Abstract
An electrically or hybrid powered multirotor aircraft with complete redundancy on all of its functions of lift, of propulsion, and of control, the aircraft having optimized energy consumption and comprising: a longitudinal structure having two longitudinal beams; a fuselage fastened to the longitudinal structure; two fixed wings serving essentially to provide the aircraft with lift in cruising flight and arranged at respective ends of the longitudinal structure and in a common first plane; at least six rotors serving essentially to provide the aircraft with lift during stages of takeoff and landing, the rotors being arranged in a common second plane distinct from the first plane and parallel to the first plane in such a manner as not to be situated vertically above or below a fixed wing; and two propulsion propellers. An electrical or hybrid power plant serves to drive the rotors and the propulsion propellers in rotation.
