How does a scramjet engine work

WebDescription. A ramjet is a variant of an air breathing jet engine that does not include a rotary compressor; rather, it uses the engine's forward motion to compress the incoming air. A ramjet cannot function at zero airspeed and therefore cannot be used to power an aircraft in all phases of flight. A ramjet equipped aircraft requires another ... WebThe scramjet engines would accelerate the plane to as fast as Mach 18 (nearly 12,000 miles per hour). The rockets would kick back in to take the vehicle the rest of the way into orbit.

All scramjet engines have an intake which compresses the incoming air, fuel injectors, a combustion chamber, and a divergent thrust nozzle. Sometimes engines also include a region which acts as a flame holder, although the high stagnation temperatures mean that an area of focused waves may be used, rather than a discrete engine part as seen in turbine engines. Other engines use WebYou have to follow the steps it gives you before enabling the scramjet.
