Elefant1301 Posted March 24, 2015 Share Posted March 24, 2015 Hi, Maybe I am missing something but I recently noticed that the engine kept shutting off after having used the afterburners (when the throttle is back to full dry). I don't remember it behaved this way before... It is during a custom mission, aircraft armed with RN-28, 4 missiles and SPRD-99 (jettisoned after the take-off). Did I forget something ? :suspect::suspect: Link to comment Share on other sites More sharing options...
Badger1-1 Posted March 24, 2015 Share Posted March 24, 2015 Maybe too much negative Gs? Link to comment Share on other sites More sharing options...

yunan4 Posted March 24, 2015 Share Posted March 24, 2015 I recall reading in the manual somewhere that sudden throttle changes at certain altitudes especially when throttling down out of burners could lead to a engine failure. Link to comment Share on other sites More sharing options...
Einherjer Posted March 24, 2015 Share Posted March 24, 2015 I have the same thing since the FM update. Often on bombing runs, when I go buster to the target -> whoosh, engine spools down. That makes the situation a little bit hairy, dropping ordnance, evade AAA and reignite the engine :) Link to comment Share on other sites More sharing options...
Derbysieger Posted March 24, 2015 Share Posted March 24, 2015 It would be easier to help if you would post a track. I didn't run into this problem (yet) and I flew the MiG quite a bit yesterday including some Air-Ground with rockets.

WinterH Posted March 24, 2015 Share Posted March 24, 2015 You may be overspeeding. Wishlist: F-4E Block 53 +, MiG-27K, Su-17M3 or M4, AH-1F or W circa 80s or early 90s, J35 Draken, Kfir C7, Mirage III/V DCS-Dismounts Script Link to comment Share on other sites More sharing options...
Einherjer Posted March 24, 2015 Share Posted March 24, 2015 You may be overspeeding. I think so too! Don't get me wrong, I don't think it's an issue, it's just new ;) and I have to watch my IAS Link to comment Share on other sites More sharing options...
Elefant1301 Posted March 24, 2015 Author Share Posted March 24, 2015 Here is the track. You'll notice two shut off, one at high speed and the other one at about 700 kph IAS if I remember well. Please do not comment on the choice of the target, it was just a training on a ghost town...:lol: The first shut off happens after the atomic raid when intercepting the lonely S3 and the second one after the S3 gets destroyed by two RS missiles.atomic_bomb.trk Link to comment Share on other sites More sharing options...
Toxic Posted March 24, 2015 Share Posted March 24, 2015 You may be overspeeding. I believe it's overspeeding the engine. If you're on a bombing sortie and go from 5,000meters to 1,000 meters in a matter of a few sec. in buster you're probably going to overspeed it. :) #CHOPPERLIVESMATTER http://www.aircombatgroup.co.uk/ [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Elefant1301 Posted March 24, 2015 Author Share Posted March 24, 2015 You'll see, if you use the track file, that I wasn't overspeeding the engine during the second shut off. Link to comment Share on other sites More sharing options...

skendzie Posted March 26, 2015 Share Posted March 26, 2015 I just bought this module two days ago so I'm still very new to the Mig-21. But I keep experiencing flameouts too. I don't think I'm overspeeding or making to many extreme maneuvers but I could be wrong. I hope someone can answer OP's question. Maybe I slow down too fast...

iFoxRomeo Posted March 29, 2015 Share Posted March 29, 2015 Elefant, the first flameout was because of overspeed. Not engine overspeed but IAS overspeed. At nearly 1400km/h IAS the flameout happened. 1300km/h is the limit. With the current FM, your alarmbells should ring whenever the nosecone goes beyond 40% at high speed. You had it at 50% at the moment of the flameout. The second flameout was because of G near 0. You were at +/-0G for approx. 5 seconds when the flameout occured. So everything is fine with the MiG-21.
