A SIGNIFICANT NUMBER of the helicopters presently in the US Army inventory are inherently unstable and use pressurised hydraulic fluid in the hydromechanical flight control system. The development of a hydrofluidic stability-augmentation system which can be integrated into the helicopter primary control system, offering promise of improved reliability, maintainability, and reduced cost over conventional electromechanical stability augmentation systems, has been accomplished.
