The results of a design study to define and analyze a hydrofluidic flight control system for helicopters, incorporating pilot relief modes, are presented. The system defined provides the pilot with stability augmentation in three axes, over the total aircraft flight envelope, and with pitch and roll attitude hold, heading hold, and altitude hold over the normal range of cruise airspeeds. To obtain a relatively simple, low-cost system, control panel switching, electrical display gyros for attitude and heading signals, and series servoactuators for both stability augmentation and outer-loop modes are used. The study results indicate that a simple hydrofluidic flight control system which will provide significant relief for the pilot can be mechanized. (Author)
