Turbine e.g. radial-flow turbine, has outer region strongly bent in direction of tangential plane, and inner region bent in direction of radius such that rotor blades are encased with guide plates, which are inward curved in spiral shape

摘要

The turbine has a set of rotor blades (3) aligned parallel to a rotation axis (1), where the rotor blades are aligned in a direction of a tangential plane and diagonally to radius. An outer region (15) is strongly bent in the direction of the tangential plane, and the inner region is bent in the direction of radius such that the rotor blades are encased with guide plates, which are inward curved in a spiral shape. The rotor blades exhibit a set of even surfaces with two axially running bending edges.
