DEVICE FOR COOLING A TURBOMACHINE CASING

The thermal shrinkage of a casing (2) to regulate as best as possible the internal play between the rotor and the stator is carried out by a ring (4) fixed onto the skin (2) rather than by a circular ramp at a distance therefrom. The ring (4) comprises, between a collection box (8) and the skin (2),...

Zusammenfassung:The thermal shrinkage of a casing (2) to regulate as best as possible the internal play between the rotor and the stator is carried out by a ring (4) fixed onto the skin (2) rather than by a circular ramp at a distance therefrom. The ring (4) comprises, between a collection box (8) and the skin (2), a foraminous plate (7), placed on an opening of the box (8) parallel to the skin (2) and at a short distance, in order to impose invariable and known ventilation conditions.
