Abstract

The invention discloses a combined type vertical take-off and landing long-endurance electric unmanned aerial vehicle, which belongs to the field of unmanned aerial vehicles. According to the combined type vertical take-off and landing long-endurance electric unmanned aerial vehicle, the fuselage adopts the wing body fusion body, the wetted area of the unmanned aerial vehicle can be reduced by removing unnecessary exposed parts of the fuselage, so that the frictional resistance is reduced, and the lift-drag ratio of the unmanned aerial vehicle is increased by reducing parts irrelevant to lift force in the wing body fusion layout. The winglet is adopted, the end plate effect of the winglet is utilized, and the equivalent aspect ratio of the aircraft is increased under the condition that the wingspan increase is small. The double-tail-boom empennage layout is adopted, the lateral stability of the unmanned aerial vehicle can be improved, and the structural support is good. The lift-drag ratio aerodynamic layout is improved through the structural design of the unmanned aerial vehicle, so that the endurance performance of the aircraft is improved.
