METHOD FOR MONITORING THE STATE OF HEALTH OF AN AIRCRAFT TURBOMACHINE

Abstract: a method for monitoring the state of health of an aircraft turbomachine for a flight of interest vi, based on a setpoint vector xsc of input parameters relative to the turbomachine of interest in steady-state regime, the method using a database of values of input and output parameters in transient regime for a plurality of flights including the flight of interest, and values of input and output parameters in steady-state regime for a plurality of flights with the exception of the flight of interest. the transient data are used to estimate a transient prediction model f, at least one portion of the transient prediction model f then being used, associated with the steady-state data, in order to estimate a steady-state prediction model h of the turbomachine of interest for the flight of interest and to determine the behaviour, in steady-state regime, of the turbomachine for the flight of interest.
