Scramjet
A scramjet, short for supersonic combustion ramjet, is a type of jet engine that operates efficiently at hypersonic speeds, typically Mach 5 and above, by compressing incoming air without rotating parts and burning fuel within the supersonic airflow.
TECHNICAL DEFINITION
A scramjet is an air-breathing jet engine designed for hypersonic flight (Mach 5+) that leverages supersonic combustion of fuel within a supersonic airflow, inherently lacking complex rotating machinery like compressors or turbines found in turbojets, instead relying on vehicle speed for ram compression of atmospheric oxygen.
BACKGROUND
A scramjet is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion, but whereas a ramjet decelerates the air to subsonic velocities before combustion using shock cones, a scramjet has no shock cone and slows the airflow using shockwaves produced by its ignition source in place of a shock cone. This allows the scramjet to operate efficiently at extremely high speeds.
