超高速冲压喷气发动机引擎在飞机超过音速的情况下不能启动。
Scramjets engines can not start until the plane flies faster than the speed of sound.
传统的冲压喷气发动机使用液体燃料并与大气中的空气混合燃烧，以提供高速飞行的推力。
Ramjet engines have traditionally used liquid fuel which is mixed with atmospheric air and burned to provide thrust for high-speed flight.
超音速燃烧冲压喷气发动机是利用压缩空气替代常用的涡轮，形成推力的一种喷气发动机。
A scramjet is a type of jet engine that USES compressed air in place of conventional turbines to create thrust. Read "U." S. Developing Jets that Fly Five Times the Speed of Sound.
这里它将达到超音速然后超高速冲压喷气发动机切换成工作状态，迎面气流进入发动机，与燃料混合，混合物在超音速状态流过引擎。
Here it would reach supersonic speeds and then shift to its scramjet engine. The scramjet scoops up air and mixes it with fuel so it burns as the mixture flows through the engine at supersonic speeds.
