The invention discloses a variable unmanned aerial vehicle. The variable unmanned aerial vehicle comprises a vehicle body (1), multi-section wings (2) and an empennage (3). The multi-section wings (2) are arranged on the vehicle body (1), the adjacent wing sections of the multi-section wings (2) can relatively stretch out and draw back, and therefore the total elongation of the multi-section wings (2) is changed. The empennage (3) is arranged on the vehicle body (1), and can be far away from or close to the vehicle body (1) relative to the flying direction of the unmanned aerial vehicle. All the wing sections of the variable unmanned aerial vehicle can relatively stretch out and draw back, and therefore the elongation of the wings is changed. When the wing sections relatively stretch out and draw back to change the pneumatic appearance of the variable unmanned aerial vehicle, the gravity center position and the pneumatic characteristic changed by stretching out and drawing back of the wings are adjusted by enabling the empennage to be far away from or close to the vehicle body (1) relative to the flying direction of the unmanned aerial vehicle, and therefore the pneumatic appearance of the variable unmanned aerial vehicle is kept at the optimal state whether the variable unmanned aerial vehicle is in any state.
