Automatic docking and falling connector with active follow-up function of carrier rocket

Abstract

The invention discloses an automatic docking and falling connector with an active follow-up function of a carrier rocket. The connector comprises an executing mechanism, signal detection devices, an error compensation mechanism and a locking device; a base frame of the executing mechanism is fixedly connected with oscillating bars stretching out from a carrier rocket launch tower, the circumferential direction of the base frame is symmetrically provided with hydraulic cylinders, and the cylinder bodies of the hydraulic cylinders are fixedly connected with the base frame; the ends of piston rods of the hydraulic cylinders are fixedly connected with sliding blocks, the sliding blocks are connected with the error compensation mechanism through connecting rods, and the connecting rods are connected with the sliding blocks and the error compensation mechanism through spherical hinges; the signal detection devices are arranged at the upper end and lower end of the base frame and are corresponding to the positions of protruding marks on a rocket body, the protruding marks at the two ends are mutually perpendicular, one protruding mark is parallel to the axial direction of the rocket body, and the extension line of the protruding mark penetrates the charging valve center line of the rocket body. The automatic docking and falling connector with the active follow-up function of the carrier rocket can reduce the force borne by the rocket body and shorten the docking and falling time.

Description

technical field [0001] The invention belongs to the technical field of carrier rocket propellant filling, in particular to a carrier rocket automatic docking and shedding connector with an active follow-up function. Background technique [0002] During the process of propellant filling, the launch vehicle will vibrate slightly under the influence of wind load. If the docking and disengagement mechanism is rigidly connected with the connector on it and the umbilical tower, it will cause a gap between the stationary connector and the swinging rocket body. "tear" each other, resulting in a large force, affecting the reliability and sealing of the connection, and in severe cases, it will cause medium leakage. At present, the domestic practice is to use a passive follow-up method to solve this problem. When passive follow-up is used, after the connector panel is docked and locked with the rocket valve panel, it must first be disconnected from the body of the docking and falling ...

AI Technical Summary

Problems solved by technology

The structure of the passive servo system is complicated, and it takes a long time to complete a working cycle. Obviously, it does not meet the requirements of rapid launch of the rocket, and it is more prone to failure.
