Method for making a blade ring
A method for making a blade ring includes producing an outer shell of a blade ring by setting a blank using a plasma-forming process on a frame that is then removed. The tips of the blades are well embedded in the ferrule independently of their profile, such that the aerodynamic performances do not...
