FIELD: aviation.
SUBSTANCE: for the control of dynamic balancing, metrological examination is carried out to estimate the validity of signals from sensors and measurement systems, anomalous emissions in the measurement sequence are rejected, training measurement arrays are accumulated first for the helicopter hover condition without turning in the horizontal plane. Then in various modes and at various speeds of horizontal flight and then in all controlled flight modes, individual tolerance limits of dynamic symmetry parameters are formed, the current dynamic symmetry parameters are measured and compared with the tolerance limits. The control is carried out online on board the helicopter and on ground registered data processing device, after the flight, taking into account the results of the previous operation.
EFFECT: regular reliable control of the balance of the main and steering helicopter rotors and their blades is ensured.
