A connection structure for connecting a center wing back rest and an outer wing back rest of an aircraft, in which the connection structure comprises a trident joint to which the center wing back rest and the outer wing back rest are respectively connected in a force-transmitting manner, a back rest frame is provided at a back rest region, and the connection structure comprises a diagonal plate structure, the inclined supporting plate structure is connected with the rear beam frame in a force transmission mode and used for supporting the rear beam frame, the connecting structure further comprises a central wing inner angle box and a central wing outer angle box, and the central wing inner angle box and the central wing outer angle box are connected to the central wing rear beam in a force transmission mode respectively. And the central wing inner angle box and the central wing outer angle box are oppositely arranged relative to one fork part of the three-fork joint. The diagonal bracing plate structure is connected with the central wing outer corner box in a force transmitting manner, so that the main lift load from the outer wing is shared to the middle fuselage. The connecting structure is high in structural efficiency and good in maintainability, and manufacturability and economical efficiency are improved. The invention further provides an aircraft comprising the connecting structure.
一种用于连接飞机的中央翼后梁和外翼后梁的连接结构,其中,连接结构包括三叉接头,中央翼后梁和外翼后梁分别力传递地连接到该三叉接头的不同叉部,在后梁区处设有后梁框,并且连接结构包括斜撑板结构,斜撑板结构与后粱框力传递地连接,用于支持后粱框,连接结构还包括中央翼内角盒和中央翼外角盒,其中,中央翼内角盒和中央翼外角盒分别力传递地连接到中央翼后梁,并且中央翼内角盒和中央翼外角盒关于三叉接头的一个叉部相对地设置。斜撑板结构与中央翼外角盒力传递地连接,从而分担来自外翼的主要升力载荷到中机身。该连接结构的结构效率高,维修性好,且工艺性和经济性均有所提高。还提出了一种包含该连接结构的飞机。
