Abstract: The features of the acoustic impact on aircraft aggregates made of polymer composite materials are investigated. A technique for setting the wave angle is described; it equalizes the scale factors of both measuring channels of the differential aggregate made of polymer composite materials and compensates for the cross-damping error. Analytical expressions are obtained for the scale factor and the zero offset of the differential aggregate made of polymer composite materials. This scale factor, in contrast to the discrete noise oscillation mode, does not depend on the resonant oscillation amplitude and frequency. The operating mode of the aggregate made of polymer composite materials is shown to have an ability to compensate for the resonator frequency difference, when measuring the angular velocity, by means of the control system.
