The invention belongs to the technical field of airplane middle fuselage frame beam framework structure design, and particularly relates to an airplane middle fuselage frame beam framework structure which comprises two fuselage reinforcing frames which are oppositely arranged, and two fuselage longitudinal beams which are oppositely arranged; each fuselage longitudinal beam and the two fuselage reinforcing frames intersect and are integrally formed, the section of the intersection portion of each fuselage longitudinal beam and the corresponding fuselage reinforcing frame is in a cross shape, no disconnection portion exists on the fuselage longitudinal beams and the fuselage reinforcing frames, the load transmission is continuous, fatigue damage is not likely to happen, a large number of structures and parts do not need to be arranged for auxiliary connection, and the weight is low. And the fuselage longitudinal beams and the fuselage reinforcing frames are integrally formed, previous plane load transfer is changed into three-dimensional load transfer, and the overall rigidity of the structure is improved.

    本申请属于飞机中机身框梁骨架结构设计技术领域,具体涉及一种飞机中机身框梁骨架结构,包括:两个机身加强框,相对设置;两个机身纵向梁,相对设置;每个机身纵向梁与两个机身加强框相交,一体成型,机身纵向梁与机身加强框的相交部位的截面呈十字型,机身纵向梁、机身加强框上不存在断开部位,传载连续,不容易发生疲劳损坏,不需要设置大量的结构、零件辅助连接,重量较轻,且设计机身纵向梁与机身加强框一体成型,由以前的平面传载变为三维传载,结构整体刚度提高。
