Spacecraft dust cover and manufacturing method and using method thereof

Abstract

The invention relates to a spacecraft dust cover and a manufacturing method and a using method thereof, the spacecraft dust cover is of a spiral winding structure formed by winding a thin and narrow long-strip-shaped structure, the spacecraft dust cover has a mounting state and an unfolding state, in the mounting state, the spacecraft dust cover is wound to form the spiral winding structure, and in the unfolding state, the spacecraft dust cover is wound to form the spiral winding structure. The light guide plate is mounted at a light inlet of a spacecraft in an interference fit manner; in the unfolding state, the spacecraft dust cover is unfolded to form the thin and narrow long-strip-shaped structure, the spacecraft dust cover is manufactured in an overall cutting mode, the structure is simple, manufacturing is easy, compressible pre-tightening installation can be achieved, the spacecraft dust cover is suitable for on-satellite dust prevention of a spacecraft, and good sealing and dust prevention performance is achieved; the dust cover for the spacecraft can be unfolded into a flexible thin and narrow long-strip-shaped structure by pulling the pulling rope, so that the dust cover for the spacecraft is convenient to disassemble and assemble and can be disassembled from the satellite only through a very small disassembling opening.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a spacecraft dust cover and a method for making and using the same. Background technique [0002] At present, aerospace remote sensors have been widely used in many fields such as earth resource census, topographic mapping, ocean research, and weather forecasting. Most spacecraft, especially high-precision optical remote sensors, have very strict requirements on excess objects and dust inside the instrument, and need to be strictly controlled during the ground development process, usually by installing a dust cover for protection. In general occasions, an integral dust cover with a certain rigidity can be used, which is easy to install and has strong protective ability; in the launch preparation stage, after the spacecraft is installed on the satellite platform, since the spacecraft will generally be surrounded by the satellite platform, if To use the integral rigid dust cove...

AI Technical Summary

Problems solved by technology

In general situations, an integral dust cover with a certain rigidity can be used, which is easy to install and has strong protection capabilities; in the launch preparation stage, when the spacecraft is installed on the satellite platform, since the spacecraft is generally surrounded by the satellite platform, if To use an integral rigid dust cover, it is necessary to reserve a large disassembly port on the satellite platform, and because of the small operating space, it is very difficult to disassemble the dust cover. If the dust cover cannot be removed smoothly, it will lead to Serious consequences such as launch delays
