Abstract

Mathematical modeling of heat processes of miniature onboard equipment (МОЕ) for operation in nonpressurized modules is discussed. It is formulated and solved the problem of criteria conditions determination providing the temperature field of МОЕ operating in a spacecraft identical to the temperature field of the same МОЕ operating in climatic chamber under equal heat generation of the instruments. It allows us to change the expensive thermal tests for МОЕ in heat vacuum-chamber by much more cheaper thermal tests in climatic chamber.
