AN ACTIVE THERMAL CONTROL SYSTEM ON PELTIER MODULES FOR A STRAPDOWNIMU BASED ON FOG FOR SPACE AND GROUND APPLICATIONS

摘要

An active two-circuit thermal control system based on Peltier modules is proposed as a means of significant (up to 100 times) increase in precision of strapdown rate measuring devices with fiber optic gyroscopes. Mathematical models of thermal processes in dynamic systems of rate measuring devices and gyroscopes of the thermal control system which took into account correlation between internal and external flows of the system have been developed and studied. Qualitative and quantitative assessment of such dynamic system operation under complex heat effects both in normal and gravity-free space environment with reduced atmospheric pressure has been done.
