A flaperon (a portmanteau of flap and aileron) on an aircraft's wing is a type of control surface that combines the functions of both flaps and ailerons. Some smaller kitplanes have flaperons for reasons of simplicity of manufacture, while some large commercial aircraft such as the Boeing 747 , 767 , 777 , and 787 may have a flaperon between ...
Aileron surface. 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 ...
The flaperon drives are located at the wing roots, an elegant solution that required a large amount of lead for mass balancing the control surfaces to preclude any risk of flutter. Due to this the LS3 wings are heavy, about 85 kg each semi-span (thus the nickname LS-Blei , a pun exploiting the phonetic similarity in the German language between ...
Fairings on the upper wing surface accommodate the tall flaperon bellcranks. The elevator is a carbon / aramid shell except for the LS6-a that employed an Aramid / corrugated paper construction. The fuselage is built as a single shell of glass-reinforced plastic , except in the area of the cockpit that is a double shell for passive safety.
An aircraft with elevons is controlled as though the pilot still has separate aileron and elevator surfaces at their disposal, controlled by the yoke or stick. The inputs of the two controls are mixed either mechanically or electronically to provide the appropriate position for each elevon.
In the absence of an inboard aileron, which provides a gap in many flap installations, a modified flap section may be needed. The thrust gate on the Boeing 757 was provided by a single-slotted flap in between the inboard and outboard double-slotted flaps. [5] The A320, A330, A340 and A380 have no inboard aileron. No thrust gate is required in ...

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]
