  • Gas turbine with stator shroud in the cavity beneath the chamber
    Patent number: 7036320
    Abstract: A turbomachine including a high pressure compressor with a downstream cone, a diffuser extending downstream by an inner casing disposed radially outside the downstream compressor cone, a combustion chamber disposed radially outside the inner diffuser casing, and a high pressure turbine whose rotor is connected to the downstream cone of the compressor by a connection drum, the inner diffuser casing and the downstream compressor cone defining between them an under-chamber cavity that is situated downstream from a discharge labyrinth in which cooling air flows downstream, wherein the engine also includes a stator shroud that is installed under the inner diffuser casing downstream from the discharge labyrinth.

  • Gas turbine with stator shround in the cavity beneath the chamber
    Publication number: 20050172642
    Abstract: The invention relates to a turbomachine of axis X and comprising, from upstream to downstream, a high pressure compressor whose rotor presents a downstream cone (4), a diffuser (3) extending downstream beside the axis X by an inner casing (5) disposed radially outside said downstream compressor cone, a combustion chamber disposed radially outside said inner diffuser casing, and a high pressure turbine whose rotor is connected to the downstream cone of the compressor by a connection drum, the inner diffuser casing and the downstream compressor cone defining between them an under-chamber cavity that is situated downstream from a discharge labyrinth (13) in which cooling air flows downstream, the turbomachine being characterized in that it also comprises a stator shroud (20) that is installed under the inner diffuser casing (5) downstream from the discharge labyrinth (13).
