Patent 10144503 was granted and assigned to Kitty Hawk on December, 2018 by the United States Patent and Trademark Office.
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.
