The invention discloses a variable-pitch direct-drive hybrid power composite wing vertical unmanned aerial vehicle. The variable-pitch direct-drive hybrid power composite wing vertical unmanned aerial vehicle comprises a variable-pitch direct-drive hybrid power system and a whole vertical take-off and landing fixed wing unmanned aerial vehicle carrying variable-pitch direct-drive hybrid power. According to the variable-pitch direct-drive hybrid power system, a piston engine direct-drive generator serves as a main power source, and a power lithium battery serves as an auxiliary power source and an electric energy center; the complete machine design comprises complete machine mechanical structure design, weight accounting and iteration and flight working mode design. A vertical take-off and landing fixed-wing unmanned aerial vehicle layout combining a fixed wing with four rotors is adopted; the high-aspect-ratio wings and the large-size rotors used by the aircraft body can provide vertical lift force, and meanwhile, the vertical maneuvering time of the whole aircraft is remarkably prolonged; the variable pitch propeller propelling device directly driven by the front output shaft of the piston engine can provide horizontal pulling force, and meanwhile, the level flight cruising performance of the whole machine is remarkably improved; the reinforced spar and the wing can provide better bending resistance and torsion resistance for the aircraft.
