FIELD: physics. ^ SUBSTANCE: antenna dome has a ceramic cladding, a metal attachment ring and a heat-insulating layer in between, which is formed by at least two sections made from heat-resistant fibre-glass, and joined by a heat-resistant adhesive with the cladding and the attachment ring. In the zone of joining with the heat-insulating layer, the ceramic cladding has on its inner surface an annular cavity and the sector on the outer surface has a reciprocal annular protrusion. The sector of the heat-insulating layer is made from heat-resistant fibre-glass based on polyimide, aluminium-chromium-phosphate or phenol-formaldehyde binder. ^ EFFECT: operating capacity of the antenna dome in high heat and force load conditions, including beyond operating range of the heat-resistant adhesive. ^ 4 cl, 1 dwg |
