winglet
- 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.

- Nota Adicional1
- Winglets are expected to reduce fuel consumption by around 3 percent, reducing CO2 emissions by an equivalent amount.
- Contexto
- This invariably means the resultant force on the winglet, which is usually perpendicular to the surface in the vertical plane and inclined forwards [giving a positive thrust component] in the horizontal plane.
