Abstract
Techno-Sciences, Inc. (TSi), in collaboration with the Smart Structures Laboratory of the Alfred Gessow Rotorcraft Center at the University of Maryland (UMD), proposes to develop an innovative Active Pitch Link (APL) Technology for improved active rotor performance. The APL will exploit superior performance characteristics of new single crystal ferroelectric material, PMN, and nano-particle enhanced magneto-rheological (MR) fluid technology. This hybrid device efficiently marries two high-energy density electromechanical materials, PMN ferroelectric material and magnetorheological fluids, to provide full-scale rotor control. A low hysteresis high stroke PMN stack will be used to drive a hydraulic pump and develop a flow rate through a standard double-ended hydraulic actuator. Bidirectional control of the hydraulic actuator will be achieved using magnetorheological flow control valves arranged in a hydraulic power circuit.
