Abstract. Technological methods used for formation of the functional parameters, like moment of inertia and imbalance of cryogenic gyroscope rotor, are considered. As the material of the rotor, it was proposed to use a carbon-metal nanocomposite well combined in physical and chemical properties with niobium, but demonstrating a strong anisotropy of properties, which brings to the appearance of an imbalance. The performed research was aimed at revealing technical solutions for formation of moments of inertia and correction of imbalance caused by the anisotropy of the rotor substrate material. The proposed complex is a qualitatively new technological methods and means of manufacture of the rotor of a cryogenic gyroscope associated with the coordinated operations of the formation of the rotor workpiece of pyroboroncarbon and application of superconducting niobium coating. The developed technology was patented and used for the manufacture of an experimental rotor of a cryogenic gyroscope.
Keywords: anisotropic material, niobium, rotor, cryogenic gyroscope, imbalance
