Problems solved by technology

[0003] In order to solve the problems of high weight, low folding efficiency and inability to construct large-scale space structures existing in the existing mechanical expansion structures, the present invention provides an inflatable expansion support rod for ultra-long space, which is mainly constructed of film materials. The invention includes an inner tube, an outer tube and two cylindrical end caps, the inner tube is placed in the outer tube, each end cap has an air-filling hole in the center, and the two end caps are connected with the inner layer respectively. The two ends of the tube and the outer tube are sealed and connected; the length L of the support rod is 10-100m; the inner tube and the outer tube are made of film material

Abstract

The present invention relates to an ultralong space inflated spread supporting bar. It includes an inner layer tube and an outer layer tube, the inner layer tube is placed in the interior of said outer layer tube, it also includes two end head covers, every end head cover centre is equipped with an air-charging hole, two end head covers are respectively and fixedly connected with two ends of inner layer tube and outer layer tube, the length of said supporting bar is 10-100 m, and the inner layer tube and the outer layer tube are made up by using film material. Said invention also provides its extensive application field.

Description

technical field [0001] The present invention relates to a deployment structure for space application. Background technique [0002] Due to the limitation of the effective launch load and launch volume of the launch vehicle, the requirements for the carried payload are to have a small weight and a small launch volume. Large-scale space structures are in a folded state during launch, and after being launched into orbit, they form the state required by their design by unfolding to achieve their design functions. Most of the existing unfolding structures are unfolded mechanically. Such unfolding structures not only have high weight, but also have low folding efficiency. In addition, in order to meet the requirements of deep space exploration, traditional structural methods are powerless for ultra-long deep space exploration structural components. SUMMARY OF THE INVENTION [0003] In order to solve the problems of high weight, low folding efficiency and inability to build a l...
