The present embodiments relate to a periodic pitch angle adjustment device (200) for a rotor (110) or propeller, a rotor (110) having such a periodic pitch angle adjustment device (200), and a rotorcraft (100) having such a rotor (110). A periodic pitch angle adjustment apparatus (200) may include: a lever (230a, 230b) that rotates a rotor blade (212a, 212b) about an associated pitch adjustment axis (235a, 235b); the invention relates to a rotor blade (112) comprising a bearing (220), a lever (230a, 230b), a connecting rod (240a, 240b) mechanically linking the lever (230a, 230b) with the bearing (220) such that the connecting rod (240a, 240b) is movable relative to the central point (223), the bearing (220) being attached to a central connecting rod (250), the central connecting rod (250) being movable and adapted to adjust a periodic pitch angle of the rotor blade (112) from one pitch angle of one position to another pitch angle of another position (265).
当前的实施方式涉及用于旋翼(110)或螺旋桨的周期性桨距角调节设备(200)、具有这种周期性桨距角调节设备(200)的旋翼(110)以及具有这种旋翼(110)的旋翼飞行器(100)。周期性桨距角调节设备(200)可以包括:使旋翼桨叶(212a、212b)围绕相关联的桨距调节轴线(235a、235b)旋转的杠杆(230a、230b);连杆(240a、240b),该连杆(240a、240b)将杠杆(230a、230b)与轴承(220)机械连结,使得连杆(240a、240b)能相对于中心点(223)移动,轴承(220)附接于中心连杆(250)上,中心连杆(250)是可移动的并适于将旋翼桨叶(112)的周期性桨距角从一个位置的一个桨距角调节到另一个位置(265)的另一个桨距角。
