Abstract

724,115. Turbine and compressor blades and rotors. STALKER, E. A. July 15, 1949, No. 8121/52. Divided out of 724,073 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 16, 1950. Drawings to Specification. Class 110 (3). A turbine or compressor rotor comprises a plurality of hollow blades made from sheet metal and peripherally spaced about and secured to a hub, each blade comprising opposite convex and concave walls connected by a rounded nose continuous with each wall, the walls being braced internally by one or more bridging elements. The rotor is constructed as described in Specification 724,073.
