Ramrocket design?

Question

Does anyone have information and details about ramrockets and their design parameters.
Websites, books, homemade, experimenters, etc.

A ramrocket is a rocket connected to a ramjet engine, the rocket exohost is rich IE: not completely combusted and the rammed air adds the required oxygen to complete combustion.

Answer 1

Ram Jets are of relatively easy construction: it is just a tube with a gate inside and some form of plug in the chamber.
It has an input chamber, where the air mixes with the combustible. After this is a partition, with holes that are closed by an elastic membrane, leading to the combustion chamber, where some system ingates the mixture.
Finally, an exhaust pipe, usually designed as ventury pipe.

The air enters one end and mixes with the combustible. The high pressure at the input forces a "valve" to open, and the mixture passes in the combustion chamber, where a "glow-plug" or similar explodes the gas.
The very high pressure in the combustion chamber goes out through the exhaust pipe, but also closes the valve. When the gases are expulsed from the Ventury pipe, the pressure in the combustion chamber is lower than the input chamber, and the cycle restarts.
I have made a few of these rockets in my time, and I could give you a drawing (ACAD R14) or some drawings.
Beware if you make one: they are dangerous when not under control.
Regards.
