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

FIELD: missiles.

SUBSTANCE: invention relates to design of structures of antenna fairings of high-speed rockets with shells from heat-resistant ceramic materials. Antenna cowl includes a ceramic shell and a metal butt joint, interconnected by heat-resistant adhesive. Optimum thickness of the frame is defined proceeding from the equality of bending stiffnesses of the inner flange of the frame and the shell in their middle cross-section. Radial thermal gap between the shell and the frame is selected structurally, taking into account the maximum radial expansion of the frame and the plastic properties of the heat-resistant adhesive. End gap between the shell and the frame is accepted proceeding from the condition of joint tightness provision, but not more than radial gap.

EFFECT: technical result consists in the possibility of ensuring the operability of the antenna fairing for conditions of high-speed heating at the initial section of the trajectory and high aerodynamic heat-power action at the cruise trajectory with the prevailing heat load.
