Title: Leading edge slats
Post by: Replicant on April 08, 2004, 02:18:27 AM
Forgive me if this has already been covered but I missed the last few updates of AHII.  I noticed that the 109 now has visible leading edge slats but the 110 doesn't.  Will the 110 have them and are there any other aircraft in AH that have leading edge flats fitted?

The 110s, 109F-4, 109G-2,  La7 and La5FN have the audio modelled for the slats.

Right now just the 109E-4, 109G-6 and 109G-10 and the 262 have them visually modelled.

Thats all I can think of right now....

Anyone care to explain the difference in a "slat" and a "slot".

The 163 for instance had a "fixed slot"

Me163 & fiexed slots
http://www.centennialofflight.gov/essay/Theories_of_Flight/Devices/TH17G3.htm

There are two types of slots—fixed and automatic. With the fixed slot, the leading-edge slat is mounted a fixed distance from the airfoil. Its main disadvantage is that it creates excessive drag at high speeds. The German World War II rocket fighter—the Messerschmitt Me-163—had fixed slots in the wing. The automatic slot depends on air pressure lifting the slat away from the wing at high angles of attack to open the slot. At low angles of attack, the slat is flush against the wing leading edge and reduces drag at high speeds compared with the fixed slot. Its main disadvantages are its added weight, complexity, and cost.One main disadvantage of both types of slots is the high stall angle created. The airplane must approach for a landing in an extreme nose-up attitude that reduces visibility.

I wonder if the automatic combat flaps on the N1K2-J will be visually modeled?

A slat is the moving part, a slot may be a fixed slot (opening in the wing's leading edge) or one created by a moving slat.

They just haven't been put into the 3D shapes of all plane that had them yet.  They are in the flight model and  you can hear them deploy on the planes that had them.  That would be the 109s, 110s, 262, and La 5 and La 7.

The first time I flew with them they had to deploy about 10 times before I figured out  what that sound was. I thought I was getting pinged at first and started looking around franticly for the guy shooting at me offline. :)

Will they eventually be a damagable component like the flap / ailerons?

Thank you Pyro.

There are two ways to get angle of attack; one is nose-up attitude, the other is sink rate. Use the latter on approach, the former with your flare.
