| description | 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.
L'invention concerne un procédé (1000) de surveillance d'un degré de cokéfaction au niveau de joints dynamiques d'une turbomachine comprenant: -un générateur de gaz, comprenant un arbre rotatif et une roue d'injection montée sur ledit arbre, -une rampe d'injection, -des joints dynamiques pour assurer une étanchéité entre la roue d'injection et la rampe d'injection, et -un démarreur, le procédé comprenant les étapes consistant à: -mesurer (1500), au cours d'une phase d'amorçage de la rotation de l'arbre de générateur de gaz par le démarreur, un courant traversant le démarreur et une tension aux bornes du démarreur, -déterminer (1600), à partir du courant et de la tension mesurés, un degré de cokéfaction au niveau des joints dynamiques. L'invention concerne également une turbomachine comprenant un système de surveillance d'un degré de cokéfaction. |
