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 ...
Some aircraft are equipped with "flaperons", which are more commonly called "inboard ailerons" [citation needed]. These devices function primarily as ailerons, but on some aircraft, will "droop" when the flaps are deployed, thus acting as both a flap and a roll-control inboard aileron.
X-53 Active Aeroelastic Wing in flight. Several technology research and development efforts exist to integrate the functions of aircraft flight control systems such as ailerons, elevators, elevons and flaps into wings to perform the aerodynamic purpose with the advantages of less: mass, cost, drag, inertia (for faster, stronger control response), complexity (mechanically simpler, fewer moving ...
A single surface on each wing serves both purposes: Used as an aileron, the flaperons left and right are actuated differentially; when used as a flap, both flaperons are actuated downwards. When a flaperon is actuated downward (i.e., used as a flap), there is enough freedom of movement left to be able to still use the aileron function.
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 ...

The league's 2025 offseason will kick into gear not too long after the winner of the Kansas City Chiefs vs. Philadelphia Eagles game is crowned champion. The NFL's legal tampering period begins on ...
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 ...
