lateral vibration

lateral vibration

A vibration in a helicopter in which the rotor moves back and forth in a lateral plane, or side-to-side direction. Lateral vibration is often caused by an unbalanced main rotor.

Furthermore, Hitachi will achieve both high-speed elevator operation and a safe, comfortable ride by using braking equipment and a governor that safely bring the elevator to a stop, as well as technologies to prevent lateral vibration and to reduce the sensation of ear blockage caused by air pressure differences, it said.

A more subtle form of chipping and burring may occur from inadequate metal alloy, overly acute grind angles, excessive cant (shear) angles, and severe lateral vibration.
Before we could complete the third step, "Communicate," the aircraft developed a lateral vibration, minor at first, but steadily increasing in severity.
We knew there would be surface heaving and vibration, but we also estimated that lateral vibration would be minimal.
