FIELD: physics.
SUBSTANCE: invention may be used in systems intended for overcoming rotor system resonance. For this, signal proportional to rotor angular rotation speed fed to processor is processed, wherein said signal is transformed in characteristic of acceleration. Note here that said characteristic is differentiated two times for first zerofilling of third derivative to be used to determine resonance start zone.
EFFECT: on-line indication to overcome resonance.
