Patent

CA 2640788

This invention relates to a turbine stator (5) for an aircraft turbine engine, comprising: - a stator wall (46) supporting a high pressure air injector (50) fixed on the downstream side; - an annular abradable element support (54) the lower radial end (54a) of which is fixed to said high pressure air injector and its upper radial end (54b) is fixed to said stator wall, such that they jointly delimit a cavity (58) under pressure. According to the invention, it also comprises at least one vibration damping device (74) located in said cavity (58) under pressure, said vibration damping device being in contact with each of the two elements taken among said stator wall (46) and said annular support (54).
