    Abstract: 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).

    Abstract: A battery connector (7) for connecting a replaceable battery (6) to an aerial vehicle (1), comprising a housing (10) configured for fixing to one of the replaceable battery (6) and the aerial vehicle (1) and a connector element (14) comprising a first connection portion (15) configured for releasable connection to an external connection element (4) of the other one of the replaceable battery (6) and the aerial vehicle (1). The connector element (14) further comprising a second connection portion (18) configured for fixed connection to the replaceable battery (6) or the aerial vehicle (1) to which the housing (10) is configured to be fixed. The connector element (14) is supported in a horizontal direction (XY) in the housing (10) by at least one flexible element (19) positioned at least partly between the connector element (14) and the housing (10), such that there is space between the connector element (14) and the housing (10) in the horizontal direction (XY). The connector element (14) is supported in a vertical direction (Z) in the housing (10) by an upper flexible element (21) positioned between an upper part (23) of the connector element (14) and the housing (10) and a lower flexible element (22) positioned between a lower part (24) of the connector element (14) and the housing (10), such that there is space between the connector element 14 and the housing (10) in the vertical direction (Z).

    Abstract: An unmanned aerial vehicle, having a main body comprising at least an elongate backbone (140) with a forward end piece (130) and a rearward end piece (150). The end pieces are wider than the backbone and comprise coupling facilities for respective rotor arms (200), each said rotor arm configured for supporting motor and propeller assemblies. The unmanned aerial vehicle further comprises a pair of elongated batteries (500). The end pieces and at least a portion of the backbone form receptacles on both sides of the backbone for releasably receiving respective electric batteries (500), wherein the batteries, backbone and end pieces form an elongate and substantially rectangular body assembly.

    Abstract: A foldable propeller assembly for an aerial vehicle is disclosed herein. The foldable propeller assembly comprises a propeller blade arranged pivotably about a pivot axis and a first hub element arranged stationary relative to the pivot axis. The propeller blade or the first hub element comprises at least two openings provided about the pivot axis, each opening is configured for interlocking with a raised portion provided on the other one of the propeller blade and the first hub element. The at least two openings extend further about the pivot axis than the raised portion such that the propeller blade has limited play about the pivot axis when an opening is interlocking with the raised portion. A biasing element is arranged about the pivot axis and configured for biasing the propeller blade and the first hub element towards each other in an axial direction along the pivot axis.
