The invention provides a sweepback type three-beam thin wing composite material wing structure which comprises a wing main body and ailerons mounted in wing main body mounting grooves, and the wing main body comprises a wing framework and a wing outer skin structure on the outer side of the wing framework; the wing framework comprises a longitudinal component unit and a transverse component unit, the longitudinal component unit comprises a front beam, a middle beam and a rear beam, acute angles are formed between the front beam and the middle beam, and acute angles are formed between the middle beam and the rear beam; the transverse member unit comprises a plurality of wing ribs which are arranged between the front beam and the middle beam, between the middle beam and the rear beam and on the side, facing the front of the fuselage, of the front beam; the front beam, the middle beam and the rear beam are each provided with a spar connector used for being connected with a fuselage. The wing provided by the invention adopts a three-beam structure, and each wing spar has a mouth-shaped cross section, so that each wing spar forms a multi-wall form and can bear bending moment and torque brought by larger effective load of the wing, and the wing structure is light in weight, high in strength and good in integrity.
本发明创造提供了一种后掠式三梁薄翼复合材料机翼结构,包括机翼主体及机翼主体安装槽内安装的副翼,所述机翼主体包括机翼骨架及机翼骨架外侧的机翼外蒙皮结构;所述机翼骨架包括纵向构件单元和横向构件单元,纵向构件单元包括前梁、中梁和后梁,前梁与中梁之间、以及中梁与后梁之间均呈锐角布置,横向构件单元包括在前梁与中梁之间、在中梁与后梁之间、以及在前梁朝向机身前方的一侧布置的若干翼肋;前梁、中梁和后梁上均设有用于与机身连接的翼梁连接头。本发明创造提供的机翼采用三梁结构,每一翼梁成口形截面,使得各翼梁形成多墙形式,能承担较大的机翼有效载荷所带来的弯矩和扭矩,机翼结构重量轻,强度高,整体性好。
