Flameout...

[Fab]

I been doing some arobatic, and found this....

 

Clean plane, go from 350 kts, to vertical, set power to ideal, hold plane in 90 degree climb, til 0 kts, I´m holding it on rudders. As I start to descend backwards, the engine flameout...:cry:

 

Is this normal behaveure for the Mirage or a bug ?:helpsmilie:

In a Su-27 documentary it was said that the Su-27 can do this maneuver while most of the western jet engines would flameout because of the airflow into the engine while descending. So i would guess it is simulated like it should work.

The mirage 2000 can do it, we have movies that prove it...

Then its a bug...

Can you post a link please? Would like to see a Mirage do this. :thumbup:

 

Edit:

Lol, searching on youtube just shows boring airshows with flybys but searching on google brings up an thread on this forum with a link to youtube showing a Mirage doing a tailslide. :lol:

the airflow past the intake/up the exhaust puts the engine at extreme risk of flameout/compressor stall.

Except you have no clue what power setting he's at, which is most likely not idle. At a higher power setting, 85-95% for example, the aircraft will still do this if the T/W is below 1.0, and the engine will still be sucking air at a much higher rate than idle.

 

This also doesn't take into account that you don't know what airspeed he was really at. Airshows play on viewing angles to make normal operations look dangerous.

That is a very good point. I did a couple of tests and the engine is flaming out until you set the throttle to a little bit over 90%. Every throttle position over that and the aircraft will recover from that maneuver on its own with a running engine. According to your mentioned point that we don't know at wich power setting he is this could be a proper simulation and not a bug.
