The invention belongs to the field of aircraft structure design, and particularly relates to an aircraft main starting fairing structure which comprises a metal framework, and the metal framework comprises a bulkhead forming a transverse support, a longitudinal beam forming a longitudinal support and a plurality of short beams which form a peripheral frame and are connected end to end; the bulkheads are connected with the longitudinal beams; one side edge of the short beam is connected with the composite skin, and the other side edge is connected with the middle fuselage lower wall plate; the composite material skin is connected with the metal framework through supporting plate nuts and bolts, and the composite material skin is divided into a plurality of modules with different sizes according to areas defined by the bulkheads and the longitudinal beams; one ends of the pull rods are hinged to the metal framework, and the other ends are hung on the lower wall plate of the middle fuselage; flexible connection is mainly adopted, so that the fairing is reasonable in structural distribution, and assembly stress and working fatigue damage are reduced.
本申请属于飞机结构设计领域,特别涉及一种飞机主起整流罩结构,金属骨架,金属骨架包括形成横向支撑的隔框、形成纵向支撑的纵梁以及形成周圈边框的多个首位相连的短梁;隔框与纵梁之间相互连接;短梁的一侧边连接复材蒙皮,另一侧边与中机身下壁板连接;复材蒙皮,复材蒙皮通过托板螺母加螺栓与金属骨架连接,复材蒙皮根据隔框与纵梁围成的区域分为多个大小不同的模块;拉杆,多个拉杆一端铰接金属骨架,另一端吊接中机身的下壁板;本申请主要采用柔性连接,使整流罩结构分布合理,减少装配应力以及工作疲劳损伤。
