Comparative Study on the Effect of Leading Edge Protuberance of

Unlike other types of flaps, Krueger flaps are mounted on the leading edge of the wing rather than the trailing edge When extended, they create a slot

Extracting the vane out of this slot imposes restrictions on the mechanism design The fixed vanemain flap is only slightly heavier and costlier than the

fixed slot This shows how open the slot is compared to the regular 701 fixed slats, and also how the wing leading edge is sharp, and the slot is much more streamlined

slot vegas Some STOL aircraft in this category are characterized by a fixed slot at the leading edge penalizing parasite drag and flight speed in cruise
