Abstract

Generic procedure of thermal-balance and thermal-vacuum test operations under the ground test program was considered. The minimum requirements for functional tests were determined. The modes of testing were proposed, the requirements for the materials of the spacecraft and electronic devices were described. The sequence of air conditioning of devices was determined. The technique of thermal-vacuum tests was offered. It involves two stages: functionality test of devices and spacecraft and their degasification. The degasification operation of devices was developed in detail. The rational modes of its carrying out are defined. It is shown that this technique can significantly reduce the pumping time of the vacuum chamber and sharply reduce the rate of evolution of high-molecular compounds. It is established that the selected modes of degasification operations of devices can improve the quality and reliability of the spacecraft as a whole.
