Method for electrode of satellite-borne electrostatic forming membrane reflector unfolding antenna

Abstract

The invention belongs to the technical field of radar antennas, and particularly discloses a method for an electrode of a satellite-borne electrostatic forming membrane reflector unfolding antenna. According to the method, the characteristics of systematic manufacturing and installing of the electrode are sufficiently considered, and clipping and lofting are carried out on a flexible cable and the membrane electrode in a separated mode. Due to the fact that tension of the flexible cable is easily measured, it is emphasized that flexible cable clipping is carried out in the tensioning state, and the flexible cable clipping accuracy is controlled. The hook face unfolding and stress releasing principle can not be easily used when tension of a membrane is measured, the membrane is clipped in the plane stress-free state, and the manufacturing clipping accuracy of the membrane can be effectively controlled. Then the flexible cable is connected with the membrane electrode through a positioning template in the tensioning state, and the installation accuracy of the electrode can be effectively controlled. The method is reliable in principle and easy and convenient to operate, and the method for effectively controlling manufacturing and installing of the high-voltage electrode of the electrostatic forming membrane reflector unfolding antenna is provided.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to a method for deployable antenna electrodes on a space-borne electrostatically formed film reflective surface, which is used to control the electrode manufacturing and installation accuracy of the spaceborne electrostatically formed film reflective surface antenna. Background technique [0002] With the rapid development of aerospace science and technology activities, higher and higher requirements are put forward for spaceborne deployable antennas, which are manifested in two aspects of large aperture and high precision. For example, NASA's next-generation spaceborne weather radar requires a caliber of 35m and a frequency of up to 35GHz (the antenna's on-orbit surface accuracy is required to reach 0.17mm). In the future, communication, ground remote sensing and other fields also have potential demands for large-aperture, high-precision spaceborne antennas. However, the re...
