The invention belongs to the field of aircraft engine mounting structures, and particularly relates to a truss type engine mounting structure. Comprising a U-shaped front frame which is provided with an interface for installing an engine; the middle frame is in a U shape, the front side of the middle frame is connected with the front frame through a plurality of pull rods, and the middle frame is provided with a connector used for installing an engine; the rear frame is annular, the front side of the rear frame is connected with the rear side of the middle frame through a plurality of pull rods, and the rear side of the rear frame is connected with a wing through a plurality of pull rods; wherein every two adjacent pull rods are arranged in a V shape, and a rectangular opening used for disassembling and assembling an engine is formed in the bottom of the engine mounting structure. The turbo-propeller engine can be installed below the wing, the pulling force, the torque and the inertia load of the engine can be borne, force transmission is direct, and the structural weight is light.

    本申请属于飞机发动机安装结构领域,特别涉及一种桁架式发动机安装结构。包括:前框,呈U形,所述前框上设置有用于发动机安装的接口;中框,呈U形,所述中框的前侧通过多根拉杆与所述前框连接,所述中框上设置有用于发动机安装的接口;后框,呈环形,所述后框的前侧通过多根拉杆与所述中框的后侧连接,所述后框的后侧通过多根拉杆与机翼连接;其中,相邻两个拉杆呈V形布置,所述发动机安装结构的底部形成用于发动机拆装的矩形开口。本申请能够将涡轮螺旋桨发动机安装在机翼下方,并且能够承受发动机拉力、扭矩及惯性载荷,传力直接,结构重量轻。
