A turbojet turbine stage having air cooling of the turbine wheel disc is disclosed which has, on the one hand, devices for blowing in a flow of air A in the direction of the upstream surface of the disc (20) intended in particular to flow into the several passages delimited by the periphery (22) of the disc and by the shanks (14) and platforms (12) of the blade feet (11) of the wheel, and, on the other hand, a number of trough-shaped dampers (30) each of which is inserted in a passage and supported by its edges against the periphery of the disc while its back pushes against the platforms delimiting the passage. The upstream edge of each damper forms a peak (33) which extends beyond the upstream side of the disc.
