The invention discloses a multi-wall type wing winglet and an aircraft, and belongs to the technical field of aircraft structural design, the winglet can be quickly interchanged with an inner box section, and the winglet comprises a leading edge, a main box section, a trailing edge, a wingtip fairing and a butt joint rib assembly; all the components are mechanically connected through fasteners to form a winglet multi-closed-chamber bearing structure; the front edge, the main box section and the rear edge are arranged front and back along the unfolding direction, the wingtip fairing is arranged at the end of the wingtip winglet, and the wingtip winglet is connected with the inner box section in an interchange mode through the butt joint rib assembly, so that rapid interchange can be achieved. According to the technical scheme, a multi-wall type main box section force bearing layout scheme and a butt joint rib type interchange connection scheme are adopted, and the contents of overall arrangement of the schemes, load transfer distribution of a force bearing system, interchange connection design and the like are covered. The structure dimension and load transfer function requirements are met, meanwhile, the advantages of being clear in force transfer path, small in space requirement and high in structure efficiency and interchange efficiency are achieved, and application feasibility is achieved.

    本发明公开了一种多樯式机翼翼梢小翼及飞机,属于飞机结构设计技术领域,翼梢小翼能够与内盒段进行快速互换,翼梢小翼包括:前缘、主盒段、后缘、翼尖整流罩、对接肋组件;各部件之间通过紧固件实现机械连接,形成翼梢小翼多闭室承载结构;前缘、主盒段、后缘沿展向前后布置,翼尖整流罩布置在翼梢小翼端部,翼梢小翼通过对接肋组件与内盒段互换连接,从而能够快速互换。本发明技术方案采用多樯式主盒段承力布局方案及对接肋式互换连接方案,涵盖了方案的总体布置,受力系统的传载分配,互换连接设计等内容。在满足结构维形及传载功能需求的同时,具有传力路径清晰,空间需求小,结构效率与互换效率较高的优势,具备应用可行性。
