Abstract

847,054. Turbine and compressor rotor blades. GENERAL MOTORS CORPORATION. Aug. 1, 1958 [Aug, 14, 1957], No. 24965/58. Drawings to Specification. Class 110 (3). In a turbine or compressor rotor, the blade tip shroud is formed of segments of hollow sheet-metal construction joined end-to-end at each blade-tip by interlocking tongues slotted to receive the blade tip. Key-pieces inserted inside the slots between the blades and the segments prevent separation of the segments and the blades. A metal channel is welded to the segment outer surface to provide a labyrinth seal adjacent the compressor case.
