The invention belongs to the field of airplane rear fuselage design, and particularly relates to a rear fuselage structure of an airplane. The rear fuselage structure comprises an upper expansion edge, a lower expansion edge, an engine jet pipe and a beaver tail configuration deflection mechanism. The upper expansion edge is arranged on the upper side of the aircraft rear fuselage; the lower expansion edge is arranged on the lower side of the rear fuselage of the aircraft, the length of the lower expansion edge is larger than that of the upper expansion edge, and a mounting space is reserved between the lower expansion edge and the upper expansion edge; the engine jet pipe is arranged in a mounting space reserved between the lower expansion edge and the upper expansion edge, and the engine jet pipe is in butt joint with the upper expansion edge and the lower expansion edge. The beaver tail configuration deflection mechanism is mounted at the tail end of the lower expansion edge through a rotating shaft, and the beaver tail configuration deflection mechanism can deflect up and down around the lower expansion edge. According to the rear fuselage structure of the airplane, the spraying pipe can be shielded, the stealth effect is improved, the beaver tail configuration deflection mechanism is additionally arranged, and the pitching control capacity of the airplane can be enhanced through deflection of the beaver tail configuration deflection mechanism.

    本申请属于飞机后机身设计领域,特别涉及一种飞机后机身结构。包括:上膨胀边,下膨胀边,发动机喷管以及海狸尾构型偏转机构。上膨胀边设置在飞机后机身上侧;下膨胀边设置在飞机后机身下侧,下膨胀边的长度大于上膨胀边,且下膨胀边与上膨胀边之间预留有安装空间;发动机喷管设置在下膨胀边与上膨胀边之间预留的安装空间中,且发动机喷管分别与上膨胀边以及下膨胀边对接安装;海狸尾构型偏转机构通过转轴安装在下膨胀边的末端,且海狸尾构型偏转机构能够绕下膨胀边上下偏转。本申请的飞机后机身结构,不仅能够对喷管进行遮挡提高隐身效果,并且增加海狸尾构型偏转机构,通过海狸尾构型偏转机构的偏转能够增强飞机俯仰操纵能力。
