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

FIELD: antenna equipment.

SUBSTANCE: invention relates to design of structures of antenna domes of high-speed rockets with shells from heat-resistant ceramic materials. Antenna dome includes a ceramic shell, a metal frame and an annular shell arranged coaxially between them, interconnected by a heat-resistant adhesive. Circular shell ring is made from laminated composite material and has thickness equal to no more than 0.5 of shell wall thickness in radioparent zone and interlayer strength exceeding, at least, by 20 % strength of adhesion layer. Thickness and height of annular shell in area from front end of frame to radio-transparent zone of shell are determined by calculation, based on the condition of providing minimum tensile stresses in the shell with smooth reduction of the thickness of the shell wall from the front end of the frame to the radiotransparent zone to a level which limits the allowable reduction of the given radio characteristics.

EFFECT: high carrying capacity of the ceramic shell and the joint assembly under conditions of considerable power action on the dome structure.
