A collapsible propeller assembly (1) for an aircraft. A collapsible propeller assembly (1) comprises propeller blades (2) pivotally arranged about a pivot axis (P) and a first hub element (3) fixedly arranged relative to the pivot axis (P). The propeller blade (2) or the first hub element (3) comprises at least two openings (13) arranged about the pivot axis (P), each opening (13) being configured to interlock with a raised portion (12) arranged on the other of the propeller blade (2) and the first hub element (3). The at least two openings (13) extend further about the pivot axis (P) than the raised portion (12) such that the propeller blades (2) have a limited play about the pivot axis (P) when the openings (13) are interlocked with the raised portion (12). The biasing element (14) is arranged about the pivot axis (P) and is configured to bias the propeller blades (2) and the first hub element (3) towards each other in an axial direction along the pivot axis (P).

    一种用于飞行器的可折叠螺旋桨组件(1)。可折叠螺旋桨组件(1)包括以可枢转的方式绕枢转轴线(P)布置的螺旋桨叶片(2)和相对于枢转轴线(P)固定布置的第一毂元件(3)。螺旋桨叶片(2)或第一毂元件(3)包括绕枢转轴线(P)设置的至少两个开口(13),每个开口(13)构造成与设置在螺旋桨叶片(2)和第一毂元件(3)中的另一者上的凸起部分(12)互锁。至少两个开口(13)比凸起部分(12)绕枢转轴线(P)延伸得更远,使得在开口(13)与凸起部分(12)互锁时螺旋桨叶片(2)绕枢转轴线(P)具有有限的游隙。偏置元件(14)绕枢转轴线(P)布置并且构造成偏置使螺旋桨叶片(2)和第一毂元件(3)在沿着枢转轴线(P)的轴向方向上朝向彼此偏置。
