The invention belongs to the technical field of airplanes, and particularly relates to a refueling pod hanger suspension structure which comprises a hanger, a pod, a hanger front connector assembly and a hanger rear connector assembly. The upper end of the hanger is fixed on the lower surface of the wing through a hanger front joint assembly and a hanger rear joint assembly; the hanger front connector assembly is provided with three butt joint intersection points, and each butt joint intersection point comprises a positioning point located in the symmetry plane of the hanger in the course direction, and a first main connecting point and a second main connecting point located on the two sides of the positioning point. The hanger rear connector assembly is provided with an auxiliary connecting point located in the symmetry plane of the hanger along the course, the positioning point, the first main connecting point and the second main connecting point are located on the same straight line, a preset included angle is formed between the straight line and the course, and the two inclined rigid connecting points are matched to further bear spanwise and course loads. And the load requirement on the hanger rear joint assembly is reduced, so that the hanger rear joint assembly can adopt single-lug and double-lug hinging, and enough allowance is provided for the heading thermal deformation of the hanger.
本申请属于飞机技术领域,特别涉及一种加油吊舱挂架悬挂结构,包括:挂架、吊舱,挂架前接头组件以及挂架后接头组件;挂架上端通过挂架前接头组件以及挂架后接头组件固定在机翼的下表面;挂架前接头组件具有三个对接交点,分别包括:位于挂架沿航向对称面内的定位点,位于定位点两侧的第一主连接点与第二主连接点;挂架后接头组件具有一个位于挂架沿航向对称面内的辅助连接点,其中,定位点、第一主连接点与第二主连接点在同一直线上,所述直线与航向具有预设夹角,两个斜向的刚性连接点的配合能够进一步承接展向以及航向载荷,减小对于挂架后接头组件的载荷要求,进而挂架后接头组件可以采用单耳双耳铰接,为挂架航向热形变提供足够的余量。
