Winding type inflatable telescopic arm capable of working in large range and long distance

Abstract

The invention discloses a winding type inflatable telescopic arm capable of working in a large range and a long distance, and belongs to the technical field of space deployable structures. The invention provides a winding type inflatable telescopic arm capable of working in a large range and a long distance in order to meet the use requirements of an existing space telescopic arm, and particularly consider the requirements of the launching volume, the launching mass, the action space range, the operation difficulty and the like of the space telescopic arm. One end of the inflation arm is wound on the folding and unfolding device, the folding and unfolding device achieves winding folding and inflation unfolding of the inflation arm, the other end of the inflation arm is used for being connected with execution mechanisms at the tail ends of different core cabins through the expansion end to complete various space tasks, and an inflation system and an air exhaust system are installed in the folding and unfolding device. The controllable telescopic space inflatable telescopic arm is achieved, the control mode is simple and reliable, the inflatable wall is folded in a winding mode, the folding mode is compact, the size is small, the weight is light, the launching size and difficulty are remarkably reduced, and the launching cost is low.

Description

technical field [0001] The invention belongs to the technical field of space expandable structures, and in particular relates to a coiled inflatable telescopic arm capable of large-scale and long-distance operations. Background technique [0002] The space extension arm is the infrastructure for completing tasks such as space assembly, space maintenance, and emergency space rescue, and it is also an indispensable and important mechanism for assisting astronauts to get out of the cabin. When the space extension arm is carried and launched, the launch mass is required to be small and the folding volume is small, while the in-orbit deployment requires high rigidity and high stability. [0003] At present, the structural forms of the extension arm mainly include mechanical type and inflatable type. The mechanical extension arm has problems such as large mass, low folding efficiency, high launching cost, and limited range of action space. In addition, the astronauts mainly use t...

AI Technical Summary

Problems solved by technology

[0003] At present, the structural forms of the extension arm mainly include mechanical type and inflatable type. The mechanical extension arm has problems such as large mass, low folding efficiency, high launch cost, and limited range of action space.

In addition, the astronauts mainly use the robotic arm for auxiliary operations after leaving the cabin. The robotic arm system is complex and huge. Once the equipment fails, it will be very dangerous, which increases the difficulty for the astronauts to operate outside the cabin.

The inflatable extension arm has the advantages of light weight and large folding ratio, but there are still some deficiencies, such as the difficulty of realizing multi-degree-of-freedom rotation operations, low rigidity of inflatable deployment, and insufficient stability of extension and contraction
