FAIRING Russian patent published in 2021 - IPC H01Q1/42 

FIELD: aircraft and rocket equipment.

SUBSTANCE: invention relates to the field of aircraft and rocket equipment and can be mainly used in the manufacture of antenna fairings, mainly high-speed surface-to-air missiles. Disclosed is an antenna dome for high-speed missiles, comprising a ceramic shell, connected by an inner surface with an elastic adhesive with a metal adapter. Butt annular element is rigidly connected to adapter end face. Outer surface of abutting annular element is flush with outer surface of shell at its end, and inner is flush with inner surface of adapter or projects relative to it inside shell at design value. Length of the adhesive joint is commensurate with the design action at the maximum force action on the fairing or exceeds the design one by 1.5-2.0 times. Between end faces of shell and butt element there introduced is equal-thickness remote layer from elastic adhesive or elastic adhesive with fibrous filler with thickness commensurable or exceeding average value of optimum range of thickness of adhesive strength layer of adhesive. Rigidity for radial reduction of adapter is 0.5-2.0 of radial rigidity of shell area adjacent to adapter. Thickness of the remote layer of the adhesive is commensurate with or exceeds 1.5 times the average value of the optimum thickness range of the adhesive strength layer of the adhesive in terms of strength and manufacturability of the fairing. Middle part of the adapter is made solid or with longitudinal through slots; at that, thickness of its nose part is commensurable or exceeds or reduced in comparison with the middle part.

EFFECT: technical result consists in improvement of temperature and power operational parameters of rocket fairings; this invention allows simplifying the technology of creation of rocket fairing and ensuring creation of reliable structures operable at short and long operating modes of modern missiles.
