This report covers the flight test of a three-axis Hydrofluidic Stability Augmentation System (HYSAS) coupled with a completely independent parallel attitude and heading hold for a CH-54B helicopter. The design goal was to evaluate the performance of the CH-54B Automatic Flight Control System (AFCS) with the electronic SAS replaced with a fluidic SAS and to establish the technical base for a fluidic inner loop and electronic outer loop control system.
