Abstract

The subject of research is the industrial sample of the inertial sensor in the form of a two-axis gyroscope with liquid and static suspension.

The possibility of reducing the acoustic error under hypersonic motion is analyzed using the methods of design and technological solutions.

The purpose of the paper is comparative analysis of the bench and seminatural tests of differentiating gyroscope with the analytical assessment of the measurement error under the influence of N-wave at zero and finite Gaussian curvature of the float suspension.

The effect of the acoustic float impedance increasing by the change in the meridian suspension line geometry was used as the method of passive sound insulation of inertial sensor from the effects of penetrating acoustic emission.

Comparative analysis of the bench instrument acoustic error and analytically detected non-zero Gaussian curvature for suspension gives grounds for decision-making on reduction of the gyroscope systematic inaccuracy under hypersonic motion.

The results may be used in the inertial positioning means design and external target designation.

The proposed method outlines a number of issues for practical providing of acoustic comfort of the onboard equipment using the passive methods
