摘要： A method for monitoring a degree of clogging of the starting injectors of a turbine engine, which includes: a combustion chamber into which at least one starting injector supplied with fuel leads, the starting injectors being suitable for initiating the combustion in the chamber by igniting the fuel; and a turbine rotated by the gases resulting from the combustion of the fuel in the chamber, the method including the steps involving: the measurement, during a phase of starting the turbine engine, of the temperature of the exhaust gases at the outlet of the turbine; and the determination, from the changes over time in the temperature thus measured, of a degree of clogging of the starting injectors. A system for monitoring a degree of clogging capable of implementing the method, and a turbine engine including such a system.

摘要： The invention relates to a method (1000) for monitoring a degree of coking at the dynamic seals of a turbine engine comprising: a gas generator, comprising a rotary shaft and an injection wheel mounted on said shaft, an injection manifold, dynamic seals for ensuring a seal between the injection wheel and the injection manifold, and a starter, the method comprising the steps: measuring (1500), during a phase for initiating rotation of the shaft of the gas generator by the starter, a current flowing through the starter and a voltage on the terminals of the starter, determining (1600), from the measured current and voltage, a degree of coking at the dynamic seals. The invention also relates to a turbine engine comprising a system for monitoring a degree of coking.

摘要： The invention relates to a method (1000) for monitoring a degree of coking at dynamic seals of a turbine engine comprising: a gas generator including a rotary shaft and an injection wheel mounted on the shaft; a fuel injection manifold designed to convey fuel to the injection wheel; and dynamic seals designed to provide a seal between the injection wheel and the fuel injection manifold. The method is characterised in that it comprises steps consisting in: measuring (1100) the rotation speed of the gas generator shaft during a turbine engine autorotation phase, and determining (1200) a degree of coking at the dynamic seals, based on changes in the measured rotation speed over time. The invention also relates to a turbine engine equipped with a monitoring system.
