When should the wings brake?

[razo+r]

Does anyone have any information of what the max G load is or when the wings should fall off (without damage)?

 

Today, I've turned with a mustang at 550 kph, flaps full down, blackout was slowly coming and suddenly, my left wing fell off... So I'm asking myself, does anyone have informations about that? nothing was in the manual...

Strange, i never lost a wing in the FW, unless you go down with 850+ km/h and pull the stick to hard...

 

But why did you use the flaps? These aren't combat flaps...

true, those aren't combat flaps, but I use them to keep up turning with the mustangs (and loose speed)

Were you rolling while pulling? Rolling increases the G-load of the rising wing, which can make that wing go from "almost at G-limit" to "over G-limit."

And flap configurations can also affect structural limitations...

[Echo38]

Right—if nothing else, flaps = more lift = more G-forces, at a given speed.

at the time i started to pull, I was not rolling

Well, that is what i'm asking for, we kind off now the g limit for the mustang and the spitfire, but since we rarely brake wings in german planes, i'd like to know what the limit would be

Just tested again in SP:

 

550 kph, full flaps down and a bank like i did and pulled harder on the stick than I did when the wing fell off. Surprisingly, this time, the wing did not fall off, and in outside view, the Gs were at 5.9...

 

looks like either it's random or like in the F-5, the damage will come after some time...

[Echo38]

Very little is random in DCS. Accumulated stress damage seems more plausible.

Would be very nice to hear something more about this, especially from devs, I was not aware of anything like this...

[NineLine]

I talk to Yo-Yo about this, there is indeed accumulative damage to the wings, the strength decreases depending on the amount of excessive force place on the wing.

[coopes]

what do you expect with full flaps at that speed. Think of the pressure under the wings.

 

There is a reason aircraft are given speed limits at different angles of flap. Have you noticed the more Degree of flap used the slower the airspeed.

[LeCuvier]

Quite normal for a metal structure. The stress level it can withstand depends on other variables like duration, and the dynamics of the stress. So if the stress has an element of vibration or rapid load change, the structure weakens more rapidly.

Ok, thanks for that

I got the wings to break on the P-51 today... oops
