METHOD OF BALANCING HELICOPTER AXIAL ROTORS

摘要

FIELD: aeronautical engineering. SUBSTANCE: method consists in measuring the magnitude and phase of vibrations of helicopter fuselage in hover mode at initial state at successive measurements of vibrations and their increments due to test unbalances set separately for upper and lower rotors followed by calculations of unbalances for each rotor. EFFECT: enhanced reliability. 2 cl, 2 dwg
