The disclosed invention describes a tail rotor head of a rotorcraft, comprising at least a pitch control unit and a tail rotor hub (8), in which a plurality of tail rotor blade holders (6) can be connected at the tail rotor head (3) through openings in the tail rotor hub (8) and the pitch control unit, a tail rotor blade holder (6), such as a tail rotor blade (2), is removably connected to a first side of the tail rotor blade holder (6) and a torsion strip is removably mounted to a second side of the tail rotor blade holder (6), the torsion strip extending radially outward in the direction of the tail rotor blade (2) at least partially through the tail rotor blade holder (6) starting from the tail rotor head (3), this allows for easy replacement of a single rotor blade and simpler maintenance of the tail rotor head. This is achieved by means of a blade holder (6) comprising a belt holding part (60) and a molded blade holding part (61), in which the tension-torsion belt is fastened in the tubular belt holding part (60) by a belt holding bolt (601) in a connecting bore (600) by means of a connecting eye, and the molded blade holding part (61) is fastened in the tubular belt holding part (60) by means of the belt holding bolt (601). One end of the tail rotor blade (2) is detachably and independently fastened and is spaced apart from the torsion strip in a bracket interior (6111) of the mounting bracket (611), and at least one blade bolt (7) passes through a hole (612) in the blade holder (61).

    所公开的发明描述一种旋翼式飞行器的尾旋翼头,尾旋翼头至少包括桨距控制单元和尾旋翼毂(8),其中多个尾旋翼叶片保持器(6)可在尾旋翼头(3)处穿通尾旋翼毂(8)和桨距控制单元中的开口连接,诸如尾旋翼叶片(2)可拆卸地连接在尾旋翼叶片保持器(6)的第一侧处并且拉扭带可拆卸地安装在尾旋翼叶片保持器(6)的第二侧处,其中拉扭带从尾旋翼头(3)开始至少部分地穿过尾旋翼叶片保持器(6)沿尾旋翼叶片(2)的方向径向向外延伸,从而允许容易地更换单个旋翼叶片和更简单地维护尾旋翼头。这通过叶片保持器(6)来达成,所述叶片保持器包括带保持部(60)和模制叶片保持部(61),其中拉扭带在连接孔(600)中利用一个连接孔眼由带保持螺栓(601)紧固在管状带保持部(60)中,而尾旋翼叶片(2)的一个端部可拆卸地独立地紧固并且在安装托架(611)的托架内部(6111)中与拉扭带间隔开,并且至少一个叶片螺栓(7)经过叶片保持部(61)中的孔(612)。
