How does a scramjet engine work
In: 2
The air is pushed into the engine just from the engine moving forwards at high speed, that’s why it only works at high speeds at all.
The inside of the engine gets narrower, which causes the rushing in air to be slowed down and compressed. In turbojet engines the compression is done with compressors, the giant fan you see in the front is a part of that. Into the compressed air fuel is injected, which causes it to expand and get pushed out the back, just like with turbojet engines.
