Abstract:
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.
