High speed, air-breathing engines are known as ramjets or scramjets because they ram oxygen into the front of the engines.
As air-breathing engines, scramjets have significantly fewer moving parts than traditional turbojet engines, and do not require oxidizer to be carried onboard for combustion like conventional rocket engines do.
