Abstract

1518873 Turbine rotor blades MASCHINENFABRIK AUGSBURG NURNBERG AG 2 April 1976 [9 April 1975] 13387/76 Heading F1T An axial flow turbine rotor blade whose tip operates at supersonic velocity, e.g. for the last stage of a condensing steam turbine, has a longitudinal slot 1 dividing the tip region into a forward portion 2a and a rearward portion 2b trailing the portion 2a in the direction of rotation. Bracing members 3 may be provided.
