Trailing edge flaps extended on the right on a typical airliner (an Airbus A310-300). Leading edge slats are also extended, on the left. A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the ...
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 ...
Cross section of an aerodynamic surface with the trailing edge emphasised An American Aviation AA-1 Yankee being refuelled. Its wing trailing edge can be seen with aileron (deployed downwards) and flap. The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets. [1]
Ailerons are mounted on the trailing edge of each wing near the wingtips and move in opposite directions. When the pilot moves the aileron control to the left, or turns the wheel counter-clockwise, the left aileron goes up and the right aileron goes down. A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the ...
The position of the leading-edge slats on an airliner (Airbus A310-300). In this picture, the slats are drooped. Note also the extended trailing-edge flaps. Slats on the leading edge of an Airbus A318 of Air France Automatic slats of a Messerschmitt Bf 109 The wing of a landing Airbus A319-100.
The Gurney flap (or wickerbill) is a small tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure-side surface of the airfoil [2] and projects 1% to 2% of the wing chord. [3] This trailing edge device can improve the performance of a simple airfoil to nearly the same level as a complex high ...
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.
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 ...
