The invention belongs to the technical field of aircraft structure design, and discloses an aircraft spar butt joint structure which comprises an upper butt joint piece, a lower butt joint piece, an inner connecting piece and an outer connecting piece, one side of the upper butt joint piece is connected to an inner upper edge strip of an inner section spar and an outer upper edge strip of an outer section spar, and the other side of the upper butt joint piece is connected to a lower butt joint piece. One side of the upper butt joint piece is connected to an inner-section web of the inner-section spar, the other side of the upper butt joint piece is connected to an outer-section web of the outer-section spar, one side of the lower butt joint piece is connected to an inner lower edge strip of the inner-section spar and an outer lower edge strip of the outer-section spar, the other side of the lower butt joint piece is connected to the inner-section web and the outer-section web, the inner connecting piece is arranged on the inner-section web and the outer-section web, and one end of the inner connecting piece is connected to the upper butt joint piece. The outer connecting piece is installed on the side, away from the inner connecting piece, of the inner section spar and the side, away from the inner connecting piece, of the outer section spar and connected to the inner section web and the outer section web. Through the arrangement, the airplane spar butt joint structure can improve the sealing performance and the structural efficiency, reduce the assembly difficulty and avoid composite material failure under the condition that the structural strength is guaranteed.

    本发明属于飞机结构设计技术领域,公开了一种飞机翼梁对接结构,其包括上对接件、下对接件、内连接件和外连接件,上对接件一侧连接于内段翼梁的内上缘条和外段翼梁的外上缘条,另一侧连接于内段翼梁的内段腹板和外段翼梁的外段腹板,下对接件一侧连接于内段翼梁的内下缘条和外段翼梁的外下缘条,另一侧连接于内段腹板和外段腹板,内连接件设置于内段腹板和外段腹板上,一端连接于上对接件,另一端连接于下对接件,外连接件安装于内段翼梁和外段翼梁背离内连接件的一侧,并连接于内段腹板和外段腹板。通过上述设置,本申请的飞机翼梁对接结构能够在保证结构强度的情况下,提高密封性和结构效率,降低装配难度,避免复材失效。
