Abstract. Prospects of applying ion-plasma and beam technologies (IPBT) to the production of cardan-less electrostatic gyro rotor with the high geometric accuracy and complex of functional parameters are considered. Technical solutions to the problem of formation of the moment of inertia of the spherical rotor and adjusting its imbalance by spraying the coating on the rotor surface with variable thickness and by local laser evaporation of point mass are proposed. Mathematical models for the management of the main rotor’s functional parameters based on the use of IPBT are presented. The results of the practical application of the developed models are demonstrated.
Keywords: ion-plasma technologies, laser marking, vacuum deposition, gyroscopes
