ANTENNA FAIRING Russian patent published in 2020 - IPC H01Q1/42 B64C1/36 

FIELD: aircraft and rocket equipment.

SUBSTANCE: invention relates to the field of aircraft and rocket equipment and can be used mainly in designs of radiotransparent antenna fairings, which are a hoard from aerodynamic action of antenna devices of homing heads (AD HH). Essence of the declared solution consists in the fact that the antenna fairing comprises a ceramic shell and a dome-shaped radiotransparent heat-shielding screen located inside the shell, on surface of which there applied is heat-resistant radiotransparent coating with thickness in range of 0.01–5 mm, made in form of heat-resistant material with transparency area in the wavelength range of 1–7 mcm or wider, containing uniformly distributed in the volume with volume fraction in range of 10–90 % in the form of pores, having average size in range of 0.5–20 mcm, and effectively reflecting thermal radiation of the shell in the wavelength range of 1–7 mcm or wider.

EFFECT: technical result of the invention is reduction of thermal impact on the AD HH in conditions of non-stationary aerodynamic heating with provision of high radio engineering characteristics in a wide frequency range.
