The invention discloses an airplane hanging structure. The airplane hanging structure comprises an airplane body, a truss and a fairing, wherein the truss is connected to the airplane body through a pull rod and a butt joint, the fairing is located on the periphery of the truss, the truss is of a variable cross-section integral structure which is symmetric about a central axis, and a rigid frame is arranged in the center of the truss; the front beam and the rear beam of the rigid frame extend towards the left side and the right side respectively to form a plurality of reinforcing beams with variable cross sections, ends of the reinforcing beams on the two sides deform into mounting connectors respectively, and the mounting connectors on the two sides are connected into a whole through longitudinal ribs respectively. The variable cross-section truss structure not only ensures the minimum impact of the suspension structure on the aircraft vibration, the hanging structure is guaranteed to be, sufficient in strength and rigidity, lightest in weight and capable of meeting the hanging requirement of hanging objects, connection between the hanging structure and an airplane body is safe and reliable, installation and disassembly are easy and fast, and the hanging structure does not affect the lift force, resistance and vibration of an airplane.
一种飞机吊挂结构,含有飞机机体、桁架和整流罩,桁架通过拉杆和对接接头连接在飞机机体上,整流罩位于桁架外围,所述的桁架是一个以中心轴对称的变截面整体结构,在桁架的中心是一个刚性框,刚性框的前后梁分别向左右两侧延伸形成多个变截面的加强梁,两侧加强梁的端头分别变形为一个挂载接头,两侧挂载接头分别被一个纵向筋连为整体,变截面桁架结构既保证了吊挂结构对飞机振动影响最小,又确保了吊挂结构的强度刚度足够、重量最轻,能满足挂载物挂载的要求,吊挂结构与飞机机体的连接安全可靠,安装拆卸简单快捷,本申请的吊挂结构不会对飞机的升力、阻力和振动构成影响。
