English

Subject field(s)
  • Aircraft Propulsion Systems
OBS

A ramjet engine is a mechanically simple aerospace engine that creates thrust by burning fuel similarly to a normal jet-aircraft engine. The big difference between a jet engine and a ramjet is that a jet-turbine uses fans to compress air to optimize combustion, and a ramjet creates air-compression by the forward motion of air through a partially-restricted intake system. Ramjets have no moving parts, which is a big advantage in comparison to the delicate turbine blades in a normal jet-engine, however ramjet engines typically are not very efficient below speeds of Mach 2.

English

Subject field(s)
  • Aircraft Propulsion Systems
DEF

A ramjet in which the combustion takes place within a supersonic airflow.

CONT

A ScramJet is a "Supersonic Combustion Ramjet" this device is built to function very similarly to a ramjet with the exception that it may burn hydrogen as a fuel instead of conventional jet-fuel. Because of the different fuel and an optmized design, a ScramJet engine is capable of hypersonic speeds of Mach 6 and above.
