According to the aircraft rear fuselage, a skin comprises two upper arc surfaces, two lower arc surfaces and a plurality of lower arc surfaces, two lower arc surfaces; the lower arc surface is a uniform section; the upper plane is connected with the two upper arc surfaces; the lower plane is connected with the two lower arc surfaces; the side planes are respectively connected with the upper arc surface and the lower arc surface; the lower plane, the upper plane and the side plane are all planes, the axes of the two upper arc surfaces are parallel to each other, the axes of the two lower arc surfaces are parallel to each other, and the distance between the axis of each upper arc surface and the axis of the adjacent lower arc surface is gradually reduced from the front of the course to the rear of the course. The device is composed of a single-curvature arc surface and a single-curvature plane, the design, the process and the manufacturing are simple, and the manufacturing cost is reduced; according to the scheme, the combined metal plate frame is adopted and mainly comprises the arc-shaped parts and the straight section bars, the arc-shaped parts at the same positions are of the same structure, the straight section bars are standard section bars, the die cost is greatly reduced, and the production efficiency is improved.

    申请提供了一种飞机后机身,蒙皮包括:两个上圆弧面,上圆弧面为等截面;两个下圆弧面;下圆弧面为等截面;连接两个上圆弧面的上平面;连接两个下圆弧面的下平面;分别连接上圆弧面与下圆弧面的侧平面;下平面、上平面以及侧平面均为平面,两个上圆弧面的轴线相互平行,两个下圆弧面的轴线相互平行,上圆弧面的轴线与其相邻下圆弧面的轴线之间的距离由航向前方到航向后方逐渐减小,本专利方案采用了简单蒙皮,由单曲度的圆弧面和平面组成,设计、工艺和制造比较简单,降低了制造成本;本专利方案采用了组合式钣金框,主要由弧形零件和直形型材组成,相同部位的弧形零件是全同结构,直形型材采用标准型材,极大地降低模具成本,提高生产效率。
