As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion, the airflow in a scramjet is supersonic. The pulse jet engine works because it uses the dynamic pressure of air for compression. Advantages: Smaller nozzle: The truncated spike can be far smaller than a typical bell nozzle for the same performance, as shown below. The combustion that produces thrust in the ramjet occurs at a subsonic speed in the combustor. It compresses the incoming air by ram pressure, adds the heat energy to velocity and produces thrust.
