FULL AUTHORITY FAULT TOLERANT ELECTRONIC ENGINE CONTROL SYSTEMS FOR ADVANCED HIGH PERFORMANCE ENGINES (FAFTEEC)

Over the past three decades gas turbine engine technology for high performance, multi-mission aircraft has progressed from hydromechanical designs to full authority digital electronic control systems. Future weapon systems will require propulsion controls that are highly integrated with the flight control, and since the engine control then becomes part of the flight control system, safety will require fault tolerant capabilities. Realizing this, the Air Force sponsored the Full Authority Fault Tolerant Electronic Engine Control (FAFTEEC) Program¹ to identify the basic redundancy requirements in the design architecture of control systems that provide very high levels of mission reliability.
