Single rod type main bearing structure applicable to micro-nano remote sensing camera

Abstract

The invention discloses a single rod type main bearing structure applicable to a micro-nano remote sensing camera, relates to the technical field of space optical remote sensing, and solves the problems that the existing coaxial space camera main support structure is high in weight and large in shading ratio and process difficulty, an integrated formation structure is too high in production cost and long in processing period and the like. According to the single rod type main bearing structure applicable to the micro-nano remote sensing camera disclosed by the invention, a secondary mirror bracket and a support rod are in flanged connection; the support rod and a main backplate are in flanged connection; due to adoption of a split type structure, instead of an integrated structure, the processing difficulty of silicon carbide can be greatly reduced; the production period and the manufacturing cost are greatly reduced; the low-cost and short-period requirements of micro-nano load are satisfied; a countersunk bottom hole and an embedded part are pre-punched on a silicon carbide material; an epoxy resin adhering manner is adopted; and the problems that the process of directly processing a threaded hole in the silicon carbide material is high and damage is easily caused can be avoided. By means of the single rod type main bearing structure applicable to the micro-nano remote sensing camera disclosed by the invention, the structural precision and the stability are improved; the structural part number and the manufacturing process are simplified; and the processing period and theprocessing cost are shortened.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensing, in particular to a single-rod main load-bearing structure suitable for micro-nano remote sensing cameras. Background technique [0002] Remote sensing applications in the new era put forward more stringent requirements for image data: high spatial / temporal resolution, high-precision image positioning, etc. Traditional single satellites cannot complete the above tasks. Micro-nano satellites have the characteristics of light weight and compactness, low development cost, short production cycle, and diversified launch forms. They are an important way to solve the above needs and become the most active research direction in the aerospace field. [0003] The ultra-light feature of the micro-nano satellite camera requires its main support structure to be light in weight, high in rigidity and good in stability. Traditional coaxial space cameras mostly use a load-bearing cylinder or ...
