Aerospace Instrument-Making Annotation << Back Modeling of thermal control system a precision angular rate measurement gyrodevice Bordachev D.A., Podchezertsev V.P., Fateev V.V. The article is devoted to development and modelling of thermal control system a precision angular rate measurement gyrodevice for space purposes. The method of the analysis thermal control system on the basis of synthesis of calculations of a re-al design with the distributed thermal characteristics in program ANSYS with meth-ods of formation and calculation of adequate discrete analytical thermal model in program Simulink (Matlab). The technique of construction of thermal model of two contours thermal control system in program Simulink is shown. Purpose of the first contour is to maintain temperature of space around of the case of a sensitive ele-ment of the device, and the second contour is to stabilize thermally directly the sen-sor device case. The results of the thermal control system modeling at various tem-perature influences on the device are given. Keywords: gyroscope, two contours thermal control system, thermal model.
