Solar unmanned aerial vehicle

Abstract

The invention relates to the design of unmanned aerial vehicles, in particular to a solar unmanned aerial vehicle. The solar unmanned aerial vehicle comprises an unmanned aerial vehicle body and rotors; the unmanned aerial vehicle body is in a shape of a rectangular plate; the rotors are uniformly distributed at four corners of the unmanned aerial vehicle body; the rotors are positioned within a plane parallel to the upper surface of the unmanned aerial vehicle body; and a solar cell panel for providing electric energy for the rotors is laid on the upper surface of the unmanned aerial vehiclebody. According to the solar unmanned aerial vehicle, the structure is compact; higher rigidity is very likely to realize; the aerodynamic characteristics are more stable; the flight control is more reliable; in addition, vertical take-off and landing and hovering functions can be realized; furthermore, the solar unmanned aerial vehicle has the advantage of a flying wing-type aircraft; the flyingspeed and trajectory can be effectively controlled by using an aerodynamic force; and moreover, the solar energy utilization efficiency of the solar unmanned aerial vehicle is higher.

Description

technical field [0001] The invention relates to the design of an unmanned aerial vehicle, in particular to a solar-powered unmanned aerial vehicle. Background technique [0002] Unmanned Aerial Vehicle (UAV) is a kind of aircraft with a wide range of applications. For example, my country's Dajiang Corporation (DJI) produces multi-axis (four-axis, six-axis) rotor drones of various specifications, which are mainly used for entertainment or aerial photography. Most of the small UAVs use batteries to provide energy, and the flight time is generally tens of minutes, and the longest is several hours. [0003] In order to obtain a longer-term energy supply, there is a research direction considering how to use solar energy as an energy source for light aircraft, with the goal of achieving flight across the day and night in the atmosphere. Among them, the most successful case is the "Sunshine Impulse 2" solar-powered manned aircraft. The aircraft has successfully achieved 118 hour...
