Helicopter ground test
Did you know?
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… WebA new helicopter design must undergo thorough testing to ensure the reliability of the design with respect to vibration. A new design undergoing testing may encounter severe vibration while it is on the ground, preparing for takeoff. A similar problem may occur immediately after landing. Many helicopters have fully-articulated rotor systems.
