Bionic dry adhesion system for capturing non-cooperative targets in in-orbit manner

Abstract

The invention discloses a bionic dry adhesion system for capturing non-cooperative targets in an in-orbit manner. The bionic dry adhesion system comprises a fuselage, flexible driving mechanisms, bionic paw mechanisms and bionic foot sole mechanisms. The flexible driving mechanisms and the bionic paw mechanisms are arranged on the fuselage, the bionic foot sole mechanisms are movably connected with the bionic paw mechanisms, adhesion units made of bionic adhesion materials are arranged at the tail ends of the bionic foot sole mechanisms, the bionic foot sole mechanisms can be driven by the flexible driving mechanisms to laterally move relative to the bionic paw mechanisms, and the bionic paw mechanisms can be driven by the flexible driving mechanisms to carry out adduction movement, so that the bionic adhesion units can tangentially move under the effect of normal pre-pressures to generate adhesion force. The bionic dry adhesion system has the advantages that the non-cooperative targets in spaces can be repeatedly adhered by the bionic dry adhesion system, and accordingly effects of capturing the non-cooperative targets can be improved.

Description

technical field [0001] The invention relates to the technical field of on-orbit capture of non-cooperative targets, in particular to a bionic dry adhesion system for on-orbit capture of non-cooperative targets. Background technique [0002] The powerful kinetic energy of non-cooperative targets in space poses a serious threat to spacecraft in orbit. According to statistics, non-cooperative targets have caused many cases of spacecraft damage and catastrophic failure. With the development of aerospace industry, the number of such cases is still growing rapidly. The capture technology of non-cooperative targets has become a research hotspot in the aerospace field. [0003] At present, the more successful non-cooperative target acquisition technology is to use ejection flying net to capture. For example, Chinese patent CN102991731A discloses a flying net ejection acquisition device for the capture of abandoned spacecraft. The flying net is unfolded, and after forming an envelo...

Problems solved by technology

However, due to the use of pyrotechnics, the flying net is a one-time use capture device, and the application cost is relatively high when the number of non-cooperative targets is increasing year by year
