The invention discloses a rotor variable-elongation mechanism, which relates to the technical field of aircrafts, and comprises a shell, an adjusting device and an expanding device, the shell is used for being fixedly connected with the tip of a fixed rotor wing of the rotor wing blade, a containing cavity is formed in the shell, the end, away from the fixed rotor wing, of the shell is a first end, and the first end is provided with a first opening communicating with the containing cavity; the adjusting device is connected with the shell; the extension device is connected with the adjusting device, and the adjusting device is used for driving at least part of the extension device to extend out of or be accommodated in the accommodating cavity through the first opening in the length direction of the rotor blade. The invention further provides a rotor blade and a tilting rotorcraft. According to the rotor variable-elongation mechanism, the rotor blade and the tilting rotorcraft provided by the invention, the length of the rotor blade can be changed, and the strength of the rotor blade can be ensured.

    本发明公开了一种旋翼变展长机构,涉及飞行器技术领域,包括壳体、调节装置及扩展装置;壳体用于与旋翼桨叶的固定旋翼的尖部固定连接,且壳体内具有容置腔,且壳体用于背离固定旋翼的一端为第一端,第一端具有与容置腔连通的第一开口;调节装置与壳体连接;扩展装置与调节装置连接,调节装置用于驱动扩展装置至少部分在旋翼桨叶的长度方向上通过第一开口伸出于或收纳于容置腔。本发明还提供一种旋翼桨叶及倾转旋翼机。本发明提供的旋翼变展长机构、旋翼桨叶及倾转旋翼机,能够改变旋翼桨叶的长度,并能够保证旋翼桨叶的强度。
