Interaction of shock wave should be consider to further design of the subsonic diffuser of the ramjet engine
The SSST engine, designated MARC-R-282, is based on the Variable Flow Ducted Rocket (VFDR) ramjet engine
The Yakhont is touted as possessing an over-the-horizon range, a dual-mode radar seeker, a ramjet engine
for supersonic speed (up to Mach 2.
Space Access is trying to develop a multistage space launch system centered on a ramjet engine
using a proprietary ``ejector'' technique and powering an ``aerospaceplane'' that the company expects will prove to be vastly superior to today's rockets.
In a nutshell, our new facility is for testing solid fuel ramjet engines
and there are a couple of things that distinguish it from most of the others that are available," said Orbital ATK's missile products divisional vice-president and general manager, Pat Nolan.
, currently used in missiles, will then take the plane up to altitudes of 32km as the plane cruises at speeds beyond Mach 4, or four times the speed of sound.
The Vesta (see title picture) programme is aimed at studying new ramjet engines
to power the Asmpa--a further development that will be introduced on the Rafale in 2008.
Conceived in 1946 and scarcely more than a frame with a rotor and tail, the XH-20 was powered by two ramjet engines
that, like the aircraft, were developed by James S.
Such heating would destroy turbine or ramjet engines
constructed of any known material.
Scramjets are ramjet engines
in which the air flowing through the engine remains supersonic, hence the name, which stands for ``supersonic combustion ramjet.
The company's concept calls for its space plane to take off horizontally, using a mix of air and liquid hydrogen to power the ramjet engines
