The invention discloses a novel multi-driving vertical takeoff and landing fixed wing unmanned aerial vehicle, and relates to the technical field of aircrafts. The unmanned aerial vehicle comprises aninner segment wing, wherein two inner segment wing fans are symmetrically arranged at the upper end of the inner segment wing; outer segment wings are respectively arranged on the left side and the right side of the inner segment wing; an outer segment wing ducted fan is arranged on each outer segment wing; a supporting frame is arranged between the inner segment wing and each outer segment wing;an oil supply system and a control system are arranged in the inner segment wing; the control system is used for controlling the oil supply system to provide power for an engine and changing the attitude of the unmanned aerial vehicle through controlling the rotating speed of the engine, the condition of a duct cover plate and the thread pitch of the outer segment wing ducted fans according to acontrol strategy. The novel multi-driving vertical takeoff and landing fixed wing unmanned aerial vehicle can adjust the flight attitude in real time accurately, and the windward area of wings is reduced, so that the unmanned aerial vehicle can adapt to an adverse air current environment, the robustness and stability of the flight of the system are improved, and the process of implementation is promoted.
