Abstract: A blade ring of high circumferential speed for thermal axially passed through turbines, especially for the last stage of condensing steam turbines, having at least the radially outer portion of its blades lying within the range of transsonic flow or within the range of supersonic flow. Each blade of the blade ring changes from the profile at the foot portion of the blade toward the tip of the blade into a profile defined to a major extent by straight lines or by only slightly curved lines. This profile is about one half of its length at its upper region provided with a slot along the longitudinal axis of the blade. This profile which thus has two sections has one of these sections with its exit edge turned relative to the other section by an angle corresponding to the post-expansion of the supersonic flow into such a direction that the profile part with the exit edge lies in the flow-off direction.
