Abstract
A turbine rotor having twisted blades, are, in the vicinity of their radiy outer portions integrally connected with each other to prevent any rotation in either direction of one blade in relation to its neighboring blades. The blades are prestressed during assembly by being un-twisted through an angle which is less than or equal to and in the same direction as the angle through which said blades would be un-twisted during rotation if they were free to rotate in relation to each other.
