    Abstract: A propeller assembly (200) comprising a propeller hub (201) which can be driven about an axis and at least two propeller blades (203) each mounted to the hub at a point distal from the axis by pivoting means (203, 211, 212) alloying the propeller blades to pivot generally parallel to the said axis between at least two positions relative to the hub, a first, folded position in which the propeller blade is not aligned with the axis and the point and a second, deployed position in which the propeller blade is aligned with the axis and the point, in which the pivoting means (203, 211, 212) is configured to allow the propeller blades to pivot freely relative to the hub when in the first position and, on driving the hub about the axis, to allow the propeller blades to pivot relative to the hub until the or each propeller blade is aligned with the axis and the point, the pivoting means being adapted to hold the or each propeller blade in the second position for as long as the bub is driven. An air vehicle (700) comprising at least one such propeller assembly (701) is also described..

    Abstract: Multiple motors may drive (rotate) a single shaft coupled to a propeller. The motors may be selected such that a first motor is capable of rotating the drive shaft in an event of a failure of a second motor coupled to the drive shaft. A one-way clutch bearing, or similar device, may interface between a motor and the drive shaft to enable free rotation of the drive shaft in an event of the motor becoming inoperable, such as the motor freezing or locking in a position due to failure caused by overheating or caused by other conditions or events. Use of the second motor may secure a position of the drive shaft which may support the propeller in radial eccentric loading.

    Abstract: A propeller alignment device (102) is described. The propeller alignment device (102) can include a second retainer attached to a propeller (112) and a motor (104). The propeller alignment device (102) can also include a first retainer (114) that does not rotate, but that is aligned with the second retainer (116). The first retainer (114) can include two or more magnets (120A,120B) oppositely orientated relative to each other. The second retainer (116) can also include two or more magnets (118A,118B) oppositely orientated relative to each other. As the second retainer (116) rotates relative to the first retainer (114), the magnets may altematingly align with each other. In the absence of a current applied to the motor (104), the magnets may magnetically bias the second retainer (116) into a predetermined orientation relative to the first retainer (114). The predetermined orientation can be predetermined to correspond to an alignment of the propeller (112) that is desirable (e.g., that minimizes aerodynamic drag on the propeller).

    Abstract: This disclosure describes a configuration of an unmanned aerial vehicle ("UAV") (100) that will facilitate extended flight duration. The UAV may have any number of lifting motors (102). For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (also known as an octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV also includes a pivot assembly (109) that may rotate about an axis (624) from a lifting position to a thrusting position. The pivot assembly may include two or more offset motors (610) that generate a differential force that will cause the pivot assembly to rotate between the lifting position and the thrusting position without the need for any additional motors or gears.
