Re: Pressure Gain Combustion (Now Proven)

I've also been thinking about using a pressure-jet injector system in front of the inlet of a valveless PJ. In fact Eric has already been doing something like that but inside the inlet and without the heating of the fuel:

What will happen then is that the PJ can breathe in through the inlets but cannot (or hardly) breathe out through the inlets, which will increase the combustion pressure. Thus higher thermal efficiency.
Of course it also allows the PJ to have some kind of resistance at the exhaust, as long as that "resistance" (for example a turbine) doesn't desturb the accoustics.
It seems however that a pressure jet injection system isn't using all the available energy (I don't mean the chemical energy)in the fuel stream, but can be upgraded with some kind of device making the injection system's ejectors much more efficient
Which device? Don't say yet Has H and S in it. O.k. the quiz has started
