FIELD: physics, radio. ^ SUBSTANCE: radiolucent thermoregulating coating (RTRC) is intended mostly for thermal regulation and electrostatic protection in the form of screens or in the form of coating adhered to surface of spacecraft design elements. Coating contains external electroconductive light-reflecting layer and substrate from polymer material that are transparent for electromagnet radiation of wide frequency range, between which additional electroconductive layer is installed, being transparent for electromagnet radiation of wide range of radio frequencies and made from semi-conductor. On substrate rear side the second electroconductive light-reflecting layer is applied, with larger thickness. All layers are made from radiation-resistant materials that do not reflect thermal radiation. Thickness of light-reflecting layers lies within the range from 4x10-8 to 20x10-8 m. Light and easy-to-manufacture coating reflects at least 50% and transmits not more than 5% of solar radiation, which does not reflect thermal radiation and transmits more than 99% of electromagnet radiation in range of frequencies from several megahertz to dozens of gigahertz. ^ EFFECT: creation of coating that is simple and easy-to-manufacture for thermal stabilisation and reliable electrostatic protection of antenna systems. ^ 3 cl, 1 dwg |
