The invention relates to a connecting structure of an outer wing (200) and a central wing (300) of an aircraft. The connecting structure comprises a web (10); a rib upper edge strip (11) located above the web (10); a rib lower edge strip (12) located below the web (10); a front Y-joint (13) located on a first side of the web (10); and a rear Y-joint (14) on a second side of the web (10) opposite the first side. The front trifurcate joint (13) and the rear trifurcate joint (14) are provided with lower turnups but not upper turnups. The aircraft outer wing (200) and the central wing (300) are connected together by replacing the upturned edge with a first corner box (120) lapped with the aircraft outer wing (200) and a second corner box (130) lapped with the central wing (300). The invention further relates to a trifurcate connector for the connecting structure and a connecting method of the trifurcate connector, and the problem of low assembly efficiency can be obviously improved while the advantage of high efficiency of a lap joint type connecting structure is reserved.

    本发明涉及一种飞行器外翼(200)与中央翼(300)的连接结构,包括:腹板(10);位于腹板(10)上方的肋上缘条(11);位于腹板(10)下方的肋下缘条(12);位于腹板(10)的第一侧的前三叉接头(13);以及位于腹板(10)的与第一侧相对的第二侧的后三叉接头(14)。前三叉接头(13)和后三叉接头(14)形成有下翻边但没有形成上翻边。通过采用与飞行器外翼(200)搭接的第一角盒(120)和与中央翼(300)搭接的第二角盒(130)来替代上翻边,以将飞行器外翼(200)和中央翼(300)连接在一起。本发明还涉及用于连接结构的三叉接头及其连接方法,在保留搭接式连接结构效率高的优点的同时,能够明显改善装配效率低的问题。
