English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
DEF

An upturned wingtip or added auxiliary aerofoil(s) above and/or below tip to increase efficiency of wing in cruise, usually by reducing tip vortex and thus recovering energy lost therein and improving circulation and lift of outer portion of wing.

CONT

The tipsails are an extension of NASA [National Aeronautics and Space Administration] technology which led to the application of small winglets on many airplanes ... Tipsails operate in the rotational flow field of the wing tip vortex, giving an effect similar to the sail of a boat as it moves into the wind. The force vector produced by the pressure differential between the two surfaces is directed forward, which results in a cruise drag reduction. Rudders, located at the trailing edge of the tipsails, provide directional control without requiring a special surface dedicated solely to that purpose.
