The present invention relates to a wing connection device for connecting an outer wing to a center wing, and comprising: a trident joint comprising a first joint fixed to a center wing rear spar of the center wing, a second joint fixed to an outer wing rear spar of the outer wing, and a third joint fixed to a center wing rear spar of the center wing, the third joint is fixed to a butt-joint rib web of the outer wing; and a rear support plate fixed to the rear beam frame of the central wing. In this way, by securing the rear support plate to the rear spar frame of the central wing, it is possible to disperse the load from the outer wing, such that the stress level is reduced, the structural efficiency is improved, and the deformation of the connection structure is reduced. For example, the back stay plate disperses the upward load and disperses the load to the fuselage frame and transfers the load to the fuselage by means of the fuselage frame. The invention also relates to an aircraft comprising such a wing connection device and to a wing connection method.

    本发明涉及一种机翼连接装置,该机翼连接装置用于将外翼连接到中央翼,并且包括:三叉接头,三叉接头包括第一接头、第二接头和第三接头,其中,第一接头固定到中央翼的中央翼后梁,第二接头固定到外翼的外翼后梁,而第三接头固定到外翼的对接肋腹板;以及后撑板,后撑板固定到中央翼的后梁框。这样,通过将后撑板固定到中央翼的后梁框,能够分散来自外翼的载荷,使得应力水平下降,结构效率得到了提高,并且减小了连接结构的变形。例如,后撑板分散了向上的载荷,并且将载荷分散到机身框,并借助机身框传递到机身。本发明还涉及包括这种机翼连接装置的飞行器,并且涉及一种机翼连接方法。
