Solar unmanned aerial vehicle route planning method based on day and night cycle flight

Abstract

The invention discloses a solar unmanned aerial vehicle route planning method based on day and night cycle flight, and belongs to the technical field of route planning. According to the method, firstly the physical parameters of the flight environment and a solar unmanned aerial vehicle are initialized, then the sun position change data under different moments of the specific date are calculated, the output power of laid photovoltaic modules is calculated when the unmanned aerial vehicle is in different flight attitudes under different sun positions, the corresponding optimal flight attitude is calculated according to the sun position of different moments, and the daytime flight route of the solar unmanned aerial vehicle is formed and the night flight route is calculated according to the flight attitude of different moments. The endurance time of the unmanned aerial vehicle can be enhanced to the greatest extent so that the threshold of realizing day and night flight of the solar unmanned aerial vehicle can be reduced and the subsequent design of the load module can be facilitated. With application of the method, the night flight route can be rapidly and effectively obtained so as to meet and realize the requirement of day and night cycle flight of the solar unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of track planning, and relates to a flight strategy of a solar unmanned aerial vehicle and a track optimization system, in particular to a track planning method for a solar unmanned aerial vehicle based on day-night cycle flight. Background technique [0002] Solar-powered Unmanned Aerial Vehicles (SUAV for short) is an unmanned aerial vehicle that uses solar energy as the main energy source and uses energy storage batteries to supply power to maintain the flight of the drone to the maximum extent. Solar-powered UAVs have long cruising time, high flying altitude, and wide coverage, which have irreplaceable advantages of conventional aircraft. The research on solar-powered aircraft is a new field focused on the development of my country's aviation industry in the new century, and it is also a major research hotspot in my country's aviation industry. [0003] The current solar unmanned aerial vehicles mainly ...

Problems solved by technology

[0008] At present, the research on the trajectory planning algorithm of solar unmanned aerial vehicles mainly solves the trajectory from the starting point to the ending point with the maximum energy gain by given some physical parameters of the aircraft, given the starting point and the ending point. However, in the above research, the researchers The assumed conditions are relatively rational, and there is a certain gap between them and the actual situation. The trajectory of solar drones is rarely planned for the actual day and night environment.
