ABSTRACT:
The invention concerns an impact cooling device for the packing rings of turbine of a turbojet engine. The flow of cooling air entering an enclosure concentric to the rings, is divided into two distinct ventilation circuits by means of a ferrule of a generally circular shape, having corrugations, and with the amplitudes of said corrugations decreasing from upstream to downstream.
