Inflatable Support Ring for Spaceborne Radial Rib Inflatable Deployable Antenna

Abstract

An inflatable support ring for a space-borne radial rib inflatable deployment antenna belongs to the field of space-borne antenna technology and solves the problems existing in a space-borne radial rib inflatable deployment antenna. A connecting pipe is set between two adjacent straight pipes to connect the two straight pipes, and a main adhesive tape is set on the outside of each connecting pipe to surround one-half of the circumference of the connecting pipe. The length of the connecting pipe is equal to the length of the main adhesive tape. The width of the buckle is less than five millimeters larger than the width of the main hook and loop, and one or more auxiliary hook and loop are arranged on both sides of the main hook and loop, which can strengthen the connection of the main hook and loop, and the auxiliary hook and loop Both the belt and the main hook and loop are on the fluffy surface or both are on the hooked surface; the invention is used for space-borne radial rib inflatable deployment antennas.

Description

Technical field [0001] The invention belongs to the technical field of satellite-borne antennas, and particularly relates to an inflatable support ring used for a satellite-borne radial rib inflated and deployed antenna. Background technique [0002] The reflective surface of the satellite-borne radial ribs inflatable deployment antenna is mainly supported by the radial ribs and the inflatable support ring. The inflatable support ring is a near-circular shape formed by connecting multiple straight pipes end to end in turn. Multiple radial ribs are glued together. The buckle is connected to the inflatable support ring. Since the middle part of each straight tube forming the inflatable support ring is easily deformed when it is pulled, the hook and loop must be connected at the junction of two adjacent straight pipes, but the two adjacent straight pipes The outer side of the transfer position of the tube is a sharp-angle structure, which causes the hook and loop fastener to easily ...

AI Technical Summary

Problems solved by technology

[0002] The reflective surface of the space-borne radial rib inflatable deployment antenna is mainly supported by the radial rib plate and the inflatable support ring. The buckle is connected with the inflatable support ring. Since the middle part of each section of the straight pipe constituting the inflatable support ring is easily deformed when subjected to tension, the hook and loop must be connected at the junction of two adjacent straight pipes. However, the two adjacent straight pipes The outer side of the pipe junction is a sharp-edged structure, which causes the Velcro to be easily displaced during deflated folding and inflated deployment, thereby causing displacement or deformation of the radial ribs and reducing the accuracy of the reflective surface, especially the deflection. The feed antenna uses an oval inflatable support ring, and the displacement of the hook and loop is more obvious
