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.

Its product development strategy is based on two key elements: I.-reusability, We will use existing and proven technologies in others industries that we transfer to aerospace sector, Ii.-cost efficiency, For it will use aerospike engine thats feasible thanks to metal 3d print technology- return to base capabilities and reusable methane and liquid oxygen propellants, Which are 5-10% more efficient and may be the standard of the market in 20 years.
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.
However, the team will take advantage of any such advancements in scientific material to further improve the aerospike engine's performance in the future.
VentureStar will also be cheaper because the aerospike engines are built into the spacecraft.
