My first plan is to maybe taper the flame tube so it funnels the gas into the turbine. If that doesn't reduce the surge, then I may put a bleed valve in the combustor to bleed some of the pressure before the turbine section.
On a related note, my afterburner is almost done and will undergo testing soon!
So it appears that 17 psi at 102,000 rpm stalls the compressor blades. Is your plan to reduce the backpressure in the burner and associated plumbing? I have heard of people trimming the turbine blades to reduce backpressure and get the compressor up to higher rpms where it can handle more pressure.
