The invention provides a vertical take-off and landing type fixed-wing unmanned aerial vehicle. The vertical take-off and landing type fixed-wing unmanned aerial vehicle comprises a vehicle body, wherein a forwarding drive is arranged on the vehicle body, wings are arranged at two sides of the vehicle body, a foldable vehicle body rotor wing is arranged in the vehicle body, vehicle body sliding plates are arranged at two sides of the foldable vehicle body rotor wing, a plurality of foldable rotor wings of the wing are arranged in the wing, and an openable wing sliding plate device is arranged at the top part of the rotor wing of the wing. With adoption of the above structure, the vertical take-off and landing type fixed-wing unmanned aerial vehicle has the following beneficial effects that the forwarding drive and the vehicle body rotor wing are combined with the rotor wings of the wing to conveniently realize switching between the vertical take-off and landing mode and the fixed wing flight mode; the unmanned aerial vehicle can hover at any time when performing a task so as to make a camera observe at a fixed point, and does not require a runway and ejection equipment when taking off and landing; the vehicle body rotor wing is combined with the rotor wings of the wing to conveniently control the balance of the whole vehicle; the hidden vehicle body rotor wing and the rotor wings of the wing are adopted to make no interference between the vertical take-off and landing mode and the fixed wing flight mode, and the volume of the wing is not required to be increased; and the air stream lifting efficiency is high.
