Rigidizable inflatable capturing hand

Abstract

The invention discloses a rigidizable inflatable capturing hand, and belongs to the technical field of spaceflight on-orbit control. The invention discloses the rigidizable inflatable capturing hand which comprises a plurality of inflatable knuckles, a plurality of inflatable joints and a plurality of hooping air bags, wherein the inflatable knuckles are sequentially arranged, the inner ends of the adjacent end faces of every two adjacent inflatable knuckles are connected through a hinge, one inflatable joint is fixedly connected between every two adjacent inflatable knuckles, the inner sides of the outer surfaces of the inflatable knuckles are connected to the hooping air bags, and the inflatable knuckles are rigidizable inflatable knuckles. According to the rigidizable inflatable capturing hand, winding type capturing of the capturing hand is achieved through inflation and deflation of the driving air bags in the inflatable joints, the capturing force can be controlled and adjusted, the control mode is simple, reliable and easy to achieve, the rigidizable inflatable capturing hand has high adaptability to targets of different shapes and sizes, the rigidizable inflatable capturing hand is used for operations such as on-orbit capturing, releasing and relative fixing of the space target.

Description

technical field [0001] The invention belongs to the technical field of aerospace on-orbit control, and in particular relates to a rigidizable inflatable catcher. Background technique [0002] On-orbit operation and service of space targets (including cooperative targets and non-cooperative targets) requires capture, release, and relative fixation of targets by capture agencies. The existing space target capture mechanism is mainly in the form of rigid mechanical arm or mechanical claw, which can be used to capture space cooperation targets. However, for non-cooperative targets, including self-owned aircraft without cooperative grasping mechanisms, invalid satellites, and other large-scale space debris, it is necessary to use large-scale capture mechanisms to complete the task. For mechanical capture mechanisms, it is It is necessary to greatly increase the size of the capture mechanism and increase the number of joints, which will increase the launch volume and mass of the ...

Problems solved by technology

However, for non-cooperative targets, including self-owned aircraft without cooperative grasping mechanisms, invalid satellites, and other large-scale space debris, it is necessary to use large-scale capture mechanisms to complete the task. For mechanical capture mechanisms, it is It is necessary to greatly increase the size of the capture mechanism and increase the number of joints, which will increase the launch volume and mass of the capture mechanism and its control system, significantly increase the complexity and operational difficulty of the system, and reduce the operational reliability of the system. Increased manufacturing and launch costs

In addition, during the capture process, the rigid manipulator or capture hand has a small capture area, which can easily lead to excessive local capture force, resulting in damage to the capture mechanism and the captured target.
