The development of Active Vibration Control Systems transformed both aircraft longevity and passenger comfort. This advanced technology uses a network of sensors and computer-controlled force generators to detect and counteract rotor-induced vibrations in real time. By continuously monitoring vibration patterns across multiple frequencies, the system automatically adjusts to minimize their impact on the airframe and gearbox. Studies have shown that AVCS can reduce vibration levels by up to 90% in certain flight conditions, reducing crew fatigue and extending the lifespan of sensitive avionics equipment. This innovation has been particularly crucial for medical evacuation helicopters, where patient comfort and stable conditions are paramount.
