Krueger flaps are suitable as high lift devices for NLF, because they leave the upper wing surface clean when retracted. Furthermore, when fully deployed during take-off and landing, the main Krueger panels form a kind of deflector that protects the fixed leading edge from accumulation of insects or dirt and from surface erosion due to rain or hail during low-altitude flights.
Krueger Flaps are installed on the leading edge of the aircraft, unlike other flaps which are present on the trailing edge. The total chord length of the wing is increased when Krueger flaps are deployed. Wings get a new leading edge when the Krueger flaps are deployed.

New project's animation Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike slats or droop flaps, the main wing upper surface and its nose is not changed. Instead, a portion of the lower wing is rotated out in front of the main wing leading edge. C Krueger flap were performed experimentally. The model consisted of a rectangular wing of 0.6 m chord and of 1.2 m span with circular endplates.

Krueger flap - Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Krueger flaps are leading edge high-lift devices needed to increase the critical angle of attach at low speed flight phases and hence delay the onset of stall (sudden loss of lift force). They are particularly well suited for NLF wings since they deploy from the lower part of the wing, leaving the upper part smooth to facilitate NLF, as opposed to traditional slats used on most aircraft today.
Instead, a portion of the lower wing is rotated out in front of the main wing leading edge.

When the flap is retracted, the folding nose section rotates and is stored under the wing. The LE flaps do not have anti-ice. 737-200 Basic Krueger Flaps.
