I have, but that video has an error: it's not a hybrid rocket engine because a rocket by definition contains all of it's reaction mass. Meanwhile both a turbine and a scramjet use oxygen from the air which gets incorporated into the carbon dioxide and water molecules which fly out the exhaust nozzle to give the aircraft thrust.

Tell us more.

A rocket would have two tanks: one would be a fuel tank carrying either hydrogen or kerosene while the other would contain the oxygen used to burn it.

A jet (whether it's a turbine or a ramjet) would only have a fuel tanks filled with kerosene and it would get the oxygen to burn it from the surrounding air.

A turbine engine uses the superheated gases used to provide thrust to turn a turbine at the front which sucks in the air (and oxygen) used to burn the fuel:


A ramjet uses the forward motion of the aircraft to push air into the engine to burn the fuel:


You can achieve higher speeds with a ramjet but you can't start it from a dead stop. A combined cycle has two reactors for each inlet. At lower speeds (less than Mach 3), the air will be directed to the turbine reactor while at speeds between Mach 3 and Mach 6, it will be directed to the ramjet:

So the turbo is sitting atop the ramjet? It's a simple engine, eh? Kerosene. So, does it use a gradually decreasing outlet in order to create more force like with liquid? Or does it not need this with concern to it being heated air?

[Ad_Quid_Orator]

All the exhaust would be in the form of gas when it leaves the engine.

I am looking forward to seeing g the new F-47 but this is pretty amazing

[Dongie]

I saw one on it as well. No pilot needed. It looks as tho it has anti gravity the way it moves.

[Surely]

At that speed. Seems like it could reach the space station!
