Abstract
A turbine engine including a channel for injecting a cooling air flow of a high-pressure turbine disk, opening into a cavity that is substantially isolated, upstream, from a cavity in which an air flow sampled at the output of a high-pressure compressor circulates, by a first labyrinth seal, and downstream, from a cavity communicating with the primary flow of the turbine engine, by a second labyrinth seal. The turbine engine includes channels communicating with the injection channel and opening through a static part of the first labyrinth seal between two lips of that seal, so as to allow an air flow coming from the injection channel to be injected between the lips.
