The Boeing 747-8 with four General Electric GEnx-2B67 turbofans - with carbon fan & fan case, raked wingtip, gapped configuration Krueger flaps, Greetings airlines, ✈ Here you see Krueger Flaps from a B747-8 Variable Camber. We have full capability to perform all CMM repairs including LSA repairs. Time lapse departing Incheon in a Korean Air 747-8 ✈️ . Fun to watch the leading edge Krueger flaps retract. Aerodynamic condensation can be seen over gapped configuration Krueger flaps, double-slotted flaps, and supercritical wing - some of the items that differ extensively from the -400. Very nice aircraft.

The Krueger flaps developed for the Boeing 747 were constructed from fiberglass honeycomb material and were designed to be intentionally distorted into an aerofoil section on deployment. History. Krüger flaps were invented by Werner Krüger in 1943 and evaluated in the wind tunnels in Göttingen, Germany.

The untwisted wing incorporated a full-span, leading-edge Krueger flap and a full-span, single-slotted trailing-edge flap. The trailing-edge flap was tested at a
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.
These included Krueger flaps running almost the entire length of the wings leading edge, as well as complex three-part slotted flaps along the trailing edge of the wing. A Krueger flap was installed along the leading edge between the inner and
Krueger flap is similar to these topics: Leading-edge slat, Airplane, Circulation control wing and more. EXTEND THE KRUEGER FLAP IT WILL CAUSE THE AILERON TO DROOP BY 10 DEGREES. NOTE: If the position of the slats is 15 deg. or greater, the Krueger flaps will already be extended.

Current Boeing aircraft, and many others, use this design between the fuselage and closest Krueger flaps, hinged at their leading edges, extend forwards from the under surface of the wing, increasing the wing camber and maximum co-efficient of lift. Conversely, slats extend outwards from the leading edge.
Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Airfoil Lift (force) Lift-to-drag ratio Hydrofoil Aerodynamic force Boeing
The wing root Krueger flap deploys with the leading edge slats and is either fully deployed or fully retracted. There are two hydraulic actuators – a small one to deploy the notch flap laterally (and retract it) and the main actuator to move the main Krueger flap. A series of links and drive shafts unfolds and deploys the flap.

To put it simply, flaps increase the camber (and sometimes the area) of your wing. By increasing the camber of your wing, you also increase the amount of lift your wing can produce. With flaps down, your wing can produce more lift at slower speeds, than when your flaps are retracted. Using flaps gives you three distinct advantages in your plane:
Thanks to Mark Bland for letting us share them here. The Krueger flap is somewhat less effective than the slat but is probably simpler in mechanical design. Some aircraft employ slats on the outboard portion of the leading edge, where more powerful flow control is required, and Krueger flaps on the inboard portion of the leading edge. De kruegerflap is genoemd naar de Duitse ingenieur Werner Krueger die hem in 1943 uitvond.

Krueger flaps are positioned on the leading edge of the wings and are used on many jet airliners. The Fowler, Fairey-Youngman and Gouge types of flap increase the wing area in addition to changing the camber. The larger lifting surface reduces wing loading, hence further reducing the stalling speed. Some flaps are fitted elsewhere.

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. The Krueger flaps developed for the Boeing 747 were constructed from fiberglass honeycomb material and were designed to be intentionally distorted into an aerofoil section on deployment. History. Krüger flaps were invented by Werner Krüger in 1943 and evaluated in the wind tunnels in Göttingen, Germany.
