  • Method for monitoring a degree of clogging of the starting injectors of a turbine engine
    Patent number: 10145262
    Abstract: 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.
