Experimental Study of Full Authority Digital Engine Control (FADEC) System on Lycoming Engine
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
Full authority digital engine control (FADEC) is a system consisting of digital computer, called an electronic engine controller (EEC) or engine control unit (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. FADEC consist of HMU, Sensor and EEC. The proposed single chip SOC ASIC device integrates many diverse and improved functions required for interfacing with most types of FADEC Control sensors and actuators. FADEC or to expand the capabilities of a legacy FADEC system by addinga sensor or actuator. The same Smart Nodes can be applied without hardware change for controlling actuators, interfacing with sensors or a combination providing an affordable, scalable and reusable solution for Commercial and military engines, small or large, missiles and UAVs. True full authority digital engine controls have no form of manual override available, placing full authority over the operating parameters of the engine in the hands of the computer. If a total FADEC failure occurs, the engine fails. If the engine is controlled digitally and electronically but allows for manual override, it is considered solely an EEC or ECU. An EEC, though a component of a FADEC, is not by itself FADEC. When standing alone, the EEC makes all of the decisions until the pilot wishes to intervene.
