Patent ID: 10486833

Abstract:
The present invention relates to method for monitoring an engine (1) of an aircraft (2) operating in a given environment. The invention is characterized in that it comprises the implementation, via means for data processing (31), of the steps of: (a) receiving a sequence of n-tuples (x1-exec. . . xn-exec; yexec) of physical-parameter values relating to said aircraft (2) engine (1), including at least one endogenous parameter specific to the operation of the engine (1) and at least one exogenous parameter specific to said environment; (b) For each n-tuple (x1-exec. . . xn-exec, yexec) of the received sequence, calculating, according to a regression model, a standardized value (yexec-norm) of the endogenous parameter in relation to the exogenous parameters; (c) identifying at least one stabilized phase in said normalized sequence of n-tuples (x1-exec. . . xn-exec; yexec-norm) from a set of phase signatures; (d) for each stabilized phase, calculating the mean values of the physical parameters on the portion of the sequence of n-tuples (x1-exec. . . xn-exec; yexec) corresponding to the stabilized phase, in order to obtain an n-tuple (x1. . . xn; y) defining a recurrent point of said flight of the aircraft (2).
