It is built the refined model of the elastic interaction of penetrating acoustic radiation with float gyroscope to detect non-linear effects of resonant type in the suspension at the operational use of the gyroscope.
It is investigated the cylindrical shell part of device case, computational model of which is built in the form of elastic compliance shell with acoustic impedance.
The regularity of elastic radial displacements of the material of device body in the radial direction is determined and its acoustic permeability in a hypersonic flight is defined. The conditions for the appearance of "acoustic transparency" of the case in the event of resonance overlap are outlined.
An application area in suborbital and atmospheric hypersonic technology at forming initiation of the resonance overlap in the suspension of gyroscope, leading to the onset of the "acoustic transparency" of the body.
The obtained results can serve as the basis of decision-making in the selection of design models of investigated effects from the perspective of pending outline of wave size in hypersonic flight operating conditions and ensuring the appropriate choice of impedance of the body material.
