Krueger flaps deployed from the leading edge of a Boeing 747 (top left and right in photo). 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 ...
The triple-slotted trailing edge flaps are well displayed and the Krueger flaps on the leading edge also are visible. In aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing. The device may be a fixed component, or a movable ...
Krueger flaps are aircraft lift enhancement devices fitted under the leading edge of an aircraft wing where a portion of the lower wing is rotated out in front of the main wing leading edge. Boeing flight tested Krueger flaps on the B-707 prototype on 15 July 1954 and first used Krueger flaps in production for the B-727 maiden flight on 9 ...
Leading edge slats and slots are mounted on the top of the wings' leading edge and while they may be either fixed or retractable, when deployed they provide a slot or gap under the slat to force air against the top of the wing, which is absent on a Krueger flap. They offer excellent lift and enhance controllability at low speeds.
The leading-edge droop flap is a device on the leading edge of aircraft wings designed to improve airflow at high angles of attack. The droop flap is similar to the leading-edge slat and the Krueger flap , but with the difference that the entire leading edge section rotates downwards, whereas the slat and Krueger flap are panels which move away ...
Flap: a hinged aerodynamic surface, usually on the trailing edge, which is rotated downwards to generate extra lift and drag. Variations include plain, slotted, and split flaps. Some, such as Fowler Flaps, also extend rearwards to increase wing area. The Krueger flap is a leading-edge device.

Leading edge slats; Leading edge slots; Krueger flaps; Stall strips; Vortex generators. Associated terms are leading edge radius and leading edge stagnation point. [3] Seen in plan the leading edge may be straight or curved. A straight leading edge may be swept or unswept, the latter meaning that it is perpendicular to the longitudinal axis of ...
