Abstract
The invention relates to a method () 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 () the rotation speed of the gas generator shaft during a turbine engine autorotation phase, and determining () 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.
