Abroad spectrum of materials is considered, developed and used within ONPP Tekhnologiya for manufacturing radioparent domes for different types of aircraft. Theoretical and experimental development is carried out in the enterprise, and optimum structures are determined for the walls of antenna domes made from different composite materials taking account of a set of operational effects in aircraft, providing creation of broadband radiolocation systems with improved structural strength by not less than 10%; optimum production methods and a scheme for manufacturing complexly shaped domes are provided, including those based on multilayer structures of heat-resistant radioparent composite materials. © 2015 Springer Science+Business Media New York

Dependence of the effect of highly efficient milling on preparation of dense solid electrolytes in the form of films of chemically deposited zirconium dioxide powder is studied on the example of the system ZrO2 + 8 mol.% Y2O3. Changes in ZrO2 particle morphology and composition occurring during milling affect sintered ceramic properties. During sintering there is inheritance of the powder structure. A reduction in the degree of agglomeration during milling of chemically precipitated powders in a bead mill (to 2 μm) makes it possible to obtain a more compact nanostructure (to 50 nm) during sintering compared with the structure of specimens from powders after milling in a ball mill. Optimum properties are determined for starting powders in order to prepare high quality dense films up to 170 μm thick by pouring on to a moving substrate. © 2015 Springer Science+Business Media New York
