METHOD OF DYNAMIC TESTS OF MEMBERS Russian patent published in 1995 - IPC

Abstract RU 2034256 C1

FIELD: aeronautical engineering. SUBSTANCE: during tests variable force is applied to the member under test, displacements are measured, and oscillation frequency is determined, variable force Q is applied at distance l to the axis of main-rotor shaft 2 and in parallel with the axis of shaft 2. EFFECT: determination of tone of shaft natural oscillations with angular oscillations of main-rotor hub. 1 dwg
