- Like the comparatively slower ramjet counterpart, the scramjet has a simple mechanical design with no moving parts.
- Here scramjets beat the speed of sound using the Pegasus rocket, which later separates from the vehicle.
- The advantages of the technology are clear: the scramjet contains relatively few moving parts compared to a conventional turbine jet engine.
Origin 1960s: from s(upersonic) + c(ombustion) + ramjet.
