A rotor assembly for a rotorcraft. A rotor assembly (100) includes a rotor hub (104) and a rotor blade assembly (112). The rotor hub (104) includes a rotor blade support (108). Each rotor blade assembly is coupled to a respective one of the rotor blade supports (108) and includes a swing axle (114), a hub connector (116), a rotor blade (120), and a twisted strip (122). A swing axle (114) extends through a respective one of the rotor blade supports (108) and has a central swing axle axis (110). The hub connector (116) is pivotable about a central swing axle axis (110) relative to the rotor blade support and defines a central hub connector axis (118). The rotor blades (120) are coupled to and pivotable relative to the hub connector (116), and are pivotable with the hub connector (116) relative to a respective one of the rotor blade supports (108) about a central pivot axle axis (110). The twist strip (122) has a first end (124) coupled to the rotor blade (120) and a second end (126) passing through the swing axle (114).
用于旋翼飞行器的旋翼组件。一种旋翼组件(100)包括旋翼毂(104)和旋翼叶片组件(112)。该旋翼毂(104)包括旋翼叶片支撑件(108)。各个旋翼叶片组件联接到相应一个旋翼叶片支撑件(108)并且包括摆动轮轴(114)、毂连接器(116)、旋翼叶片(120)和扭带(122)。摆动轮轴(114)延伸穿过相应一个旋翼叶片支撑件(108)并且具有中心摆动轮轴轴线(110)。毂连接器(116)可相对于旋翼叶片支撑件绕中心摆动轮轴轴线(110)枢转并且限定中心毂连接器轴线(118)。旋翼叶片(120)联接到毂连接器(116)并且可相对于毂连接器(116)枢转,并且与毂连接器(116)一起可相对于相应一个旋翼叶片支撑件(108)绕中心摆动轮轴轴线(110)枢转。扭带(122)具有联接到旋翼叶片(120)的第一端(124)以及穿过摆动轮轴(114)的第二端(126)。
