Abstract:
The computer model of the thermal vacuum system (thermostat) is proposed to regulate a temperature of a primary mirror of the cooled optical collimator, being used for testing of optoelectronic space equipment operating at an infrared spectral range. A novel numerical method allowing solving the system of nonlinear equations of radiative heat transfer is developed, complying with a temperature control over the primary mirror surface.
Keywords:
thermostat, collimator, radiative heat transfer, heat balance, thermal aberration of a mirror.
