Abstract

The invention provides an inflation expansion truss solar panel array capable of on-orbit assembly. The invention relates to an inflation expansion truss solar panel array to solve a problem that a present solar panel can not satisfy a large area solar panel requirement of spacecrafts such as a satellite, a space station and the like. Technical schemes of the invention are as follows: firstly, along a vertical equal interval, an assembly inflation expansion vertical truss is provided with a plurality of assembly inflation expansion solar panel units which are in mortise-tenon connection with truss unit connection columns of an assembly inflation expansion truss unit through framework unit connection columns; secondly, along a vertical direction, the assembly inflation expansion vertical truss is provided with a plurality of the assembly inflation expansion solar panel units; thirdly, one end of an assembly inflation expansion transverse truss is aligned with one end of the assembly inflation expansion vertical truss, and is in mortise-tenon connection with the truss unit connection columns through the framework unit connection columns. The inflation expansion truss solar panel array is applied to an astronaut on-orbit assembly inflation expansion truss solar panel array.

Description

technical field [0001] The invention relates to an inflatable and unfolded truss type solar panel array. Background technique [0002] With the development of space station technology, satellites, space stations and other spacecraft need to have a greater power supply, which requires a larger area of ​​solar panels. [0003] Existing solar panels mainly adopt the structural form of mechanically unfolded solar panels. The mechanical unfolding support structure is composed of many rigid components connected by a connecting mechanism, a control unfolding mechanism, and a locking mechanism. In use, there are complex structures, easy failures, poor deployment reliability, heavy overall weight, low folding efficiency, and launch volume. Large and other problems; due to the increase in the structural size of the sail panel, its launch volume has increased significantly, making it difficult or even impossible to launch spacecraft such as satellites or space stations; due to the lar...
