Abstract
The emergence of hypersonic technology pose a new challenge for inertial navigation sensors, widely used in aerospace industry. The main problems are: extremely high temperatures, vibration of the fuselage, penetrating acoustic radiation and shock N-waves. The nature of the additional errors of the gyroscopic inertial sensor with hydrostatic suspension components under operating conditions generated by forced precession of the movable part of the suspension due to diffraction phenomena in acoustic fields is explained. The cause of the disturbing moments in the form of the Coriolis inertia forces during the transition of the suspension surface into the category of impedance is revealed. The boundaries of occurrence of the features on the resonance wave match are described. The values of the “false” angular velocity as a result of the elastic-stress state of suspension in the acoustic fields are determined.

Summary
This paper is related to the field of applied mechanics and devoted to the study of polyaggregate inertial sensors under the operating conditions of hypersonic motion [1]. The Peoples Republic of China tested a hypersonic glider called WU-14 It is a controlled device, which is mounted on the aerodynamic payload fairing of a ballistic missile. China became the third nation, after the United States and Russia, to possess hypersonic technology The benefits of such technology are due to the long shooting range (up to a global attack on any part of the Earth’s surface), a fairly simple device unit (no boosters are needed), a large warhead mass and high speed of the flight—more than 10 Mach. The advantage of hypersonic missiles lies in a lower cost, and greater flexibility in application technology than gliders launched by ballistic missiles Both types of hypersonic weapons can carry a conventional or nuclear warhead. The most complicated inertial sensor suspension—the polyaggregate one—is under consideration
