Oh I agree the heat is a problem. I am hoping I can push the flame out
from the injector with the annular GOX ring far enough that the fuel
flow and GOX flow will cool it enough.
I was also thinking a plate with many of these injectors might be
interesting since these injectors would have to be pulsed to control
thrust. You would have major issues with vibrations but I think you
could control that with many injectors in patterns.
Some pretty cool side effects like swirl patterns could be produced
ect...
But using a regulator to control GOX flow would be the key way to
control thrust while the O2 sensors maintain A/F ratio.
