Vibration control Systems

LORD 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.

LORD offers both turn-key AVCS as well as AVCS components, adapting our product offerings to suit your specific vibration control needs. For more information, download a copy of the AVCS product bulletin.

Features and Benefits

• Reduce weight — Eliminates heavy passive vibration absorbers
• Improve comfort — Reduces occupant vibration levels in both the cockpit and cabin
• Improve performance — Enables expanded flight envelope within aircraft design limits and extended range
• Reduce direct maintenance cost — Lowers aircraft vibration levels resulting in less vibration-induced fatigue of structures and equipment
