• Synergistic effects in two types of “solar reflectors” thermal control coatings under conditions simulating geostationary orbit have been investigated by exposing them to separate and complex (simultaneous and continuous) irradiation by solar spectrum photons, electrons and protons. Energy and flux of protons and electrons were selected using a replacement model. This model based on replacement spectra of charged particles by monoenergetic beams during ground testing using the experimental fluence and energy dependences of the changes in solar absorptance. It has been found that the change in solar absorptance of complex irradiation is less than the sum of changes in solar absorptance due to the separate irradiation. Also, the additivity coefficient reaches up to 0.55 and depends on the type of coatings, acceleration and time of complex irradiation.
