This paper presents the active control of aeromechanical stability as a powerful means of simplifying rotor design in future helicopters. The mathematical simulation models are presented and the results are compared to flight test data. The active control of ground and air resonance has been fully validated with flight tests in the Super Puma MK2 helicopter which behaved in a highly efficient and robust manner. The active control for drive train stability had already been tested in the Super Puma MK2 with good results. The proposed controls are simple and easy to integrate in a conventional Flight Control System (FCS). The actuators available in the current FCS are sufficient as far as bandwidth required for the active control of aeromechanical stability is concerned. With the generation of fly-by-wire AFCS helicopters, active control of aeromechanical stability shall be very easy to develop at a low cost. To give an example, it is envisaged on the NH90 helicopter to integrate active control for air resonance and drive train stability in order to simplify the interblade damper technology.
