Abstract

The article examines the impact of modern structural materials' characteristics on the advancement of the aerospace and rocket industries. The growing role of ceramic materials with unique properties is emphasized: heat resistance, high hardness and strength; resistance to oxidation and corrosion; radio transparency; lower density compared to metals. It is often the case that they are indispensable in the manufacture of elements of rocket systems and defense industry products. However, technical ceramics belong to the category of difficult-to-machine materials, which complicates the processes of manufacturing critical products from them. Possible ways to improve the efficiency of manufacturing rocket antenna fairing - thin-walled shells of complex geometric shapes made of sitalls (a type of glass ceramics) are considered. Options for improving traditional technological processes for the manufacture of fairings using CNC machines for their mechanical processing are proposed. The use of additive SLS technology in the production of antenna fairings is substantiated. A variant of an improved technological process for manufacturing antenna fairings was presented.
