Space docking error compensation mechanism of carrier rocket connector system

Abstract

The invention discloses a space docking error compensation mechanism of a carrier rocket connector system. The space docking error compensation mechanism comprises a valve panel, a connector panel, a suspension platform and two groups of spring guiding rods, wherein the valve panel is matched with a rocket body and is provided with a centering guide hole; one end of the connector panel is provided with a centering guide device; the suspension platform is matched with an actuator; the two groups of spring guiding rods are arranged between the connector panel and the suspension platform and are connected with the connector panel and the suspension platform through spherical hinges, the spring guiding rods of each group are of symmetrical arrangement, and the two groups of spring guiding rods are of rectangular-pyramid type suspended arrangement. According to the space docking error compensation mechanism, the actuator and the connector panel can be flexibly connected, small angle difference and position difference resulting from the swing and torsion of the rocket body are compensated during docking, following and shedding, the tracking error of the actuator is compensated, the stress of the rocket body is reduced, and the degree of automation of the connector system is increased.

Description

technical field [0001] The invention belongs to the technical field of launch vehicle ground filling equipment, in particular to a space docking error compensation mechanism for a launch vehicle connector system. Background technique [0002] The United States has conducted in-depth research on fast docking and zero-second drop-off separation in the aspect of the connector of the launch vehicle ground filling system, and has formed the "Arrow Habitat" docking technology. During the docking and filling process, the valve and the connector are in a relatively static state. It avoids the difficulty of centering and follow-up due to the swing of the rocket body with the wind during the docking and filling process, but this difficulty cannot be avoided in China; at the same time, the docking process requires manual assistance. If the connector is automatically separated before the rocket is launched, Once the launch operation is canceled for some reason, the connector cannot be r...

[0002] The United States has conducted in-depth research on fast docking and zero-second drop-off separation in the aspect of the connector of the launch vehicle ground filling system, and has formed the "Arrow Habitat" docking technology. During the docking and filling process, the valve and the connector are in a relatively static state. It avoids the difficulty of centering and follow-up due to the swing of the rocket body with the wind during the docking and filling process, but this difficulty cannot be avoided in China; at the same time, the docking process requires manual assistance. If the connector is automatically separated before the rocket is launched, Once the launch operation is canceled for some reason, the connector cannot be re-docked with the rocket body valve in a short time to ensure the reliability of the seal; at the same time, the connector system is attached to the rocket body during filling, which increases the extra load
