Abstract
L'invention entre dans le domaine des turbines axiales. Rotor de turbine axiale comportant une série d'aubes caractérisé en ce que les aubes sont reliées les unes aux autres, à leur sommet, par une couronne continue supérieure sans interruption comportant des moyens lui donnant une certaine élasticité circonfirentielle. L'invention s'applique en particulier au premier étage haute pression des turbines à vapeur de grande puissance.
