stray cat Posted September 17, 2014 Share Posted September 17, 2014 How to not blow my engine in midflight? So far I had my engine shut off in 3 flights after being on full thrust and afterburner for about 2 minutes. I did not pull any intense G maneuvers. On another flight I was able to avoid this. Is there something important on cold start one can mess up to cause these shutdowns? Because the flights where I started in the air, I never got an engine shut. Also how to restart the engine in flight if that happens? The engine shutdown shows the 2 compressor needles being at 20 on the gauge, not moving or reacting to thrust changes.

159th_Viper Posted September 17, 2014 Share Posted September 17, 2014 You sure you did not run out of fuel? Why are you running afterburner for two minutes?

Cobra847 Posted September 17, 2014 Share Posted September 17, 2014 Make sure you avoid 0G. (common error) EDIT: please post a track as Viper noted if the issue persists. Perhaps there is an error in engine stress. Nicholas Dackard Founder & Lead Artist Heatblur Simulations https://www.facebook.com/heatblur/ Link to comment Share on other sites More sharing options...
AndyHill Posted September 17, 2014 Share Posted September 17, 2014 One of the things I've been hoping for for a while is a debriefing addition for DCS that would show you what went wrong if a mechanical failure occurred for one reason or another.

stray cat Posted September 17, 2014 Author Share Posted September 17, 2014 By 0G you mean avoiding zero G forces? Would that happen on the tip of flying a parable? Where can I find single player replays? I did not save it manually. Link to comment Share on other sites More sharing options...
xxJohnxx Posted September 17, 2014 Share Posted September 17, 2014 The Mig has feeder tanks for negative g situations, that also can feed the engines in 0g conditions. However, feeder tank capacity is quit small, and especially arround 0g not all of it might be usable. Thefore, if you have high fuel flow because you are running on after burner, you might starve your engine off fuel in a few seconds of 0g flight.

joey45 Posted September 17, 2014 Share Posted September 17, 2014 Don't use reheat for more then 30 seconds. The only way to make sense out of change is to plunge into it, move with it, and join the dance.

Tango Posted September 18, 2014 Share Posted September 18, 2014 Don't use reheat for more then 30 seconds. I burned through whole tanks of gas in reheat without issue. Nothing melted, nothing broken. Maybe if you get slow it could be an issue?? Best regards, Tango. Link to comment Share on other sites More sharing options...
mvsgas Posted September 18, 2014 Share Posted September 18, 2014 This might answer the OP From the manual 20. Negative g-loads may be developed for not longer than: (a) 15 s at non-reheat engine settings; (b) 5 s at reheat settings; © 3 s at second reheat setting. 21. Flight with g-loads approximating zero (±0.2 g) should not last for longer than 1 -2 s. WARNING Negative or near-zero g-load flight is allowed provided the tanks contain at least 500 L of fuel 22. Repeated application of negative or near-zero g-load is allowed only after at least 30 s flying at positive g-load. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true.. Link to comment Share on other sites More sharing options...
159th_Viper Posted September 18, 2014 Share Posted September 18, 2014 Where can I find single player replays? I did not save it manually. In that case you do not.

Tango Posted September 18, 2014 Share Posted September 18, 2014 (edited) I know very little about flying fast jets or how they work. What scenarios would the use of afterburners come in to play ? Any time you need the additional thrust. Just be aware of: * Airflow (due to airspeed) * AoA vs. airspeed * be careful making rapid thrust changes (e.g. max afterburner to idle - take it out of burner, then slowly reduce power to prevent surging) I already caused an inlet surge on my first flight and it goes POP pretty darn loudly. Awesome feature. I was flying the aircraft in ways it should not be flown though... :pilotfly: If you look in external view, reducing power causes the spill doors on the side of the nose cone to open. 8) Best regards, Tango.

lmp Posted September 18, 2014 Share Posted September 18, 2014 Also, if you put this thing in reheat, you can almost see the fuel needle move towards empty. At one point I had 2000kg of fuel left after an intercept, so I decided to burn some before landing. I did one biggish circuit in afterburner and I was down almost to 1000kg. And I wasn't even using the emergency reheat mode. Link to comment Share on other sites More sharing options...

I think the fuel gauge is in liters, not kg. All the fuel warning lights are liters based. Best regards, Tango.

In any case, I had 2000 somethings out of the less than 3000 somethings that fit in the tank, and went down to 1000 somethings ;). Seriously though, I'll look it up in the manual.

Aginor Posted September 18, 2014 Share Posted September 18, 2014 The speed at which this things gulps down fuel reminds me of my time in the military, if you get my drift. :D Really magnificient! And while we're talking about dumping fuel: Is there an actual lever to do that? Or do I just use my afterburner to burn excess fuel before landing? :D DCSW weapons cheat sheet speed cheat sheet Link to comment Share on other sites More sharing options...

Aginor Posted September 18, 2014 Share Posted September 18, 2014 I lost my engine in a tailspin during my most recent flight. Exciting! I plunged 20,000 ft. and blacked out twice before I could recover. Then I noticed the engine had failed during the spin. I hit the emergency restart switch and prayed, just 2,000 ft. above the ground. And it restarted! I didn't make the landing without damage though. Had a bit too much vertical velocity and the left main gear got damaged. DCSW weapons cheat sheet speed cheat sheet Link to comment Share on other sites More sharing options...
