MONITORING OF A DEGREE OF COKING AT DYNAMIC SEALS BY A STARTER MOTOR |
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; dynamic seals for providing a seal between the injection wheel and the fuel injection manifold; and a starter motor. The method comprises steps consisting in: during a phase in which the rotation of the gas generator shaft is initiated by the starter motor, measuring (1500) a current flowing through the starter motor and a voltage at the terminals of the starter motor, and determining (1600) a degree of coking at the dynamic seals, based on the current and voltage measured. The invention also relates to a turbine engine equipped with a system for monitoring the degree of coking. |
