Abstract

The invention provides a compact type inertia wheel for spacecraft. The compact type inertia wheel is characterized by comprising a main inertial part, an outer connecting part and a connecting part;the main inertial part is connected with the outer connecting part through the connecting part; themain inertial part, the outer connecting part and the connecting part are arranged in a concentric ring shape; weight reducing holes are uniformly formed in the circumference of the connecting part; and a stop opening and a thread are formed in the outer connecting part. The compact type inertia wheel has small outside diameterand large inertia, and the miniaturization use requirement of spaceflight is met; rhenium is adopted for manufacturing, and the inertia is improved by increasing density; the stop opening is additionally designed at the thread position to improve the centering performance; the weight reducing holes are formed to remove useless weight; rhenium has the characteristics ofcorrosion resistance and high and low temperature resistance, and is suitable for space environment; and a mother material is a rhenium cake formed by high temperature and high pressure, and good machining property is achieved.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a compact inertia wheel for spacecraft. Background technique [0002] At present, various mechanical products used in space technology are limited by the size of spacecraft. The inertial devices suitable for the ground environment are mostly stainless steel products, which are too heavy and bulky to be suitable for the aerospace field. Therefore it is very necessary to develop a small-sized high-inertia product suitable for aerospace products. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a compact inertia wheel for spacecraft. [0004] A compact inertia wheel for spaceflight provided according to the present invention, including main inertial parts, external parts, and connecting parts; [0005] The main inertial parts and external parts are connected through connecting parts; [0006] The main inertial par...
