The invention discloses a buoyancy assisted lifting type unmanned aerial vehicle. The buoyancy assisted lifting type unmanned aerial vehicle comprises an unmanned aerial vehicle body (1), a controller, an electronic speed regulator, multiple supporting arms (4) and a rotor wing assembly, wherein the rotor wing assembly comprises a rotor wing (11), a rotor wing input shaft, a rotor wing mounting base (6), an air bag device controlled by the controller, a driving mechanism for driving the rotor wing (11) to rotate, and an angle adjusting mechanism for adjusting the angle of pushing force of the rotor wing (11); the air bag device comprises an air bag (2) folded into the inner cavity of the unmanned aerial vehicle body (1) and a gas filling device, the air bag (2) is transversely arranged right above the unmanned aerial vehicle body (1) after being opened; and the angle adjusting mechanism comprises a first adjusting mechanism for driving the rotor wing (11) to rotate circumferentially along the axis of the supporting arm (4) and a second adjusting mechanism for driving the rotor wing (11) to swing slightly along the axis perpendicular to the supporting arm (4) within a range from 0 degree to 40 degrees. The buoyancy assisted lifting type unmanned aerial vehicle has relatively strong cruising ability and can be operated relatively flexibly.
