This report covers the developmental work accomplished on a program to furnish three fluidic servoactuators for a three-axis fluidic stability augmentation system FSAS. The servoactuators, designed to the specification for a helicopter flight control system, are classified as experimental but were designed to meet safety-of-flight requirements since they were intended for flight test in a hydraulic SAS. A servoactuator controlled by a two-stage fluidic servovalve was analyzed and designed. The servoactuator hardware was fabricated and bench tested. The servoactuator bench testing, using a load simulator, showed that the fluidic servoactuator meets all of the basic acceptance test requirements. The salient features are maximum force output of 100 lb, position frequency response flat to 7 Hz when operating with MIL-H-5606 oil supplied at 1000 psig, and a quiescent flow of 0.6 gpm.
