摘要
An aircraft turbine engine comprising at least one spool rotating at speed N1 and a monitoring system (1) comprising: a regulating module (REG) comprising at least one regulation measurement channel (A, B) suitable for obtaining a measurement (N1A, N1B) of the speed N1 and means for comparing the obtained speed measurement (N1A, N1B) with a thrust setpoint (N1cons) to provide a thrust status (EREG); and a module (ENG) for engaging a protection function of the UHT or ATTCS type of the turbine engine, the turbine engine also comprising a system for protection against overspeed in order to prevent the ejection of high-energy debris outside said turbine engine, the protection system comprising at least one overspeed measurement channel (AS, BS) suitable for obtaining an overspeed (N1AS, N1Bs) of the rotating spool of the turbine engine, the turbine engine being characterised in that the engagement module (ENG) comprises means for comparison of at least one overspeed obtained (N1AS, N1BS) with at least one reference speed defined according to the protection function to be engaged, said comparison means being configured in order to engage said protection function (UHT, ATTCS) according to the results of the comparison.
