Ramjet 2

I'm wrote about this yesterday.

When air is get in path, air is compressed.

Ramjet is used sound velocity, so air is already compressed. then inside of the Ramjet

occur success shock wave.

Ramjet is not usually use to plane.

Most plane using turbo engine.

First using ramjet plane is Leduc, designed by Leduc , French.

Leduc is not fighter, it is common plane.

But Leuc is fall in the ground. inventor doesn't knew why.

They had experiment, twice of experiment are failed. So Third plane is go to the museum had no experiment.

And their test is end because lack of budget.


PS. What is the fastest fighter in the world.

Answer is SR-71.  

It is not using now a day.
