I've been reading about the early rocket work during WW2. They tried all sorts of fuels, hydrogen peroxide, hydrazine, red fuming nitric acid...
Just in the scope of JATO/RATO, has there ever been one working just with kerosene? The airplane would accelerate normally to sufficient airspeed such that enough oxygen was flowing, then the JATO would ignite. This would then boost the aircraft very rapidly up to a high altitude.
I think this could be called an afterburner all by itself (without the turbojet lol), or maybe even a ramjet all by itself. Whatever you call it, it has no moving parts other than a fuel pump. So I am wondering if this concept was ever tried during WW2 or shortly thereafter.
(P.S., surprised there is not JATO tag, nor RATO tag. I will create it but also use "takeoff" for visibility purposes.)
