The invention provides a propeller and a tilt rotorcraft, the propeller comprises a central column and at least one blade, a wing root of the blade is arranged on the central column, and the blade is made of a flexible and deformation-recoverable material; when the propeller is in a first working mode, the difference value between the blade angle at the blade root and the blade angle at the blade tip is a first torsion angle, and the first working mode is a take-off and landing mode or a hovering mode; when the propeller is in a second working mode, the difference value between the blade angle at the blade root and the blade angle at the blade tip is a second torsion angle, the second torsion angle is larger than the first torsion angle, and the second working mode is a cruising mode; the propeller further comprises a driving device for driving the blades to be converted between the first torsion angle and the second torsion angle, the driving device is arranged on the central column, and the blades are in transmission connection with the driving device.

    本发明提供了一种螺旋桨及倾转旋翼机,所述螺旋桨包括中心柱以及至少一个桨叶,所述桨叶的翼根设在所述中心柱上,所述桨叶由柔性且可形变恢复的材料制成;当所述螺旋桨处在第一工作模式,所述桨叶翼根处的桨叶角与所述桨叶翼尖处的桨叶角之间的差值为第一扭转角,所述第一工作模式为起降模式或悬停模式;当所述螺旋桨处在第二工作模式,所述桨叶翼根处的桨叶角与所述桨叶翼尖处的桨叶角之间的差值为第二扭转角,所述第二扭转角大于所述第一扭转角,所述第二工作模式为巡航模式;所述螺旋桨还包括驱动所述桨叶在所述第一扭转角与所述第二扭转角之间相互转换的驱动装置,所述驱动装置设在所述中心柱,所述桨叶与所述驱动装置传动连接。
