The invention provides a wingtip deflectable wing with a self-locking function, and relates to the technical field of aircrafts, the wingtip deflectable wing comprises a wing section, a self-locking mechanism and a wingtip, the wingtip is rotatably connected to the tail end of the wing section, and the self-locking mechanism can lock and unlock the wingtip in an extended state. The self-locking mechanism is used for locking and unlocking the wingtip, so that when gust exists, the wingtip can be unlocked to realize free deflection of the wingtip, the problem that additional load generated when the aircraft encounters the gust in the flight process is slowed down is solved, when the gust does not exist, the wingtip can be locked, and the wingtip can be prevented from being damaged. The problem that the aeroelastic stability of the whole structure of the wing is reduced due to free oscillation of the wingtip is solved.

    本发明提供一种带有自锁功能的翼尖可偏摆机翼,涉及飞行器技术领域,包括:机翼段、自锁机构和翼尖,所述翼尖能够转动的连接于所述机翼段的末端,所述自锁机构能够对处于伸展状态下的所述翼尖进行锁定和解锁。本发明采用自锁机构来对翼尖进行锁定和解锁,由此,当存在阵风时,则可对翼尖解锁来实现翼尖的自由偏摆,进而解决飞机在飞行过程中由于遭遇阵风时产生的附加载荷减缓问题,当不存在阵风时,则可对翼尖进行锁定,以解决由于翼尖自由振荡引发的机翼整体结构气动弹性稳定性降低的问题。
