The purpose of this development effort was to achieve a practical implementation of a fluidic composite valve to replace the compression valve of a conventional shock absorber to improve vehicle control and performance. The effort was to result in the delivery of two breadboard adaptive fluid vibration dampers (shock absorbers) for Government evaluation. Program results include the sizing, design, packaging, fabrication and testing of several modifications of a compact, inertially controlled arrangement of three parallel fluidic beam deflection amplifiers controlling a vortex. Fabrication techniques of the fluidic valve included photo-etching of steel amplifier discs that were diffusion bonded to form a sleeve for a conventional valve spool that serves as the inertial sensor. A unique two-electrohydraulic servovalve test circuit was produced that provided constant flow control over a wide range of load variations. Two breadboard vibration dampers, one assembled and one unassembled, were delivered to the Government for evaluation. (DePo)
