Abstract : Future advanced propulsion systems require improved control systems for the achievement of maximum overall weapon system effectiveness. Additional closed-loop control and flight-sensitive limiting functions are required to provide the necessary fuel economy and improved system response. The Advanced Hybrid Propulsion System Control Program has provided data necessary to achieve these requirements. The work accomplished during the program is presented. The performance requirements for an advanced turbopropulsion system were determined, and a control system to meet these requirements established. A comparison of fluidic, electronic, and hydromechanical technologies was made. A breadboard hybrid control system was designed, fabricated, and tested to demonstrate an approach for combining the three technologies. Bench tests at 1200 F environmental temperatures and engine evaluation tests were conducted and the results presented.
