The invention relates to the technical field of helicopter manufacturing, in particular to an unmanned helicopter fuselage truss structure which comprises an engine truss, a first bulkhead, a speed reducer truss and a second bulkhead. The engine truss comprises a first fixing point, a second fixing point, a third fixing point and a fourth fixing point which are arranged in pairs, and a first mounting point, a second mounting point and an undercarriage mounting point; and the first bulkhead and the second bulkhead are connected through the speed reducer truss. The truss structure improves the mounting stability of the engine and the speed reducer of the helicopter, stabilizes the gravity center of the helicopter fuselage, keeps the structural strength of the fuselage, improves the load capacity of the fuselage, and meets the load flight requirements of the helicopter.
本发明涉及直升机制造技术领域,具体为一种无人直升机机身桁架结构,包括:发动机桁架、第一隔框、减速器桁架和第二隔框;所述发动机桁架包括成对设置的第一固定点、第二固定点、第三固定点、第四固定点,以及第一安装点、第二安装点、起落架安装点;所述第一隔框与所述第二隔框之间通过所述减速器桁架进行连接。该桁架结构,提高直升机发动机和减速器安装的稳定性,且稳定直升机机身的重心,保持机身结构强度,提高机身的负载能力,满足直升机的负载飞行要求。
