ADJUSTMENT OF ECCENTRIC RADIAL CLEARANCES IN TURBOMACHINES

摘要

Cooling or heating means are associated with a limited peripheral stator zone of a turbomachine, in such a way that a peripherally non-uniform temperature distribution brings about a deformation of the stator which reproduces the deformations of the rotor at various stages of use of the turbomachine. The longitudinal axes (R,S) of the stator and rotor thus coincide with one another. ……
