METHOD FOR MONITORING A DEGREE OF CLOGGING OF THE STARTING INJECTORS OF TURBINE ENGINE Russian patent published in 2018 - IPC F01D19/00 F02C7/264 F02C7/22 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Method for monitoring a degree of clogging of the starting injectors of a turbine engine which includes a combustion chamber, in to which at least one starting injector supplied with fuel leads, wherein said injectors are designed to initiate the combustion in said chamber by igniting the fuel, and a turbine rotated by the gases resulting from the combustion of fuel in the chamber. Method includes the steps involving: the measurement (1100) of the exhaust gas temperature at the outlet of the turbine during the phase of turbine engine start and determination (1200) of degree of starting injector clogging on the basis of changes over time in the measured temperature. Invention also provides a system for controlling a degree of clogging capable of implementing the method for monitoring, as well as turbine engine and aircraft comprising such a system.

EFFECT: invention makes it possible to detect the clogging of starting injectors, as well as predict and anticipate the time, when the degree of starting injector clogging will reach a level at which it is impossible to start the engine.
