Abstract

The invention provides a turbine damper used for blocking drones, belonging to the technical field of drone blocking, comprising: a turbine damper body; a brake pulley, which is connected to the turbine damper body and used for winding the brake strip; , set on the brake pulley, used to pull out one end of the brake belt towards the outside of the brake pulley, and by pulling the brake belt in or out from the pull-out slot, to adjust the brake belt that can be placed on the brake pulley. Length; by adjusting the length of the brake belt on the brake pulley, the winding radius on the brake pulley is changed, and the damping force on the brake belt can be adjusted under different working conditions, so that the turbine damper can be applied to different working conditions. The blocking of drones; when the brake belt is wound and pulled out, the pull-out seam plays a fixed role to prevent slippage between the brake belt and the brake pulley; in special cases, the excess brake belt can be drawn in again through the pull-out seam Avoid the danger of deadlifting the drone.

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...
