A foldable propeller assembly (1) for an aerial vehicle. The foldable propeller assembly (1) comprises a propeller blade (2) arranged pivotably about a pivot axis (P) and a first hub element (3) arranged stationary relative to the pivot axis (P). The propeller blade (2) or the first hub element (3) comprises at least two openings (13) provided about the pivot axis (P), each opening (13) is configured for interlocking with a raised portion (12) provided on the other one 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 blade (2) has limited play about the pivot axis (P) when an opening (13) is interlocking with the raised portion (12). A biasing element (14) is arranged about the pivot axis (P) and configured for biasing the propeller blade (2) and the first hub element (3) towards each other in an axial direction along the pivot axis (P).
