Servo controlled system is designed to provide very low natural frequency of 2-3 cps; analyses conducted for helicopter equipped with this LF system at both rotors and for helicopter with standard rotor attachments; comparisons of predicted variation of 3/rev cockpit vibration with air speed for helicopter reveal that 2-3 cps active isolation of both rotors can result in reduction of between 6 and 10 to 1 in lateral, vertical and longitudinal in-flight cockpit vibration.
