Research on an Unmanned VTOL Fixed Wing UAV System and Its Application

Aiming at the existing operation mode of VTOL fixed wing UAV, this paper proposes an unattended operation mode that equipping the VTOL fixed-wing UAV with intelligent apron, autonomous charging and power off device, high-precision take-off and landing device, automatic recovery device, meteorological monitoring device, 4G remote communication module and Monitoring software. To operate the VTOL fixed-wing UAV without personnel on site. Based on this unattended operation mode, this paper proposes seven kinds of application inspection modes. According to different application environments, a reasonable practical application scheme can be achieved by reasonably adjusting the ratio of UAV and intelligent apron according to equipment operation time, operation interval, operation frequency and operation scope. At the same time, the flight test was carried out in the application environment of expressway, and the test results reached the expected design indexes, which laid the foundation for the system to the application environment of large area and long distance.
