The invention provides a wingtip low-resistance hanger structure which comprises a front section, a middle section and a rear section, the front section, the middle section and the rear section are sequentially connected, and the front section and the rear section form a triangle on a pitching section, so that a front edge sweepback angle delta 1 is formed at the front end of the front section, and a rear edge sweepforward angle delta 2 is formed at the tail end of the rear section; the front section is contracted from front to back on the yaw section, and the rear section is contracted from back to front on the yaw section, so that a front edge wedge angle delta 3 is formed at the front end of the front section, a rear edge contraction angle delta 4 is formed at the tail end of the rear section, and finally the low-wind-resistance wingtip hanger in a small chord length space is formed. The wingtip low-resistance pylon structure provided by the invention solves the design contradiction of a pylon in a small chord length space of the wingtip of a wing, and can achieve the purposes of reducing the flight resistance and improving the flight performance.

    本申请提供了一种翼尖低阻挂架结构,包括:前段、中段及后段,所述前段、中段与后段依次连接,其中,前段和后段在俯仰截面上成三角形,从而使前段的前端形成前缘后掠角δ1、后段的尾端形成后缘前掠角δ2;所述前段在偏航截面上自前向后成收缩状,所述后段在偏航截面上自后向前成收缩状,从而使前段的前端形成前缘尖劈角δ3,后段的尾端形成后缘收缩角δ4,最终形成小弦长空间下的低风阻翼尖挂架。本申请提供的翼尖低阻挂架结构解决了机翼翼尖小弦长空间下挂架的设计矛盾,可实现降低飞行阻力、提高飞行性能的目标。
