Abstract: A system which includes a plurality of cylindrical battery cells that have a uniform orientation, where each of the plurality of cylindrical battery cells has a first planar surface and a second planar surface. There is also a thermal management and structural (TMS) plate that is disposed at the second planar surface of the plurality of cylindrical battery cells and a bonding plate that is disposed at the first planar surface of the plurality of cylindrical battery cells. At least some electrical connections between the plurality of cylindrical battery cells and the bonding plate include ribbon bonding.

Abstract: 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.
