Hi!
I experienced one day a flameout on my Composite Flash with Simjet 3000 as powersourche. Was climbing to an high altitude and went almost straight downwards with throttle in idle position. After the dive I went straight and wanted to put on some thrust and then I saw a white puff and then thin trail of smoke. The engine had stopped and I went around for a landing.
After I had landed I checked the hoppertank and the fueltubing, all with no airbubbels. I tried to start the engine and it came alive as nothing had happened. During the start-up, lage flames came out of the thrusttube. I guess the reason for that was fuel in the pipe after the engine got its flame out. Anyway, the engine performed perfect and I went home for some thinking.
My conclusion is that the engine didnt perform fast enough rpm countdown during my dive, the pump was feeding the engine with the same amount of fuel as it was idling. To much compressed air was pumped into the engine due to late rpm countdown and the flame went out.
Is there someone who has experienced the same situation?
i asume you have a Gaspar Fadec?
read out the last minute and see what happened.
i asume with this cold weather the dive on idle , cooled the engine down.
as soon you throttle up , the engine struggles to cope and flames out.
i never set my engines on idle during flights , i see that if you keep about 25% throttle.
the engine will pickup nicely and very fast.
the residue thrust with 25% is less then 2 kilos.
