Wing with improved belt sawtooth backswept wing transonic speed sudden stalling characteristic

2016 
Disclosed is a wing with the improved belt sawtooth backswept wing transonic speed sudden stalling characteristic. The wing comprises an inner side leading edge flap, an outer side leading edge flap, an outer wing, an aileron and an inner wing. The outer side of the inner wing is fixedly connected with the outer wing. The outer side leading edge flap is connected to the front edge of the outer wing. The inner side leading edge flap is connected to the front edge of the inner wing. The aileron is connected to the rear edge of the outer wing. Oblique-cutting type obtuse sawtooth transition is arranged between the inner side leading edge flap and the outer side leading edge flap. The oblique-cutting type obtuse sawtooth transition and the outer side leading edge flap are connected together and achieve synchronous deflection. A slit is arranged between the inner side leading edge flap and the obtuse sawtooth transition. An acute angle is formed by the front edge of the obtuse sawtooth transition and the flow incoming direction in the plane of the wing. The oblique-cutting type obtuse sawtooth transition is formed, thus the eddy coming off the upper wing face through sawteeth can be weakened or eliminated, the eddy intensity near the sawteeth is reduced, flowing of the upper wing face is more stable, the adverse pressure gradient of a boundary layer is more moderate, a separation point is further back, and the sudden stalling characteristic of the wing is improved.
