Problems solved by technology

But it also has obvious deficiencies: First, the four-rotor component does not work in level flight, which becomes dead weight, reduces the load capacity of the UAV, increases the resistance of the whole aircraft, and has a relatively large decrease in cruising speed and endurance time. The second is that the fixed-wing components do not work when hovering, so that the control of the UAV is completely dependent on the rotor, and the aerodynamic structures such as the main wing and tail are prone to generate large aerodynamic moments under external interference, which is prone to insufficient rotor control margin. question

Abstract

The present invention is applicable to the technical field of unmanned aerial vehicle control, and provides a four-engine double-arm vertical take-off and landing unmanned aerial vehicle and its flight control method, comprising: the left-hand arm is arranged at the left front middle part of the main wing, and is fixed with the left-hand arm drive mechanism Connected, forming a cross structure with the main wing, rotating 90° during flight; Rotate 90° during the process; No. 1 power assembly and No. 2 power assembly are respectively fixedly connected to the left and right ends of the left arm, and No. Ends. The UAV provided by the invention can take off and land vertically, which reduces the requirements for take-off or recovery sites. The structure is simple and easy to control. High efficiency, long cruising time and fast cruising speed.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle structure design and unmanned aerial vehicle control, and in particular relates to a four-engine double-rotary-arm vertical take-off and landing unmanned aerial vehicle and a flight control method thereof. Background technique [0002] Now drones are more and more widely used in aerial surveying and mapping, power inspection, express delivery, disaster prevention and mitigation, military reconnaissance and other fields. Among them, the widely used models include: fixed-wing drones, multi-axis rotor drones Human-machine and fixed-wing-four-rotor composite UAVs, but these types of UAVs are always facing some difficult contradictory problems while greatly improving the operating efficiency of the applied industries: [0003] Fixed-wing UAVs have mature technology, high aerodynamic efficiency, long battery life, fast cruising speed, and large operating area per sortie, but the traditio...
