WebJan 6, 2024 · If the Rotor RPM (N R) is low, the corrective action to stop ground resonance is to shutdown the engines immediately and fully lower the thrust to place the blades in low pitch. Shutting down the engines reduces the N R , hence the lift of the blades. The aft rotor head is equipped with centrifugal droop stops which provide … Ground resonance is an imbalance in the rotation of a helicopter rotor when the blades become bunched up on one side of their rotational plane and cause an oscillation in phase with the frequency of the rocking of the helicopter on its landing gear. The effect is similar to the behavior of a washing machine when the clothes are concentrated in one place during the spin cycle. It occurs when the landing gear is prevented from freely moving about on the horizontal plane, typ…
