Engine Control / FADEC

Emissions, fuel burn, lifecycle cost, reliability and safety continue to be the key drivers influencing the large commercial aircraft industry. To meet these requirements, and because of its efficiency and reliability, the gas turbine engine is the predominant choice for aviation propulsion.

For most aviation applications, however, a gas turbine engine must provide predictable thrust performance over the entire operating envelope of the engine, covering altitudes ranging from below sea level to tens of thousands of feet above. These altitude changes, along with differing flight speeds from takeoff to supersonic velocities, result in large variations in engine inlet temperature, inlet pressure, and exhaust pressure.

These large variations in engine operating conditions, coupled with the need for precise thrust control and highly reliable operation, create a significant challenge for the design of engine control systems, especially given the complexity of the engine itself.

A Full Authority Digital Engine Control is a system consisting of a digital computer and ancillary components that control all aspects of an aircraft’s engine and propeller. The FADEC uses speed, temperature, and pressure sensors to monitor and control the status of each aircraft engine and adjust the various parameters to achieve optimal performance of the engine. FADEC systems are considered an essential part of the engine and propeller control and this precise control of the combustion process often results in decreased fuel consumption and increased horsepower.

Our approach to supplying pressure modules for engine control / FADEC relies on an integrated strategy that satisfies the functional requirements of the modern jet engine while helping to ensure lower emissions, fuel burn and cost, along with increased reliability and safety.
