Abstract
The annular array of radially extending blades on the rotor of a rotary fluid machine are tied together at generally their mid portions by interlocking separate tying members and projection pairs, wherein each projection pair includes facing projections on adjacent blades of the array. The tying members and projections have mating bearing surfaces that will provide a tangential force as a result of wedging produced by the centrifugal force acting upon the tying members during rotation of the rotor at rated speed, without restraining individual twisting of the blades about their radial extent.
