Another look at partial wing damage?

[JaffaCake]

I tried to do a bit of testing on this, by getting the tip of the wing of my IL2 shot off by either BK3.7 or ram by a friendly aircraft.

 

My observations post-effect is that it appears to be hard-scripted condition on the aircraft:

- There is some aileron control available to sustain the aircraft in flight and flight with partial wing is possible with IL2 at least. Overall flight is stable with one exception:

-  There appears to be randomly occurring approx. 45 degree sudden rolls that affect the aircraft. These rolls are not induced by my controls, and an otherwise stable aircraft would just haphazardly randomly roll 45 either to the left or right (irrespective of the damaged wing).

- Generally you do not have to apply a lot of aileron to "compensate" for the missing wing, but also aileron authority goes down significantly. (feels weird to me?)

 

The flight would be possible long-term if these random large rolls were not present.

I have 2 guesses as to what may be causing this:

- "Phantom" aileron on the destroyed part of the wing acting as "disconnected" and fluttering, inducing these rolls as a result

- The low-level turbulence is simulated by applying random forces to the aircraft. These forces are then exaggerated by the missing wing chunk, even at "stable" speeds. 

 

What I still want to test:

- Flight with both wings partially missing (need to find an aircraft where the DM separates wing tip before aileron)

- Look deeper into aileron authority and position when the wing is missing - the fact that you barely need ~10% input to keep level (barring the crazy random rolls) is weird to me.

 

 

 

Honestly at this stage the resulting FM from the missing wing just feels a little too wrong an unnatural? Especially when compared to heavily damaged but intact wing, where nearly 100% aileron input is required to keep level, with both ailerons operational.
