Problems solved by technology

Japan proposed the concept of using multiple satellites to drag the film around to build a space giant surface. It listed four satellites of 1 ton each to pull a film with a size of 500 meters square, a film thickness of 5 microns, and a mass of 2.5 tons. The simulation analysis of dynamic control has been carried out. However, the forming and control of this method is technically difficult and poor in feasibility.

Abstract

The invention discloses a space tethered unfoldable covered surface system which mainly solves the problems of difficult unfolded formation and poor stability in the prior art. The space tethered unfoldable covered surface system comprises soft traction cables (1), a traction cable control mechanism (3), folded rings (4) and connection joints (5). Soft screen meshes (8) are bonded on rigid structures formed by the folded ring and the connection joints to form covered surfaces (2), and the soft traction cables (1) are connected with the covered surfaces (2) and the traction cable control mechanism (3) which controls the soft traction cables (1) to stretch out and draw back. Tension springs (6) and traction cables (7) are arranged in the folded rings (4), the tension springs (6) are stretched out when the folded rings (4) are folded, and when the folded rings (4) are unfolded, the tension springs (6) draw back, and the traction cables (7) are shortened. Under the effect of the tension of the traction cables, the connection joints (5) are unfolded to enable the covered surfaces to be unfolded into a horizontal working state from a vertical folded state, and the folded rings are locked through positioning devices on the connection joints (5). The space tethered unfoldable covered surface system has the advantages of being low in surface density, high in configuration actuary, large in storage rate and stable in posture, and can serve as an unfoldable screening device in the space.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and specifically relates to a space tether expandable shielding surface system, which can be used in space large-scale expandable systems such as space sunshades, space shielding surfaces, space mirrors, and space solar power stations. Background technique [0002] The outer space of the earth has brought great opportunities and challenges to human new technological development and technological progress. With the continuous enhancement of human space carrying capacity and the continuous development of space technology, the application of space super-large expandable structures is gradually put on the agenda. Space super-large deployable structures have direct application prospects in the field of space communication, and have produced huge economic and social benefits. Space super-large expandable structures also have attractive application prospects in other fields, such as space sunlight r...
