The wingtip vortex, which rotates around from below the wing, strikes the cambered surface of the winglet, generating a force that angles inward and slightly forward,. The winglet converts some of the wasted energy in the wingtip vortex to an apparent thrust.Another potential benefit of winglets is that they reduce the strength of wingtip vortices.

What else can I help you with?
Why do airplanes have winglets?
Winglets increase the fuel efficiency of aircraft that have them.
What is the purpose of winglets?
Winglets increase an aircraft's operating efficiency by reducing induced drag at the tips of the wings
How do winglets on an airplane help it save fuel and decrease the amount of turbulece?
The winglets work by reducing drag created by the vortices that are generated by a plane's wingtips. Aviation Partners Boeing estimates that its blended winglets for the 767-300ER will save up to 6.5 percent on fuel consumption, or a savings of roughly 500,000 gallons of jet fuel per aircraft per year for operators with the longest average sector lengths and highest aircraft utilization rates.
Do planes need winglets?
Winglets are not absolutely required but many planes have winglets added to improve the aerodymanic efficiency of the wing.
Why doesn't Antonov add winglets to their heavy cargo planes such as An-225 and An-124 to reduce induced drag?
I can't think of any cathedral-wing aircraft that DO use winglets. Spanwise flow on a cathedral wing would be flowing 'uphill' (inward) and would be interrupted by the fuselage.
Why are the ends of some airplane wings pointed up?
They are called winglets. They can help reduce drag on aircraft performance resulting in performance improvements of typically 5%.
How do you distinguish between an Airbus and a Boeing?
Generally airbus has engines which go under the wing, where Boeing tend to mount them forward of the wing Airbus aircraft appear to be quite 'stalky' standing on their landing gear, like some sort of wading bird, and the nose is more blunt looking than Boeing aircraft. Depending on the operator, many Airbus aircraft have winglets on the wing tips also. An easy to spot difference are the cockpit windows, and most Airbus aircraft have wingtip "fences" at the end of the wing, while Boeing uses winglets, or sometimes "raked wingtips."
Why does Airbus use winglets?
to reduce drag
Why are winglets put on a planes airfoil?
Winglets are fitted to the tips of aircraft wings to increase the lift efficiency of the wing. As the airflow passes over the wing shape, the air going over the top of the wing has further to travel. The air flowing over the wing near the the fuselage body up to about 3quarters of the way towards the tip of the wing has to travel up and over the wing, thus creating the lift. Air, as with water will choose the path of least resistance, so airflow near the wing tip starts to go over the top of the wing but then" slips off " to the side meaning that the end section of the wing produces little or no lift. The winglets are there to stop the slipping off effect by blocking the airflow from slipping off. This means that lift is created along the full length of the wing.
Which plane would be bigger An Airbus A300 or A Boeing 757?
Well, an A300 is very Wide. The A300 is a Wide aircraft with tiny winglets. The 757 either has no winglets or huge winglets. So the A300 would be bigger. A300 owns airliners like American Airlines or Delta or even the Fedex airplane. A 757 and 767 and 777 all mix together. The 757 owns like Continental or Delta and the U.P.S. The 767 uses like United Or AirTran. The 777 goes about 650-700 m.p.h. They use American, Delta, Almost every airline you can think of.
Who works on an aircraft?
Many specialist technicians work on modern aircraft.
Why are the tips of the wing turned up on an airplane?
They are called winglets, the main function of the winglets is to reduce drag. Reducing drag increases speed and decreases fuel consumption, thereby extending range and saving money.
