通过风洞试验对双三角翼的内涡襟翼及外涡襟翼进行了研究。探讨了影响涡襟翼效率的各种因素及其规律,其中包括机翼前缘区状态、涡襟翼形状、涡襟翼偏度、内、外涡襟翼的搭配以及后缘襟翼效率等。尤其是根据内外翼涡场的不同研究了复合平面形状机翼内涡襟翼与外涡襟翼设计上的特点,为设计双三角翼的涡襟翼提供了参考数据。研究结果表明,正确设计前缘涡襟翼与后缘襟翼可以优化大后掠双三角机翼的低速性能。
Wind turbine tests were conducted on the inner and outer vortex flaps of the double delta wing. The factors influencing the efficiency of the vortex flaps are discussed, including the state of the leading edge of the wing, the shape of the vortex flaps, the deflection of the flaps, the collocation of the inner and outer vortex flaps and the efficiency of the trailing edge flaps . In particular, the design characteristics of the vortex flaps and the outer vortex flaps in the composite planar wing are studied based on the difference of the vortex field between the inner and outer vanes, which provides reference data for designing the vortex flaps of the double delta wing. The results show that the correct design of leading vortex flaps and trailing edge flaps can optimize the low speed performance of the large swept double delta wing.
