winglet
- Sinônimos
- tip fin
- Definição1
- (1) 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. (2) Miniature wing mounted horizontally on fuselage (not at nose or tail), on interplane struts or elsewhere (eg nacelles), often not so much for lift as to carry external load or connect bracing struts or main gears to fuselage.

- An upturned wing tip or small additional vertical aerofoil on a wing tip. The attachment of winglets improved the handling characteristics of the aeroplane.
