The invention discloses a vertical take-off and landing fixed wing unmanned aerial vehicle which comprises a vehicle body, wings and a vertical take-off and landing system, wherein the vehicle body and the wings are combined. The wings comprise a pair of wings located on the left side and the right side of the vehicle body, lower single wing arrangement is adopted, and the upper-turned angle ranging from 3 degrees to 10 degrees is formed between the lower plane of each wing and the horizontal plane. The vertical take-off and landing system comprises hanging frames symmetrically arranged below the wings and propellers arranged on the hanging frames. According to the provided technical scheme of the embodiment, the wing and body combination arrangement is adopted by the unmanned aerial vehicle, the interference drag is greatly reduced, meanwhile, the inner space of the vehicle body is increased, and the bearing capacity is improved; the lower single wing arrangement is adopted by the wings, the upper-turned angles are formed, the wings are combined with the lower hanging type vertical take-off and landing system, so that the lift force of the vertical take-off and landing system and the gravity of the unmanned aerial vehicle are distributed triangularly, and the vertical take-off and landing stability of the unmanned aerial vehicle is improved; the pneumatic influence on the wing and body combination vehicle body is small, the characteristic of the high lift-drag ratio of the wing and body combination vehicle body is brought into full play, and the pneumatic performance of the unmanned aerial vehicle is improved.
Description
technical field [0001] The present disclosure generally relates to the technical field of aviation vehicles, in particular to an unmanned aerial vehicle, and in particular to a fixed-wing unmanned aerial vehicle with vertical take-off and landing. Background technique [0002] Fixed-wing UAVs are characterized by long flight times and large flight radii, which perfectly match the needs of the logistics and transportation fields. However, the take-off distance of fixed-wing aircraft is very long, and the required take-off environment is relatively harsh, which limits its large-scale application. The vertical take-off and landing fixed-wing UAV not only retains the advantages of the long-endurance and long-flight radius of the fixed-wing aircraft, but also has very loose requirements on the take-off environment, and has the value of being widely used in commercial and civilian applications. [0003] The existing vertical take-off and landing fixed-wing unmanned aerial vehicle...
