According to the supporting rod for connecting the wings and the fuselage of the airplane, an upper hinge and a lower hinge which can rotate horizontally are arranged on the side portion of the fuselage, and the upper hinge is hinged to the wings; a front cross beam and a rear cross beam are arranged in the skin of the wing, and the two supporting rods are connected between the two cross beams and the lower hinge respectively and used for improving the connecting strength of the wing and the fuselage. An oil cylinder and a piston are arranged in the supporting rod, the piston is connected with the cross beam through a rod piece, and the oil cylinder is divided into an upper oil cavity and a lower oil cavity by the piston; the two supporting rods comprise the front supporting rod and the rear supporting rod, the upper oil cavity of the front supporting rod is communicated with the lower oil cavity of the rear supporting rod through a pipeline, and the lower oil cavity of the front supporting rod is communicated with the upper oil cavity of the rear supporting rod through a pipeline. The supporting rods are arranged between the fuselage and the wings, so that the bending amount of the wings can be reduced, and the wings are prevented from being broken due to overfatigue; the connecting strength of the wings and the connecting strength of the wings and the fuselage can be improved, the weight of the aircraft is reduced, and backward folding of the wings is achieved.
一种用于连接飞机机翼与机身的撑杆,在机身的侧部设置有能够水平转动的上铰链和下铰链,其中,上铰链与机翼铰接;在机翼的蒙皮内设置有前后两根横梁,所述撑杆为两根,分别连接在两根横梁与下铰链之间,用于提高机翼与机身的连接强度。在撑杆内设置有油缸和活塞,活塞通过杆件与横梁连接,活塞将油缸分为上油腔和下油腔;两根撑杆分别为前撑杆和后撑杆,前撑杆的上油腔通过管道与后撑杆的下油腔连通,前撑杆的下油腔通过管道与后撑杆的上油腔连通。本发明在机身与机翼之间设置撑杆,一是能够降低机翼的弯曲量,避免机翼因过度疲劳而断裂;二是能够提高机翼、以及机翼与机身的连接强度,减轻飞机的重量,实现机翼的向后折叠。
