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.
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 ...
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] Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. [ 2 ]
Flaps are mounted on the trailing edge on the inboard section of each wing (near the wing roots). They are deflected down to increase the effective curvature of the wing. Flaps raise the maximum lift coefficient of the aircraft and therefore reduce its stalling speed. [5]
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 ...
Adaptive Compliant Trailing Edge (ACTE) is a research project on shape-changing flaps for aircraft wings, intended to reduce the aircraft's fuel costs and reduce noise during take-off and landing. It is a join effort by NASA and the U.S. Air Force Research Laboratory [ 1 ] and first airborne tests have been conducted in late 2014.
Blown flaps of the Hunting H.126. Blown flaps, blown wing or jet flaps are powered aerodynamic high-lift devices used on the wings of certain aircraft to improve their low-speed flight characteristics. They use air blown through nozzles to shape the airflow over the rear edge of the wing, directing the flow downward to increase the lift ...
At the leading and trailing edge it consists of much larger taper and smooths out the pressure differences: high pressure at the leading and trailing edge, low pressure on top of the wing and around the fuselage. [10] The flap track fairings on a Boeing 747 Wing tips
