A turbine shroud cooling system used in a gas turbine engine for controlling tip clearance between a turbine shroud assembly and turbine rotor blades comprises a cooling air passage for selectively directing a cooling air flow between components to be cooled and a turbine shroud support assembly for controlling the tip clearance and then later re-directing the cooling air flow to cool a downstream turbine component.
Système de refroidissement d'enveloppe de turbine utilisé dans un moteur à turbines à gaz, qui permet la régulation de l'espace séparant l'ensemble enveloppe de turbine des pales de rotor de la turbine. Ledit système comporte un passage d'air de refroidissement destiné à diriger sélectivement un flux d'air de refroidissement entre des composants à refroidir et un ensemble de support d'enveloppe de turbine pour réguler l'espace au bout des pales, puis à rediriger ultérieurement le flux d'air de refroidissement pour refroidir un composant de turbine situé en aval.
