The invention relates to the technical field of mechanical structures, in particular to a light helicopter fuselage which comprises a shell, a fuselage truss is arranged in the shell, and a fuel tank is mounted in the fuselage truss; engine cabin doors are arranged on the two sides of the shell; a fairing is detachably installed at the bottom of the shell in a clamped mode; and a tail beam is arranged at the rear end of the shell. The fairing comprises a front fairing body and a rear fairing body, and the front fairing body and the rear fairing body are fixed to the bottom of the shell through arranged lock catches. According to the light helicopter fuselage, the fairing is detachably arranged at the bottom of the shell, so that the fairing can be conveniently disassembled to overhaul a fuel tank, an engine and other parts installed in the shell, meanwhile, the overall stability of the shell is improved through the fuselage truss, and external protection can be provided for the fuel tank.

    本发明涉及机械结构技术领域,具体为一种轻型直升机机身,包括壳体,所述壳体内设置有机身桁架,所述机身桁架内安装有燃料箱;所述壳体的两侧设置有发动机舱门;所述壳体的底部卡拆卸的安装有整流罩;所述壳体的后端设置有尾梁。所述整流罩包括前整流罩和后整流罩,且所述前整流罩和后整流罩均通过设置的锁扣固定在所述壳体的底部。该轻型直升机机身,通过将整流罩可拆卸的置于壳体的底部,便于拆开整流罩对壳体内安装的燃料箱、发动机等零部件的检修,同时,机身桁架提高壳体整体的稳定性,且能为燃料箱提供外部防护。
