METHOD FOR DETECTING AN INCREASE IN THE RATING OF A LOW-PRESSURE TURBINE OF AN AIRCRAFT REACTOR DURING A CRUISING FLIGHT PHASE, AND ASSOCIATED DEVICE AND METHOD FOR REGULATING THE COOLING AIR FLOW RATE OF A LOW-PRESSURE TURBINE

摘要

A method for detecting an increase in the rating of a low-pressure turbine of a detection of an increase in the rating of a low-pressure turbine of a reactor of an aircraft reactor during a cruising flight phase, comprising measuring (100) the rating (N1) of the low-pressure turbine via a sensor. The method comprises determining (110) a rating gradient (G) of the low-pressure turbine from the measured rating (N1), comparing (120) said determined rating gradient (G) to a reference rating gradient (Gref), determining a positive or negative indication that the aircraft is under cruising phase conditions from flight parameters of the aircraft, and activating (160) an alarm if the determined rating gradient (G) is higher than the reference rating gradient (Gref) and if said received indication is positive.
