  1. Affordable High Power Density Engine Designs for Personal Air Vehicles

    SBC: GSE, Inc.            Topic: T701

    Next generation General Aviation (GA) Sport Class air vehicles limited to 1200lbs, represent the first opportunity to overhaul the FAA certification process necessary to manufacture affordable aircraft. With propulsion representing over one-third of the direct manufacturing costs of the entire aircraft, dramatic reductions in aircraft engine costs must be achieved by design, economy of scale, and ...

  2. An Integrated Heavy Fuel Piston Engine Ducted Fan Propulsion Unit for Personal Air Vehicles

    SBC: GSE, Inc.            Topic: T701

    The proposed PAVE propulsion system technology demonstration combines an innovative high-speed aero-diesel engine with a novel ducted fan assembly resulting in a low noise/cost and high performance propulsion system. The core engine makes extensive use of a novel self-injection, compression ignition/combustion system capable of high-speed operation on kerosene-based fuels without degradation due ...

  3. Ultraviolet AlGaN-based Avalanche Photo Diode Grown over Single Crystal Bulk AlN Substrates

    SBC: Sensor Electronic Technology, Inc.            Topic: E101

    Premature breakdown is a key obstacle in developing AlGaN-based avalanche photo diodes (APD) for ultraviolet (UV) light detection. Novel materials growth techniques, such as Hydride Vapor Phase Epitaxy (HVPE) allows for reduction of dislocation density only to approximately 10^7 cm-2. In order to reduce the number of growth defects and dislocation density in AlGaN-based APDs we will use single cry ...

  4. Miniature Adsorption Blast-Freezer for Use in Space

    SBC: Rocky Research            Topic: N/A

    Adsorption refrigeration using ammoniated complex compounds as the absorbent media can be used for miniature portable blast freezers. This is possible because the technology allows low evaporator temperatures without staging, is scalable to small sizes, and has high reliability because the only moving parts are check valves. Compared to vapor compression or other sorption refrigeration systems, th ...

  5. Uniflow Two-Cycle Aero-Diesel Powerplant

    SBC: G.s. Engineering Inc.            Topic: N/A

    This proposal outlines the design and development of a uniflow two stroke Aero-Diesel engine core in response to the NASA SBIR solicitation for a general aviation aircraft propulsion system. The proposed engine will offer increased power density, simplified operation, reduced emissions, noise, and vibration, while enhancing reliability and safety when compared to currently available general aviati ...
