Scram jets

Shut you nasty mouth.

 

You have get it all wrong. You use a turbine to take it up the the speed
then you switch on the scram jets to make go super-sonic. Scram jets are
better than using an after-burner, turbines cannot work with super-sonic
air-flow.

 

What we have here is a credibility gap, of around about Mach 5 if memory
serves me correctly.

 

It was somewhere around Barstow, on the edge of the desert, when the

The credibility gap can be filled with the two-stroke steam engine of
S.Ts design. I'm sure he can Mach 5, no problem.

Jet fighters seem to manage.

 

Super-sonic air flow will destroy the turbine, the air have to be
slowed-down.

And all gas-turbines, even static ones, have internal flows _much_
faster than the speed of sound.

 

They have clever computer controlled spikes and doodads that move
around, so the supersonic air coming in can be slowed and compressed in
the plenum chamber in font of the engine, I think...

There is a chance that the airflow will be supersonic on the suction
side of the compressor blade aerofoils though this can give problems,
not least of which is innefficiency. You have to bear in mind that as
the air is compressed the speed of sound is increased, so allowing for
higher speeds as you move down the compressor without breaking the speed
of sound.

If you look at intake nozzle systems on supersonic aircraft, they are
designed to control the speed of the airflow into the jet.
