What's the magic angle for the fronterons or leading edge slats?
Try looking at the angles on the F-18 (V4, V5, both?) as a starting point.
For TRAILING edge deflections (all number are approximate):
<15 degrees - Lots of additional lift/modest additional drag.
15 - 30 degrees - some additional lift/some additional drag.
>30 degrees - modest additional lift/lots of additional drag.
The leading edge slats on the RCP F-18 V4 are about 30 Deg, and the leading edge slats on the RCP SU-27 V5 are about 35 Deg.
Anyone made them adjustable?
Hooked up servos etc?
I like 22-25 degrees for a good mix of speed and lift. On our FRCFoamies f18 and F22 we're at 22 degrees. On the Highlander I linked the flaps with the slats on the front and it was magical! But the RCP f18 really flew well at a higher angle. I also did the SU27 with the 22 degre flaps and it was reallt amazing!
Thanks Greg, I will be adding my 1/2 inch 22 degree flaps on my Eurofighter.
After looking at Jay's Euro V5, it looks more like 40mm tapering down to 25mm at the wing tip.
First attempt at a Euro v5 with leading edge flaps. The flap design was ripped off Jay's Mig2.88. Bare airframe comes in at 99 grams.
