Leading edge slats....

[Hristo]

Hi all

Wing slats, leading edge slats....whatever they call those things on 109 wings which popped out at high angles of attack and slow speeds.

Can we have that in AH ? I think Jane's ww2 had it

More FLAPS, Hristo ?

Yes!  Leading edge slats!  La-5FN had them too.

In Jane's WWII Fighters, I think only the Me-262 had leading edge slats.  I have read an article in Air & Space Magazine where the Allied pilots had a very hard time flying the captured 262s because they were so advanced.  They had leading edge slats that extended automatically on landing.

Lots of planes had slats- Bf 109, Bf 110, Me 210, Me 410, Me 262, Me 163 had slots, Lagg-3, La-5, La-7, Hampden, J1N1, and probably some others I can't think of now.

As to slats in AH, direct modeling of them is not planned.

Oh yeah, the Swordfish also had them.

How about the sound of slat deploy? At least.

Some pilots says it suddenly open with huge sound when you pulling Bf109 hard.

Eric Brown reported some very annoying handling characteristics because the slats would deploy asymetrically.  He said it was very hard to hold a gunnery solution while turning on the edge of stall.

PYRO said:

Do you mean visually or aerodynamically?

Leading edge slats deploy at high angle of attack and at low speeds. They offer greater stability (once deployed, assymetrical deployment will cause a 'bump') and reduce the onset of a stall. If you do not include them in the flight model then you are handicapping the planes that had them.

sorry for the double post

Pyro:
It just dawned on me: was data collected on flight performance for slats, per se, or was it just incorporated into the overall flight test data?  My hunch would be the later, since it was an automatic mechanism and generally not accessible to pilot control.  So, it might stand to reason that slats are modelled, via the basic flight test data used, making specific slat modelling redundant.

Leonid, I am certain that you are correct.

At least one German pilot remarked that alied evaluation pilots and inexperianced German pilots did not push the 109 far enough to show the value of the slats.
I think that that was in "BF109 at War"

Eric Brown tested the slats fully.

He said gun aiming was impossible when they operated because they would oscillate.  He said this problem also happened when in the slipstream of a bomber during a mock attack.
