|Quoting Pihero (Reply 246):|
How is this scenario : aircraft spins around its yaw axis ; one engine goes forward, the other backward ; with the aircraft forward speed reduced, we could well see that engine reverse its flow... it's still provided with a lot of fuel so the engine is on fire from the combustion chambers to the front... of course, it stops turning... you only have a big blow torch which scorched the fan and the nose cone and blistered the paint.
a v2500 fan is spinning at circa 3500-4000 rpm , ( not checked, just guesing) the kenetic energy to slow that down once fuel stops flowing must be a couple of minutes. i have videos of blade failures that takes half that time to slow the fan set and that's damaged big time, fuel cut at failure.
not saying you are wrong cause I am stumped.
i just think the ir reading we have news about came forward of the engine,
