Method of designing a multi-stage turbine of a turbomachine

摘要

The method involves simultaneously modifying geometry of blades of different bladings for straightening wakes of a trailing edge of the blades, on radial dimensions of the blades. The bladings are angularly positioned with one another such that the wakes of stator blades impact with certain angle tolerance on a leading edge of the stator blades of a downstream stage for simultaneously realizing multi-stage aerodynamic coupling on the assembly of the turbine. An independent claim is also included for a method for fabricating a multi-stage turbine of a turbomachine.
