Temperature stabilization of the angular velocity measuring device

Abstract

The article examines the possibility of using an active two-circuit thermal control system to reduce the influence of temperature disturbances on the components of the angular velocity measuring device. Special attention is devoted to the problem of temperature stabilization in fiber-optic gyroscopes mounted in the measuring device. The study of the inhomogeneous nonstationary temperature field of the angular velocity measuring device with a two-circuit reversible thermal control system on Peltier thermal batteries is carried out. Thermal and mathematical models of the considered dynamical system are constructed. Specialized software for numerical simulation has been developed, which allows calculating and visualizing real-time inhomogeneous, three-dimensional, non-stationary temperature fields of the device under conditions of complex non-stationary thermal effects of internal and external sources. It is shown that the use of a two-circuit reversible thermal control system can help to significantly reduce the influence of external non-stationary temperature disturbances on the temperature stability of fiber-optic gyroscopes in various operating conditions, such as vacuum and weightlessness. The energy consumption and the increase in the weight and size characteristics of the device are estimated.
