Abstract
Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport.  Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight.  Scramjets contain no rotating shafts from which typical generators or mechanical pumps can be run.  The energy source that is available during hypersonic flight is heat.  We  propose the use of the tremendous abundance of waste heat that occurs during hypersonic flight to produce electric power using a solid state heat engine.  The Engine, using the compression and expansion of gas through electrochemical cells (similar to fuel cells) yields a Carnot equivalent cycle to convert any heat source into viable electric power.  Leveraging our our subcontractor''s existing experience in hypersonic flight technologies, we shall analyze available heat sources and develop a comprehensive design for the heat engine to produce the required 100kW of electrical power.  Phase I will produce a working design for both the desired 100kW system and a 1 kW prototype to be built during a subsequent Phase II effort. BENEFIT: Implementation of the proposed heat engine technology will provide a vehicle to produce additional electricity during flight to operate electronic systems and related equipment.)
