DOI 10.3103/s1052618823010119
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
