Abstract:

This program consisted of the design, development, fabrication, and evaluation of a Hydrofluidic Yaw Axis Stability Augmentation System HYSAS. The objective was to develop a low cost, reliable, lightweight, flightworthy HYSAS with moderate performance and low-field maintenance characteristics compared to an electro-hydraulic SAS for jet powered AX class tactical aircraft. A system analysis was conducted that included a computer simulation of the Fairchild Aircraft Co. A-10 aircraft. From the results of the computer simulation, a yaw damper configuration was determined that improved flying quality characteristics by increasing dutch roll damping throughout the flight envelope of the AX Class Tactical Aircraft AXCTA,
