  • Publication number: 20220402603
    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.
