Ramjet engine

H2—HD and Ar— Ar binary gas mixtures have been measured (34,35). A vortex tube has been used for isotope separation (36), and for the separation of gases in nuclear rocket or ramjet engines.

The inability of the engine to produce a useful propulsive force at zero or low flight speeds necessitates the use of an auxiliary power plant to initially accelerate the vehicle to the required take-over speed of the ramjet. Such auxiliary power is also required for controlled landing of the vehicle. As a consequence the ramjet engine is not well-suited for conventional aircraft applications (with the exception of the helicopter) and the principal application of the engine appears to be further restricted to missiles or other similar vehicles of a one-flight expendable nature ...

Ramjet engines proposed for vehicles designed to explore the atmosphere of the planet Jupiter would use atmospheric hydrogen as the working fluid and add oxygen as fuel for combustion. 

Supersonic combustion ramjet engines for hypersonic vehicles must provide enough distance for fuel to ignite. An ignition delay of 1 millisecond, for a flow moving at 2,000 meters per second, means an ignition distance of 2 meters. 

Special features of self-ignition revealed by high-speed photography, in the mild and transition regimes, behind the attached pressure shocks, were not taken into account while planning an experiment in combustion chambers for ramjet engines.
