Multiple Fault Gas Path Analysis Applied to a Twin Spool, Mixed Flow, Variable Geometry, Turbofan Engine.
Abstract
This report presents the results of a study made to develop a multiple fault diagnostic system for a complex twin spool, mixed flow, variable geometry turbofan engine using Hamilton Standard's Gas Path Analysis Technique. Engine data from a detailed nonlinear simulation of a paper engine was used. A simple control mode is also presented. Using a weighted least squared estimation procedure, a number of possible diagnostic routines are developed taking into account sensor and control uncertainties. A figure of merit is defined and used to isolate the acceptable diagnostic systems.
