“…The most susceptible to the flying vehicle’s angular motion are the elastic displacements of the gimbal’s surface in the plane of frame [ 8 ]. The hypothesis has logic justification and explores considerable (approximately by two orders) exceedance of the amplitude of elastic displacements in this direction in comparison with two others [ 9 ]. The gimbal’s elastic stress interacts with all three constituents of the vehicle’s angular motion and serves for the occurrence of disturbing factors acting on the gimbal’s output axis ( Figure 1 ).…”

The response of the float two-stage angular velocity sensor to the simultaneous perturbation from the rocket body—kinematic perturbation—and the penetrating acoustic radiation from the propulsion engines of the launch vehicle were determined. The solution of two equations was successively analyzed: the first and second approximations, and the synchronous and asynchronous fuselage pitch. The reaction of the float gyroscope to harmonic oscillations of the base was analyzed. The effect of the zero shift of the device due only to the angular oscillations of the launch vehicle body and the penetrating acoustic radiation was considered. The presented results reveal the nature of the appearance of inertia forces acting on the impedance surface of the gyroscope float suspension. Acoustic radiation that passes into a device generates many vibration modes on the surface and can have a considerable effect on the precision of float two-stage angular velocity sensor and gyro-stabilized platforms.

“…The aforementioned suggest the idea that, for acoustic fields, the existing calculated models of gyroscopes’ inaccuracies require critical and comprehensive reinterpretation [ 9 ]. First of all, the gimbal should be considered as a system with distributed parameters or discrete-continuous parameters.…”
