In this paper, the perspectives of using the features of acoustic wave propagation to design rotation rate sensors (RRS) are discussed. The possibility of developing the solid-state sensitive elements (SE) of RRS on acoustic waves of circular polarization is shown. The theoretical basis of bulk acoustic wave propagation under rotation is given. The direct excitation of circularly polarized acoustic wave (CPAW) is considered, the design of the CPAW emitting transducer is offered. The results of experimental studies that indicated the circular nature of the particle motions in the radiated wave are discussed. The principally new concept of the RRS SE design on CPAW, being able to operate under high vibration and acceleration, is proposed. The experimental results revealed a high correlation with theoretical and numerical predictions and confirmed RRS on CPAW operability.

The article presents the review of materials of the international scientific conference “Economic system of modern Russia: ways and development goals”. During the conference there was extensive discussion about the economic system of modern Russia, the revival and development of the real sector of the economy based on new technologies, the transformation of a rent-based economy in the innovation economy by re-industrialization, the problem of economic security of Russia in the conditions of external and internal threats. Identified and justified the need for a substantial increase in regulatory activity of the state in modern conditions.
