A kind of wind damping device applied to aviation dragging system

Abstract

The invention discloses a wind force damping device, and belongs to the field of damping devices in an aviation drag system. The wind force damping device comprises air inlet dampers, fan impellers, an impeller shaft, exhaust air dampers, a cabin body, a decoy, a traction cable, a transmission steering device and an impeller shaft support, wherein the air inlet dampers are arranged at the front end of the cabin body; the fan impellers are arranged at the rear end of the air inlet dampers; one end of the impeller shaft is connected with the fan impellers and the other end of the impeller shaftis connected with the transmission steering device; the impeller shaft is fixed to the impeller shaft support; two ends of the impeller shaft are fixed to the cabin body; the decoy is released and isconnected with the transmission steering device through the traction cable, and the fan impellers are driven to rotate through the impeller shaft; and the air inlet dampers and the exhaust air dampersare opened at the same time, so that airflow which acts on the surfaces of the fan impellers is formed, torque for allowing the fan impellers to reversely rotate is generated, and the decoy can be decelerated or recovered. According to the wind force damping device disclosed by the invention, by using the wind force simply, the damping effect of slowing down the releasing speed of the traction cable can be generated and the situation that the traction cable is broken by pulling at the end of releasing can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of design of damping devices in aviation dragging systems, and in particular relates to a wind damping device. Background technique [0002] At present, towed decoys are usually installed on advanced fighter jets at home and abroad, the purpose is to interfere with radar-guided missiles and make them deviate from the target, so as to ensure the safety of the airborne platform. However, in the process of use, it was found that after the bait bomb was thrown, affected by its own gravity and air resistance, the speed of the bait bomb was getting faster and faster. was pulled off. [0003] In order to solve this problem, the release speed of the traction rope is usually controlled by adding a brake motor device, an inflatable air bag device, and the like. However, the brake motor scheme has too complicated device structure, which greatly increases the structural weight of the system; and the inflatable airbag ...

AI Technical Summary

Problems solved by technology

However, for the brake motor solution, the structure of the device is too complicated, which greatly increases the structural weight of the system; and the inflatable airbag solution also has the disadvantage that the airbag needs to be replaced frequently due to wear and tear.
