摘要： Battery assembly techniques and a corresponding system are disclosed. In various embodiments, the battery assembly techniques include compressing battery cells and inserting the battery cells in a can. Battery cells are stacked and then compressed using pneumatic cylinders that exert pressure on a first external layer of the stacked battery cells. A first portion of the stacked battery cells is released from the pneumatic cylinders while a second portion of the battery cells remains compressed. The first portion of the stacked battery cells is inserted in a can. In various embodiments, friction decreasing materials are added to the stacked battery cells to compress the stacked battery cells or ease insertion.

摘要： A propeller includes a blade free to rotate. A first stop is positioned to mechanically engage one or both of a first portion of the blade and a first structure coupled to the blade when the blade is in a first position at a first end of the rotational range of motion. A second stop is positioned to mechanically engage one or both of a second portion, of the blade and a second structure coupled to the blade when the bia.de is in a second position at a second end of the defined rotational range. The blade rotates to the first position against the first stop when the propeller is rotated in a first direction and to the second position against the second stop when the propeller is rotated in a second direction.

摘要： A vehicle includes a fuselage, a wing, a pylon that is coupled to the wing, and a tractor tiltrotor. The tractor tiltrotor is coupled to the pylon and is located forward of the wing; the tractor tiltrotor tilts upwards during a hover mode. There is also a pusher tiltrotor where the pusher tiltrotor is coupled to the pylon and is located aft of the wing; the pusher tiltrotor tilts downwards during the hover mode. The tractor tiltrotor and the pusher tiltrotor rotate about a longitudinal and coaxial axis of rotation in a cruise mode.
