Considering dynamics of the gyroscopic device ring resonators actually means only analyzing the problem of oscillations in a plane. However, experimental data show that the resonator oscillations often go out of the resonator plane. For example, it happens due to a loss in stability from the temperature deformations. In addition, a flat model is not making it possible to describe oscillations of the resonators with spatial defects. In this regard, it is of interest to form an adequate dynamic model of the ring resonators in a spatial setting. For this purpose, this paper proposes to apply the three-dimensional tensor equations of the curvilinear flexible elastic rod mechanics to describe the ring resonator oscillations. It uses an example of the wave gyroscope real design to analyze a completely new type of the resonator shape defect called the screw defect.
