Active Vibration Control Systems Contact Us

Active Vibration Control SystemsLORD Active Vibration Control Systems (AVCS) reduce vibration in the helicopter fuselage generated by the main rotor. Our AVCS provides state-of-the-art, patented algorithms that control steady state and transient vibration, even during start up. In the system, accelerometers measure aircraft vibration levels and signals are sent to a centralized computer. The computer interprets the signals and sends commands to force generators located throughout the aircraft. These force generators create "anti-vibration" that stops the progression of vibration due to the main rotor.
