<SU-27> <LOSE CONTROL> <ENGINE SHUTS OFF> <-ve G LOW SPEED>

[KThax]

So this has happened a few times (I also have the video)where when I try to get out of a stall by pushing the stick forward, I lose control of the aircraft and the engine shuts off. The aircrafts then assumes an inverted position with respect to the ground and continues to fall to the ground with any efforts to right it up being futile. The same can be said about restarting the engines.

Is this a vulnerability of the aircraft? If so, does anyone have a means of getting out of this stall?

[Troll Norris]

I am not sure. But always watch your Angle of attack to not exceed critical value, then you will avoid this problem. Engine shuts off bcause there is air surge (engine has not enough air to work properly)

Is there no way to restart them?

[Troll Norris]

No it is not possible until you are in non-critical AoA and negative G.

If you have pressed "S" which disables the computer limiters then its very easy to develop into this situation.

I have not. I'm still new to this aircraft, I found this unrecoverable stall when I was playing the "guns guns guns" quick mission where 2 of us go against four F15s

Let me think it you pressed "S" key and provide the Cobra Manevuer and you pressed the "S" key again but its very late time right?
when you fall i learend the how to slove it! its be like Spin in War thunder but its not easly to provide this and escape stall
1 First needed high alt
2 do not panic or enter the rage mode just relax i know you are in dogfight or video capturing but your angry not slove this problem
3 "know your problem" you watched Pirates of Carriben 3 shaking the boat to drown?
watch this may be you think logically
https://www.youtube.com/watch?v=9La6AXq8yXY
but first watch video before read next texts
4 Up is down/Down is up
you are in a inverted stall this mean your aircraft still flying but inverted pitch control
pull joystick is going down push joystick is going up you need push and pull method for a 15-20 sec after your aircraft is looking down and dive you can control your aircraft
""""""BUT!"""""""
5 Remember!
your engine is dead because motors have dont have enough air for take a breath for this dragon
afther you dive your motors gaining loots of air and your Dragon taking Breath
and your Rmp indicator is raising like first start-up engine
this is mean your dragon's heart beating
6 """"""""""""BECAREFULL!"""""""""""""""
you are a diving like dragon but your motors preparing to roar!
if you make critik manevuers/Hard turn or nose-up immidiately you are enter inverted stall agian
Dive if you want to beat your enemy DİVE! if you love this dragon DİVE!
Dive as you can after engines are on and Roared "İM READY"
now you can breath flame and spit a metals!

if you want a safe Cobra manevuers
throtle is %60-75
Press "S" Key and pull the joystick
when aircraft nose are near to 90 Degree to space
Press "S" key again to close this option
But do not push your joystick forward
you pulled when provide this manevuer if you push you enter the inverted stall
just relase it
now you pulled your
provide this manevuer
just relase its near to 0 degree pull back to handle it
and get Throtle max
you can watch my su-27 Music video

I'll post the link of the video soon then you can see what I did wrong, this is my first time cutting and rendering a video, my first one came out without sound :P
I'll post it here once I fix that.

Thanks for the tips! I think I got what you were trying to say. I was in a dog fight and I did not try to execute a cobra (at least not intentionally) when all I wanted to do was get out of a stall by pushing down on the stick. The plane sort of whiplashed and got stuck in an inverted position.
I'll post the video here soon!

Here it is :P

[Troll Norris]

I just want one note. I think this is possible with real SU-27 because SU-27 Is deliberately unstable (center of lift is in front of the center of gravity) to make it as maneuverable as possible. But If you overdo it, that's what happens.

[Mand'Alor]

i see your problem you stuck at stall best way to evade stall is
Chech speed and make soft manevuers
you allready know its dogfight anything can happen at any moment
Close passes, missle alerts, evade manevuers, shorly everythink can happen
if you enter stall again like this FIRST USE RUDDERS and and then USE AILERONS
im haven'tly enter stall like this but im enter lots of this stall in War thunder With Bf-109
you need perform a Hammer Head Manevuer
this is a defence manevuer but some times best way to evade free-fall stall
plane going trough 90 degree to up when air speed near to take-off speed give full rudder left or right plane turning be like Fast and furious Drift scene
after turn complete Cut throtle to 0 and then give Full throtle for reset Air injection and regain speed quickly

I don't know about that. I'm not an aeronautics engineer :P
What I do know is that the Su-27 is really a fantastic dog fighting plane

Okay I see what you mean, but for that I have to make sure both planes are either the same type (meaning that they both have same rate of climb) or my plane should have higher kinetic speed than the guy behind me.
I think I will try something similar like that today.
Thanks!

No problem you're welcome

Su-27 is deliberately unstable as you said.
