The invention belongs to the technical field of design of sweepback wing structures, and particularly relates to a self-adaptive variable sweepback wing structure which comprises a sweepback wing with the root hinged to a machine body; the elastic pieces are connected between the sweepback wings and the aircraft body, and pull the sweepback wings forwards by virtue of elastic force, so that the sweepback wings are kept at a relatively small angle in an initial state; along with the increase of the resistance of the sweepback wings, the sweepback wings can overcome the elastic force of the elastic pieces and deflect backwards, and the angle is increased in a self-adaptive mode; and along with the reduction of the resistance of the sweepback wings, the sweepback wings deflect forwards under the action of the elastic force of the elastic pieces, and the angle is reduced in a self-adaptive manner until the sweepback wings recover to the initial state.
本申请属于后掠机翼结构设计技术领域,具体涉及一种自适应变后掠机翼结构,包括:后掠机翼,根部铰接在机体上;弹性件,连接在后掠机翼、机体之间,依靠弹性力,前向拉动后掠机翼,使后掠机翼在初始状态下保持较小的角度;随着后掠机翼的阻力增加,后掠机翼能够克服弹性件的弹性力,后向偏转,自适应的增大角度;随着后掠机翼的阻力减小,后掠机翼在弹性件的弹性力作用下,前向偏转,自适应的减小角度,直至恢复到初始状态。
