Turbulence when flying through vortices of air of another plane

Is there a reason for it not be „modelled“ in MP? If I can fly through smoke of an aircraft, why not through propwash?

 

As far as I remember - I think Han replied in the old questions to developers thread - it puts even more of a strain on the net-code.

Ah, ok. Didn't know that.

I don't think there is wake turbulence modelled in the game.  Prop wash is certainly modelled in single-player.

 

 

 
This appears to be just a headshake effect without the turbulence. Does it show up with head shake unticked / in replays in ALT+F2?

Its not a head shake effect.

Well, this is how hard Wing Vortices can hit, even from a 6.5ton Aircraft. 

 

There was a Civil Aviation Accident in France with a 1 ton Dr.400 and an An-2, in which the Dr.400 simply got flipped over on Take-Off killing all 4 on Board. They Recreated in a Controlled Manner. It's quite astonishing to see. 

 

 

 

It was actually an accident in Germany (hence BFU's Involvement - had the accident happened in France, it would have been under the jurisdiction of BEA).

 

What one should keep in mind is that wake-vortices are mainly dependant on Cl (Ca in German) and hence are strongest at high AoA and large flap-travel (lots of spanwise flow and downwash created, hence lots of vorticity Curling around the wing-tips).

At higher Speeds (hence lower Cl values), while still not insignificant, the effect of wake-vortices is less dramatic.

That doesn't mean that larger aircraft can't turn you upside down (see this accident: http://avherald.com/h?article=4a5e80f3) but recovery usually isn't in jeopady as there is lots of altitude for recovery.

See this Video for the effect of wake-vortices on similarly-sized aircraft (727 and 737) in or close to cruise-configuration:

 

This study was done in the aftermath of USAir 427, where a 737 went out of Control, following a 727 in config flaps 1 below 190KIAS. It was later shown that wake-vortices played (if any) a minor role and the crash was due to a rudder PCU shuttle-valve jamming in "full"-condition, nose-slicing the 737 out of control. It was later determined that Flaps 1 and 190 KIAS was the "crossover Speed" at this particular weight - that means that the rudder becomes more powerful in Controlling roll than the ailerons below that airspeeds (it's actually an AoA, but that's another story).

 

Keep in mind this is just for staying inside the vortex-core. If headings are substantially different and transit-times through the Vortex are short, there's just a jolt and you're out of it before you kne what happened.

 

Propeller-wake is different. It's more of a "broadband" turbulent airstream, that is mostly just annoying and less dangerous per se.

Any idea if the devs plan or have improved the code to be able to add vortices which affect you flight if you pass thru them?

Some guys say its implemented in game, I say absolutely not, not even close, I have experienced prop wash in real life during simulated dogfights , it moves you around pretty bad and for some seconds your controls feel very mushy.

 

Hope gets implemented, would be a game changer and different approach to dogfighting techniques.

No more saddling up but slashing attacks instead, just like in the real thing.

I tried the other simulator the other day with WW2 birds and noticed the turbulence. Instantly, I knew I had to change the direction of attack other than dead six or be slightly above. I liked it! Hopefully someday it will make it into IL2.?

I have a feeling that is them causing an accelerated stall due to AOA trying to get the shot. It is definitely not in the game.
