Abstract

657,366. Axial - flow compressors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 9. 1949. No. 3541. Convention date, Feb. 25, 1948. [Class 110(i)] The diffuser in the annular delivery of an axial flow compressor is fitted with a ring of radially disposed twisted blades Adjacent blades are twisted in opposite senses. Fig. 10 is a circumferential section at the outer ends of three blades. The twist of blade 29 is opposite to that of blades 30. The blade passage on the left diverges from a narrow entry at the inner ends of the blades and converges from a broad entry at their outer ends. The blade passage on the right is similar but inverted.
