Abstract

Technological solutions based onthe integrated approach are presented, which optimize the manufacturing process and satisfy the requirements imposed on spherical rotors of electrostatic gyros. System modelingis used to study the main stages of defining the rotor functional parameters and to constructa system of models that determines the coordinated processes of diffusion welding, precision sphere lapping and rotor weight correction. The practical results of rotor manufacturing and the prospects for accuracy enhancing are provided.

Highlights

To improve a gyro with electrostatically suspended rotor (ESG), a group of problems should be solved, the most important being meeting more stringent requirements for the spherical rotor parameters [1,2]
To increase the efficiency of this weight correction process, a model was developed based on laser evaporation of local point mass at the final stage of rotor manufacturing [19, 20], which determines two stages of the process:
Based on an integrated approach, a system of models has been developed that determines the main stages of the manufacturing process and the scientifically grounded set of coordinated technical solutions to define the functional parameters of ESG rotors

Summary

Introduction

To improve a gyro with electrostatically suspended rotor (ESG), a group of problems should be solved, the most important being meeting more stringent requirements for the spherical rotor parameters [1,2]. The quality of the rotor spherical surface corresponds to the 13throughness class, which meets the requirements for metal optics Satisfying such stringent requirements is an extremely difficult technical task, special attention is given to the technological aspects of ESG spherical rotor manufacturing.
