aerospike engine

[‚e·rō¦spīk ′en·jən]
(aerospace engineering)
An advanced liquid-propellant rocket engine that uses an axisymmetric plug nozzle, in combination with a torus-shaped combustion chamber and a turbine exhaust system that injects the turbine drive gases into the nozzle base, to achieve a geometry that is only one-quarter the length of a conventional rocket engine, as well as automatic altitude compensation, resulting in superior low-altitude performance.

The first hot-fire tests of the FRE-2 aerospike engine are expected to take place in early 2016.
Similar performance improvements would also result from utilizing the first-stage aerospike engine to attain LEO orbits.
Most recently, Rocketdyne developed the Linear Aerospike engine, which demonstrates key technologies and lower operating costs needed for the next generation of reusable launch vehicles.
To support the SLI initiative, Rocketdyne drew on the expertise of engineers fresh from two engine development efforts, the RS-68 for the Boeing Delta IV expendable launch system, and the Aerospike engine for NASA's X-33 advanced technology demonstrator.
New aerospike engine will do for space travel what the jet engine did for air travel
The aerospike engine concept dates back to at least the 1960s, but while it has been the subject of analysis and ground tests there had never been an actual flight test - until the March 30 and 31 flights of two 10-foot-long solid-fueled rockets with aerospike nozzles.
for the final phase of testing to qualify the innovative Linear Aerospike engine that will power the experimental X-33 rocket plane being developed by a Lockheed Martin-led industry team and NASA.
Fourteen single-engine test firings of a development configuration of the unique aerospike engine were successfully completed at Stennis Space Center last year, followed by a series of dual-engine tests that was concluded late this spring.
To meet the challenge of next-generation propulsion, Rocketdyne will build on the experience gained from the development of the SSME, as well as the RS-68 engine for the Boeing Delta IV expendable launch vehicle and the Linear Aerospike engine developed for NASA's X-33 reusable launch vehicle.
The aerospike engine lacks the conventional bell-shaped exhaust nozzles of other rocket engines.

The aerospike engine design is distinguished by ``ramps'' that shape its thrust and the lack of conventional bell nozzles like those on the space shuttle.
