Abstract

The invention provides a turbine damper for unmanned aerial vehicle blocking, and belongs to the technical field of unmanned aerial vehicle blocking. The turbine damper comprises a turbine damper body, a brake belt wheel and a pull-out seam, wherein the brake belt wheel is connected to the turbine damper body and is used for bearing and rolling a brake belt, and the pull-out seam is arranged on the brake belt wheel and is used for allowing one end of the brake belt to be pulled out towards the outside of the brake belt wheel. By pulling the brake belt into or out from the pull-out seam, the length of the brake belt wound around the brake belt wheel can be adjusted, by adjusting the length of the brake belt on the brake belt wheel, the winding radius of the brake belt wheel is changed, thedamping force on the brake belt under different working conditions can be adjusted, so that the turbine damper can be suitable for the unmanned aerial vehicle blocking under the different working conditions; when the brake belt is wound and pulled out, the pull-out seam plays a role in fixing, and prevents the slippage between the brake belt and the brake belt wheel; and under special conditions,the redundant brake belt can be pulled into the pull-out seam again, so that the risk of the pulling an unmanned aerial vehicle forcibly is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a turbine damper for unmanned aerial vehicles. Background technique [0002] In the field of fixed-wing unmanned aerial vehicle (UAV) recovery, runway rolling and arresting recovery is a commonly used method. The unmanned aerial vehicle first lands on the runway and rolls forward at high speed. The arresting hook set at the tail of the drone hooks the arresting cable, and finally the arresting cable drives the damper to consume the kinetic energy of the drone. [0003] The turbine damper for runway roll in the prior art generally includes the main body of the turbine damper and the brake belt shaft; after the arresting hook hooks the arresting cable, the UAV drags the arresting cable to drive the brake belt to move forward at high speed, and the brake belt drives the turbine The damper rotates at high speed, and the blades of the rotor stir the liquid in the inn...
