorporating handshaking protocols to control the circuit. The handshaking pro ...
