Novel tethered unmanned aerial vehicle

Abstract

The invention discloses a novel tethered unmanned aerial vehicle, which comprises an airframe structure, an airframe power supply device, a power device, a measurement and control device, a mooring device and a task load device. The airframe structure comprises a suspension arm, a center box and a landing support device, which are used for carrying and installing the on-board task equipment, the power equipment and the measurement and control equipment of the new-type tethered unmanned aerial vehicle. The airframe power supply equipment is used for supplying electric power; Power equipment includes propellers, motors and electrically regulated mooring to provide the lift required by the tethered UAV and the steering force required for the control of the tethered UAV platform. Power equipment provides power for the tethered UAV during the lift-off, hover and recovery phases. Measurement and control equipment includes GPS, optical terminal computer, flight control unit, which has flightcontrol function, parameter measurement function, time synchronization function and data transmission function. Mooring equipment includes guide pulleys, lifting platforms and cable storage drums, which are used for power supply, lift-off, site recovery, off-site transportation, commissioning and maintenance of moored UAVs.

Description

technical field [0001] The invention relates to the field of overall design of tethered balloons or multi-rotor UAVs, in particular to a novel tethered UAV. Background technique [0002] The tethered balloon is a kind of buoyancy generated by the lighter-than-air gas that is filled into the airbag, and overcomes its own weight to achieve buoyancy in the air. , relying on multi-functional cables to achieve long-term fixed-point stay in the air, and can control its floating height in the atmosphere. During the inflation process, relatively complete inflation equipment is required, which covers a large area, and the system takes a long time to deploy and requires more personnel. For rotor UAVs, although it has the advantages of vertical take-off and landing, simple structure, and easy maintenance, etc. , but the rotor UAV has shortcomings such as relatively short space time and weak load capacity. [0003] The new tethered UAV inherits the design concept of the tethered ballo...
