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.

High Performance Vibration Reduction

Parker Lord's Active Vibration Control System (AVCS) provides high performance vibration reduction in the helicopter cockpit and cabin. Using our state-of-the-art, proprietary algorithms, controllers and force generators, we can control rotor and powertrain generated vibrations from start-up through cruise and landing -- achieving reductions in cabin noise and in airframe or engine structural vibration.
