Abstract

A digital electronic engine control (DEEC) system has been developed by Pratt and Whitney Aircraft for use on the F100-PW-100 turbofan engine. This control system has full authority control, capable of moving all the controlled variables over their full ranges. The digital computational electronics and fault detection and accommodation logic maintains safe engine operation. A hydromechanical backup control (BUC) is an integral part of the fuel metering unit and provides gas generator control at a reduced performance level in the event of an electronics failure. This paper will describe the DEEC features, hardware, and major logic diagrams.
