Individual Blade Control of Hinged Blades Using Smart Structures

Kurzfassung

The feasibility of employing piezoceramic smart materials in active control of the higher harmonic vibration of hinged helicopter blades is investigated. The individual-blade-control concept is adopted to build feedback controllers that employ collocated smart sensors and actuators and are optimized to achieve damping augmentation for blade modes that significantly contribute to the airframe dynamic response. The results indicate that there is a parameter that will help the development of efficient smart rotors.
