Abstract:
The newest version of a jet engine fuel control is called a FADEC - Full Authority Digital Electronic Control. The original fuel controls on early jet engines of the late 1940s and early 1950s were simply constructed and resembled a common gate valve connected to a throttle lever. Engines and controls became more sophisticated thru the 1950s and 1960s, better performance, more reliability, and increased safety became driving forces. The new electronic fuel controls will be even smarter, more precise, more accurate and more reliable than present day fuel controls and they will be with us for many years. This paper presents a short history of fuel controls, some of the objectives required for a successful FADEC system, a description of some of the hardware changes to meet these objectives, and an overview of some of the operational characteristics and system protection provided.
