Suction type electric propulsion unmanned aerial vehicle utilizing solar energy

The invention provides an air-breathing electric propulsion unmanned aerial vehicle utilizing solar energy, which comprises a vehicle body, an annular truss type photoelectric conversion device is carried on the vehicle body, the photoelectric conversion device comprises an annular truss unfolding mechanism and a foldable film type photoelectric conversion array, and the film type photoelectric conversion array is supported and connected by the annular truss unfolding mechanism. Unfolding or folding of the film type photoelectric conversion array is realized through the annular truss unfolding mechanism; a thrust device is arranged on the fuselage, and an air suction type electric propulsion device is adopted as the thrust device. The annular truss type photoelectric conversion device is used, the design of the large unfolding and folding ratio of the solar thin film can be achieved, meanwhile, the structure is simple, and the structural mass can be effectively reduced.
