METHOD FOR THE MONITORING OF A DEGREE OF COKING AT SEALS BY A GAS GENERATOR SHAFT |
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. |
