The invention provides an aircraft equal-straight-part skin assembly and an aircraft equal-straight-part framework, the aircraft equal-straight-part skin assembly comprises a plurality of wall plates which are annularly and sequentially spliced, the inner surfaces of the wall plates are flush, and the inner surfaces of all the wall plates form a smooth cylindrical surface; the outer surface of each wall plate comprises a plurality of equal-thickness areas and transition areas which are alternately arranged in the heading direction, the thickness of any equal-thickness area is not smaller than the corresponding minimum load thickness, the surface of any transition area is an annular face arranged in the annular direction, and the boundaries of the two sides of any transition area make contact with the adjacent equal-thickness areas correspondingly. The thicknesses of the boundaries on the two sides of the transition areas are equal to the thicknesses of the equal-thickness areas in contact with the transition areas, and any transition area has a preset gradient in the course; therefore, under the condition that the aerodynamic performance of the aircraft is guaranteed, the configuration of the stringer and the annular frame tightly attached to the inner surface of the aircraft skin is simplified, and the manufacturing cost of the aircraft is reduced.
本申请提供一种飞行器等直部蒙皮组件及飞行器等直部框架,其中,飞行器等直部蒙皮组件包括多块环向依次拼接且内表面平齐的壁板,所有壁板的内表面形成一个光滑的柱面,各壁板的外表面在航向上均包括多个交替排列的等厚区域和过渡区域,任一等厚区域的厚度均不小于对应的最小载荷厚度,任一过渡区域的表面均为沿环向设置的环面,任一过渡区域两侧边界分别与相邻的等厚区域相接触,且过渡区域两侧边界处的厚度分别与其相接触的等厚区域的厚度相等,任一过渡区域在航向上均具有预设坡度;从而在保证飞行器气动性能的情况下,简化了紧贴飞行器蒙皮内表面的长桁和环向框的构型,有利于减小飞行器的制造成本。
