Ramjet

Ramjet is one of the jet engine.

Ramjet doesn't has turbine inside body. It is using compression of the air.

So It can't take off oneself.

When It take off, It is need to help other devices help to fly.

It is designed to high speed than sound velocity or equal.

Ramjet is usually used fighter, space vehicle etc.


Ramjet Theory

 I told you Ramjet is design for high speed.

When object is get in the sound velocity, there is shock wave It's caused by compressed air and accompanied sonic boom.

Compressed air inlet that narrow path and compressed again in there.

High compressed air has high heat because molecular be bumped each other.

Then fuel jet into air. Baaaaam
