Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a large tilt-rotor vertical take-off and landing fixed-wing unmanned aerial vehicle and its onboard avionics system. Background technique [0002] Tilt-rotor vertical take-off and landing fixed-wing (referred to as tilting) UAV is a new type of UAV that integrates fixed-wing and helicopter. The UAV can take off vertically without relying on the runway. After flying to high speed, the rotor pull can tilt forward 90°, so as to fly at high speed like a fixed wing. When returning to land, the rotor pull can tilt up 90° to land vertically like a helicopter. At present, the size of the common tilting and hanging UAVs is generally small, and the wingspan is not more than 3 meters. There are no more than 16, and generally they can be directly controlled by the PWM signal output by the flight controller. The avionics system of the whole machine is relatively simple, and ...

AI Technical Summary

Problems solved by technology

[0003] When the tilt-rotor vertical take-off and landing fixed-wing unmanned aerial vehicles (UAVs) become larger and larger, the functions become more and more complex, and the safety level requirements become higher and higher, which leads to an increasing number of avionics equipment for the UAV. Therefore, for The control method of the UAV is no longer a single PWM signal, and there will also be the problem of long cable wiring, and the requirements for weight control and anti-electromagnetic interference will become more and more stringent. The system can no longer meet this demand
