The invention relates to a fairing structure of a medium-sized unmanned aerial vehicle with a high lift-drag ratio. The fairing structure is arranged at the wing root of the wing, is connected with the wing root of the wing and the fuselage, and adopts small-angle chamfer rectification; the included angle between the fuselage and the wings is larger than 90 degrees. The fairing structure provided by the invention is positioned at the joint of the wing and the fuselage, and the streamline shape of the fairing structure seals the joint of the wing and the fuselage, so that the fairing structure has dual functions of butting the wing body and reducing air resistance. Several different fairing forms are designed through curved surface creation, aerodynamic analysis and wind tunnel verification are carried out through numerical simulation calculation, and then the fairing shape with good manufacturability and rectification effect is selected.

    本发明涉及一种高升阻比中型无人机的整流罩结构。所述整流罩结构设置在机翼的翼根处,连接所述机翼翼根和机身,采用小角度的倒角整流;所述机身和机翼间的夹角大于90°。本发明提供的整流罩结构位于机翼和机身的结合部,其流线型的外形将机翼和机身相交处封闭起来,起到对接翼身和减小空气阻力的双重作用。本发明通过曲面创成设计了几种不同的整流罩形式,并通过数值仿真计算进行气动分析和风洞验证后选取了工艺性和整流效果较好的整流罩外形。
