Abstract

693,727. Centrifugal compressors and radialflow turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. April 25, 1951 [Jan. 25, 1950], No. 9698/51. Divided out of 693,686. Classes 110(i) and 110(iii) A diffuser system for a certrifugal compressor or a nozzle system for a radial inward-flow turbine comprises inner and outer walls 4, 5 spaced to provide between them an annular flow passage, at least one of the walls having its inner surface defined by a hyperboloid of revolution of one sheet, and radially extending stator blades 6 of which the roots lie on the straight line generators of the hyperboloid. The hyperboloid shape may be locally modified adjacent the entry or exit. The rotor 1 may be as described in Specification 693,686.
