Box type solar unmanned aerial vehicle

Abstract

The invention provides a box type solar unmanned aerial vehicle which comprises an unmanned aerial vehicle body, box type wings, composite type vertical fins, a ducted fan assembly, rotor assemblies,an undercarriage and solar panels. The unmanned aerial vehicle adopts a box type wing layout, the laying area of the solar panels is increased, and meanwhile, the cruising aerodynamic efficiency of the solar unmanned aerial vehicle is improved; the mode that a ducted fan and tilting rotors are combined is adopted, so that it is guaranteed that the solar unmanned aerial vehicle has the vertical take-off and landing performance and the cruising performance; and the mode of the composite type vertical fins is adopted, so that the stability and controllability of the solar unmanned aerial vehicleare guaranteed, and meanwhile, the influence on the wing aerodynamic efficiency of the solar unmanned aerial vehicle by tilting rotor wake flows in the cruising process is reduced.

Description

technical field [0001] The invention relates to the field of UAV design, in particular to a box-type solar-powered UAV that combines solar panels with a box-type wing layout and has both vertical take-off and landing and cruise performance. Background technique [0002] Solar UAV is a new type of energy UAV. Because it can convert sunlight into UAV's power energy by laying solar sheets, and then increase the UAV's range and flight time, so it is in Both military and civilian fields have important market application value. It can be used for reconnaissance and patrol in the military, and it can be used for supervision and signal connection in civilian use. However, most solar-powered UAVs currently use a fixed-wing layout. This UAV layout requires a runway when flying forward and landing. , the runway distance greatly limits the scope of use of this type of solar-powered UAV. In order to solve this problem and meet the needs of the market, it is particularly important to des...

Problems solved by technology

It can be used for reconnaissance and patrol in the military, and it can be used for supervision and signal connection in civilian use. However, most solar-powered UAVs currently use a fixed-wing layout. This UAV layout requires a runway when flying forward and landing. , the runway distance greatly limits the range of use of this type of solar-powered UAV. In order to solve this problem and meet the needs of the market, it is particularly important to design a solar-powered UAV with both vertical take-off and landing and cruise performance.

[0003] Chinese invention patent CN 108557081 A discloses "a solar-powered connected-wing unmanned aerial vehicle and its control method", which mainly includes: tail struts, wings and pod components, which are mainly used to solve the problem of unmanned vehicles with large aspect ratio The structural strength of the solar-powered UAV is poor, the design is difficult, and the existing UAV is simply controlled by a motor, which cannot cooperate with the steering gear to achieve comprehensive control. Although the solar-powered UAV has advantages in control, it cannot achieve vertical take-off and landing, which greatly Limit the scope of use of the solar drone;

[0004] Chinese invention patent CN 108116656 A discloses "a solar-powered unmanned aerial vehicle". The unmanned aerial vehicle includes a fuselage, wings and solar panels. Wing ribs, spars and longitudinal walls are closely combined to form a sandwich structure with strong vibration and impact resistance; solar panels are embedded in flexible fillers, and the wing structure absorbs vibrations and impacts, greatly reducing the impact of solar panels. Fragmentation and damage, thereby improving the service life of solar panels, but the solar drone does not have vertical take-off and landing performance, and its application market will be reduced
