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.

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.

它在运输和太空旅行应用领域中，用来取代或补充推进器、轮盘、喷气发动机、固体燃料等。

It serves to replace or complement the propeller, wheel, jet engine, solid fuel, etc, in the area of transportation and use in space travel.
