    Abstract: An aircraft includes a main wing (where the main wing is a fixed wing) and a main wing rotor that extends outward on a trailing edge side of the main wing. The aircraft also includes a truncated fuselage, a canard and a canard rotor that is attached to the canard. The aircraft flies at least some of the time using aerodynamic lift acting on the main wing and flies at least some of the time by airflow produced by the main wing rotor. The aircraft is able to fly in those manners because the main wing rotor and the canard rotor are both fixed rotors, each with an axis of rotation that is tilted downward from horizontal at an angle between 20° to 40°, inclusive.

    Abstract: An aircraft includes a canard having a trailing edge, a forward swept and fixed wing having a horizontal plane and a trailing edge, and a plurality of tilt rotors. At least one of the plurality of tilt rotors is attached to the trailing edge of the canard and at least one of the plurality of tilt rotors is attached to the trailing edge of the forward swept and fixed wing. The aircraft also includes a T-tail having a horizontal plane, where the horizontal plane of the T-tail is at a height that is higher than the horizontal plane of the forward swept and fixed wing.

    Abstract: A plurality of port-side tilt rotors and a plurality of starboard-side tilt rotors are configured to rotate between a first rotor position and a second rotor position. The port-side tilt rotors are coupled to a trailing edge of the fixed and forward-swept wing on the port side and the starboard-side tilt rotors are coupled to the trailing edge of the fixed and forward-swept wing on the starboard side. The aircraft also includes a fuselage. When the port-side and starboard-side tilt rotors are in the first rotor position, at least some of a lift to keep the aircraft airborne comes from thrust output by the rotors at least some of the time. When in the second rotor position, at least some of the lift to keep the aircraft airborne comes from aerodynamic lift on the fixed and forward-swept wing at least some of the time.

    Abstract: A first power source includes a high discharge rate battery and a second power source includes a high energy battery. An electronically activated switch switches between the first power source and the second power source in response to a control signal from a power controller. If the electronically activated switch fails, it fails with one of the first power source and the second power source in an open circuit position and with the other one of the first power source and the second power source in a closed circuit position. The power controller generates the control signal, including by: during a vertical landing associated with a vertical takeoff and landing (VTOL) vehicle, generating the control signal to switch from the high energy battery to the high discharge rate battery independent of a measured current.
