The invention provides a lifting lug beam structure for an auxiliary fuel tank of an airplane. The lifting lug beam structure comprises an auxiliary fuel tank shell, a lifting beam and a lifting ring piece. The auxiliary fuel tank shell is made of a composite material; a first installation hole is formed in the side face of the auxiliary fuel tank shell and is in a step shape with the inner portion wide and the outer portion narrow. The hanging beam is made of a metal material, and the hanging beam is clamped at the first mounting hole; the hanging beam is provided with a connecting hole, one end of the hanging ring piece is connected into the connecting hole, and the other end of the hanging ring piece is connected with the lower portion of the fuselage. The auxiliary fuel tank shell is made of the composite material, so that the overall weight is reduced, and the impact resistance is high; the side face of the auxiliary fuel tank shell is connected with the hanging beam through the first mounting hole, one end of the hanging ring piece is fixed to the hanging beam, the other end of the hanging ring piece is fixed to the lower portion of the machine body, and stability of the connecting position between the auxiliary fuel tank and the machine body is guaranteed.

    本发明提供了一种飞机副油箱吊耳梁结构,包括副油箱壳体、吊梁和吊环件;副油箱壳体是采用复合材料制作的;副油箱壳体的侧面设有第一安装孔,第一安装孔为内宽外窄的阶梯型;吊梁是采用金属材料制作的,吊梁卡接第一安装孔处;吊梁设有连接孔,吊环件的一端连接连接孔内,吊环件的另一端用于连接机身的下部位置。本发明的副油箱壳体采用复合材料制作,减轻了整体的重量,抗冲击力强;副油箱壳体的侧面通过第一安装孔连接吊梁,使吊环件的一端固定在吊梁处,吊环件的另一端固定机身的下部,确保副油箱与机身之间连接位置的稳固性。
