109 wing slats - how are they actuated?
« on: July 19, 2007, 10:44:10 PM »
i've looked around on google and such but i cant really figure out HOW they are pushed in and out all the time mechanically...

somone told me the wind pushes them back into the wing but when the chord line or 'aoa' reaches a sertain amount they pop out

they're actually very simple.............when the plane accelerates, and positive airflow is achieved over the wing, the presure forces them back into their slots...this is where they stay, as long as the pilot doesn't stall a wing. once a wing stalls, there's actually negative airpressure at the leading edge, thus allowing the slats to drop out. if you noticed the curverature to them, they actually increas the wing's camber, and i think they also slightly increase the wing'sarea too.....both of which help that wing to produce lift. :D :aok

pretty ingenious bastages they had back then, eh??:aok

Yes the Handley-Page slats on the 109 were ingenious.

The Faery Swordfish had them as well, for some reason.

The slats on the 109 and other German types were Handley-Page style slats.  Guess why? Because they were Handley Page patent and the British company was paid royalties for every single fighter and other plane Germany built that used the slats.

Of course, British planes used the slats too. And Russian. La-5 series for example. And Japanese. Surely in many US types too, for example F-86 Sabre had identical slats to 109. Who knows, maybe even Italians too. And slats are used in every modern airliner and fighter, though these days automatically.

They don't actually always come out all at once with a loud sound but it is also possible that they move slightly out and in in slow level flight. I didn't know this until I saw it in in-flight video of Black 6. So their operation does not rely only on AoA but also of speed.

Documentation on what?


The 163 had a fixed slot.

This has bothered me for a long time. There are several photos where the slats are shown open while the plane is on ground and people tend to believe that "open" is some kind of neutral position and only speed forces the shut.

AFAIK, the slats have no springs or such, but they move freely. Therefore they could just as well be in shut position already before take-off. It is the airflow and AoA that forces them open. The photos with open slat on ground are, I believe, because of mechanicians just checking their movement or something after landing.

It seems a bit funny that in game the slat are always open when the plane is on ground....

Someone, please correct or verify this :)

The slats on the swordfish upper wing are easy to see - just google some pictures of the swordfish.  I do believe (remember reading it someplace) that the swordfish slats were different than the 109s in that the pilot could lock them in position - perhaps necessary when the wings were folded for storage?
