Problems solved by technology

Due to the influence of the airflow during the flight of the helicopter, the airdrop model itself will rotate, which will cause the cable of the pull switch to be entangled, and may even lead to the opening of the pull switch, and the wrong activation of the recovery control device, resulting in the failure of the airdrop test.

Embodiment

[0037] In the development process of the spacecraft recovery and landing system, airdrop tests are generally used to verify the performance of parachutes and related products. The derotation device of the present invention adopts a simple structural mechanism design, and the rotation elimination between the pull-out switch cable and the airdrop model is realized by setting a turntable 3 that can rotate around the parachute extractor 6 on the separation surface of the parachute extractor 6 .

[0038] Fix the pull switch cable in a circular hole of the turntable 3. When the airdrop model is disturbed by the airflow and rotates, the pull switch cable will drive the turntable 3 to rotate with the outer ring of the bearing 2, so that the pull switch wire There is no relative rotation between the cable and the airdrop model to achieve the function of preventing cable entanglement.

Abstract

The invention provides an air drop rotation removing device. The rotation removing device is mounted on one side of a separation surface of a parachute separating unit, a bearing is mounted in the rotation removing device, a rotary table used for being connected with a pull pin switch cable is arranged on the outer side of the bearing, and the pull pin switch cable is changed to be connected to the rotary table from being directly connected to the separation surface of the parachute separating unit. When an air drop model rotates, the pull pin switch cable can drive the rotary table on the outer side of the rotation removing device to rotate together with a bearing outer ring, so that relative rotation does not occur between the air drop model and the pull pin switch cable, and the occurrence of winding is avoided.

Description

technical field [0001] The invention relates to an air-drop anti-rotation device and an anti-parachute device with anti-rotation function, which belong to the space vehicle recovery and landing test technology. Background technique [0002] In the development process of the spacecraft recovery and landing system, airdrop tests are generally used to verify the performance of parachutes and related products. Such as figure 1 As shown, in the airdrop test, the airdrop model simulating the return capsule is hung under the helicopter, connected with the parachute remover, and the pull switch cable for starting the recovery control device is connected between the upper part of the detachment surface of the parachute remover and the airdrop model . Due to the influence of the airflow during the flight of the helicopter, the airdrop model itself will rotate, which will cause the cable of the pull switch to be entangled, and may even lead to the opening of the pull switch, and the ...
