Abstract

Mathematical models of 3D transient temperature fields in angular velocity measurement unit (AVMU) and constituent fiber-optic gyros both in basic structure and in the structure with reversible heat control system (HCS) are developed and implemented. Comparative analysis of temperature fields under complex temperature effects is conducted. Efficiency of reversible double-circuit HCS application is assessed.
