Propulsion Powertrain Simulator: Future turboelectric distributed-propulsion aircraft
IEEE Electrification Magazine, 2014The NASA Glenn Research Center, in collaboration with the aerospace industry and academia, has begun the development of technology for a future hybrid wing-body electric airplane with a turboelectric distributed-propulsion (TeDP) system. It is essential to design a subscale system to emulate the TeDP power grid, which would enable rapid analysis and ...

Trends in Military Aircraft Propulsion
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1989The major factors determining the choice of engine cycle for a combat aircraft are the requirements of the design mission and those of aircraft speed and agility. The requirement for jet-borne flight in short take-off vertical landing (STOVL) aircraft imposes further demands on cycle and configuration.

Hypersonic flight [scramjet aircraft propulsion]
IEEE Spectrum, 2004Current turbojet engines cannot propel an aircraft to hypersonic speeds -their spinning shafts and compressors would simply collapse. To solve this problem, groups in the United States, Japan, Australia, and other countries are working on a propulsion system that burns fuel combined with air flowing at supersonic speeds through the engine, which is ...

The future of aircraft propulsion
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000The next century offers many challenges to the aero-engine industry in both the civil and the military markets. The primary driver in both markets will be to reduce the cost of acquiring, operating and supporting the product throughout its life. Reducing the environmental impact will be an additional challenge for the civil sector.
