scramjets

Airbreathing supersonic engines

Scramjets are jet engines designed to operate at hypersonic speeds—typically above Mach 5.

Unlike conventional jets, scramjets have no moving parts; they use the vehicle's forward motion to compress incoming air, which remains supersonic throughout the engine.

This makes them efficient at extreme speeds but unable to function from a standstill: The scramjet only ignites after a rocket booster accelerates the craft.
