I had a (nother) strange thought this morning. It is my opinion that I have figured out how to do inexpensive compensating nozzles. I don’t have an engine to test the idea. Has anyone ever seen any nozzle testing that used a blank pistol cartridge? My thought is that I could turn a nozzle and firing chamber with pressure gauge for a 22 blank and record the results with a high speed camera. If the exhaust behaves as I predict at high to low pressures, then it might be worth discussing with an engine builder to test on a thrust chamber.
Has anyone heard of such a thing?
Would the results be valid enough to convince real rocket men?
Do any of the real players need a compensating nozzle enough to spend money building one even if it is a valid test concept and is successful?
