Abstract

Dispositif de refroidissement des aubes d'une turbine à gaz fonctionnant sur le principe du thermosiphon en boucle fermée. Il comprend des aubes 42 du rotor 38 creuses et un circuit de refroidissement individuel en boucle fermée fonctionnant sur le principe du thermosiphon et utilisant la vapeur d'eau comme fluide de refroidissement, chaque circuit traversant un échangeur de chaleur 98 fixé sur un conduit d'huile axial 76 et solidaire du rotor, l'huile étant détournée du conduit à travers l'échangeur 98 pour refroidir la vapeur et l'huile chaude étant envoyée ensuite dans un échangeur de chaleur 124 dans lequel elle chauffe le carburant avant qu'il soit envoyé à la chambre de combustion 38. Application aux turboréacteurs et turbosoufflantes d'avion.
