Vat is zat zuppozed to mean?
:D

Anyway, there was another slat thread thatturned into a flamefest. Because of some issues I called Gunther Rall and directly asked him about the good and bad sides.
Tha bad sides are mentioned on the website linked in the beginning of this thread, - how he put it was simply that "in a rough turn a slat would come out and the aircraft would snap-stall" It was the outboard slat.
He said he did not prefer them in combat, but without them as a contrary, landing speed would have been unacceptably high.
I asked a former LW wingco about them. He told me that the F4's (Phantom) did have some problems with them, and they had caused some disintergrations (!). Now the tendency was more to use manually controlled slats in the new designs, if any at all.
Thoughts?

Agh? PanzerIV and Wes14 thought the 163 had slats but then if you don't read the whole thread...... Oh well.

I didn't answer Serenity because he would get more info by using Google.

Anyways, the slats were used by the Swordfish to get the slowest landing speed, from an already slow a/c, hense the comment 'for some reason'. Doesn't take a genious to understand the comment.

I was asking for documentation as to the German slats being copies of handley-paige slats. Now, how would one type that into google? It makes more sense to simply ask you for your documentation. Its not that I dont believe you, I just dont recall having heard that before.

Gee Serenity, the first link when I Googled came up with a reference to H-P slats on the 109.:eek:

http://freespace.virgin.net/john.dell/bf109/Bf109Story.htm

Here is another link, http://www.virtualpilots.fi/feature/articles/109myths/

You needed to be more specific for it is common knowledge that the 109 used H-P slats so thought you were asking about the Swordfish.

I think there are no manually controlled slats nowadays. They are all computer controlled in faster or fixed in slow aircrafts.

Although hogging quite a bit of top speed many countries where F4 was exported preferred the slats because F4 had a tendency for nasty uncontrolled departures in high Gs without slats.

PS. Thanks for nice pictures Milo. I've never seen those before.

What gives you that idea? There are several light STOL aircraft with aerodynamically actuated slats. Like this CH 701 (also note the Junker-type flaperons):




American Hombuilts:


Savannah:



Yuma:

German slats were not COPIES of Handley-Page slats. They WERE Handley-Page slats. That the beauty of licences :)

CH 701 and its "copies" have fixed slats (very clearly seen from the picture of the Savannah you posted). Mr. Heinz has a very nice (allthough not pretty) design in the CH 701 which *influence* can be clearly seen in planes like the Savannah and Yuma.

Ah funny coincidence. I was working on some stuff by an Italian Messerschmitt 109 pilot and heh, of his impressions about the 109...

"Another important aspect of the German plane was the Handley-Page slats which allowed very tight turns."

Made in Germany I bet, and no fees payed.
I think it was originally a German invention that Handley-page however put to used and got a license for.
