Aerodynamic layout of large solar unmanned aerial vehicle

The invention belongs to the field of large solar unmanned aerial vehicles, and relates to an aerodynamic layout of a large solar unmanned aerial vehicle, which comprises a fuselage and deformable wings, and the deformable wings comprise outer wings and inner wings; when the rotating shafts on all the fuselages deflect to the maximum angle, the ground sliding state of the solar unmanned aerial vehicle is achieved, and sliding and other operations of the unmanned aerial vehicle are facilitated; when the rotating shafts on all the fuselages deflect to a proper angle, the wing direction size of the solar unmanned aerial vehicle can be adjusted at the moment, a runway can be fully utilized, the lift force characteristic is considered, the take-off and landing performance can be improved, and the state is called the take-off and landing sliding state of the solar unmanned aerial vehicle; when the rotating shafts on all the fuselages deflect to the minimum angle, the extension length of the whole aircraft is contro
