Background technique
With the development of aircraft industry, many aircrafts nowadays have been developed, Whitcomb doctor grinds in the 1970s
After issuing a kind of winglet, winglet begins to largely apply on the army and the people's transporter, because wing generates lift in flight
Meanwhile the higher-pressure region air-flow of lower aerofoil can flow to top airfoil around wingtip, form strong swirling air stream, and edge after slave flapwise
Very long a distance is stretched, they have taken away energy, increase air drag.Winglet is exactly for slackening this resistance.
According to statistics a frame Boeing 737 airplane install additional winglet after will save 300 tons of fuel oils every year, this be only airline saved at
This, increases profit, while also to alleviate world's fuel oil increasingly rare situation.
There is the form of many winglets at present, can be summarized as two classes：
Upper single entry winglet layout：Advantage is that usually have certain camber angle, it is possible to provide additional lift.The disadvantage is that the wing
Root generates additional moment of flexure, has an adverse effect to structure.
Vertical type winglet layout：It is generally orthogonal to wing, additional moment of flexure will not be generated, but will not provide additional
Lift.
Some researches show that aircrafts in different state of flight flight, and the shape, size of winglet can all have not saving fuel oil
Same performance.Such as aircraft effect of winglet and little when taking off, in some instances it may even be possible to have an adverse effect, so in certain short-terms
Not filling winglet when flight may be better choice.Such as aircraft range requires in high-altitude and at low latitude, to the shape of winglet
Also there is different requirements.
