Rotating Detonation Engine
A rotating detonation engine (RDE) uses a form of pressure gain combustion, where one or more detonations continuously travel around an Annulus (mathematics), annular channel. Computational simulations and experimental results have shown that the RDE has potential in transport and other applications. In detonative combustion, the flame front expands at supersonic speed. It is theoretically up to 25% more efficient than conventional Deflagration, deflagrative combustion, potentially enabling increased fuel efficiency. Disadvantages include instability and noise. Concept The basic concept of an RDE is a detonation wave that travels around a circular channel (annulus). Fuel and oxidizer are injected into the channel, normally through small holes or slits. A detonation is initiated in the fuel/oxidizer mixture by some form of igniter. After the engine is started, the detonation is self-sustaining. One detonation ignites the fuel/oxidizer mixture, which releases the energy necessa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA RDE
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States's civil list of government space agencies, space program, aeronautics research and outer space, space research. National Aeronautics and Space Act, Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the American space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo program missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program and oversees the development of the Orion (spacecraft), Orion spacecraft and the Sp ...
