WIG CRAFT AND JOINTING DEVICE FOR COUPLING FUSELAGE AND MAIN WING TO EACH OHTER

摘要

The present invention provides a wing-in-ground craft and a jointing device for coupling a fuselage and main wings of a wing-in-ground craft. The wing-in-ground craft comprises: a fuselage having a ring-shaped frame extended in a circumferential direction; a pair of main wings symmetrically arranged in the left and right sides of the fuselage and having spurs positioned corresponding to the frame; and a jointing device for connecting the fuselage and the main wings. The jointing device comprises: a female lug installed in the frame and having a head part protruding outward from the fuselage to connect the fuselage and the main wings; a male lug installed in the spurs and having a front end inserted in the head part of the female lug; and a coupling unit positioned in the outside of the fuselage and coupling the head part of the female lug and the front end of the male lug.
