The invention discloses a rotor wing with variable negative torsion and a rotor wing negative torsion adjusting device, and relates to the technical field of aircraft rotor wing design, the rotor wing negative torsion adjusting device comprises a first rigid section, a torsion section and a second rigid section which are sequentially connected in the spanwise direction of the rotor wing, in the hovering state, the negative torsion of the first rigid section is linearly changed, the first rigid section is in transition connection with the second rigid section through the torsion section, and the second rigid section is in transition connection with the torsion section. The torsion section can be twisted around the spanwise direction of the rotor wing; meanwhile, the rotor wing negative torque adjusting device further comprises a negative torque adjusting mechanism which can apply torsional force to the rotor wing and adjust the negative torque of the rotor wing; the rotor wing is arranged to be of a segmented structure, the torsion sections are arranged between the adjacent rigid sections, the negative torsion of the rotor wing can be changed according to the flight state of the helicopter, and the flight performance of the rotor wing can be improved; and moreover, the negative torque of the rotor wing is adjusted through the negative torque adjusting mechanism, the structure is simpler, and the cost is lower.

    本发明公开一种负扭可变的旋翼和旋翼负扭调节装置,涉及飞行器旋翼设计技术领域,包括沿其展向依次连接的第一刚性段、扭转段和第二刚性段,在悬停状态时,所述第一刚性段的负扭线性变化,并与所述第二刚性段通过扭转段过渡连接,所述扭转段能够绕所述旋翼的展向进行扭转;同时旋翼负扭调节装置还包括负扭调节机构,能够对旋翼施加扭转力,调节旋翼负扭;本发明通过将旋翼设置为分段结构,并在相邻刚性段之间设置扭转段,可以根据直升机的飞行状态改变其负扭,有利于旋翼飞行性能的提升;并且本发明通过负扭调节机构对旋翼负扭进行调节,结构更简单,成本更低。
