Abstract

628,052. Centrifugal compressors. DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and MOULT, E. S. April 29, 1947, No. 11500. Drawings to Specification. [Class 110(i)] Disc-supported bLades: guide blades.-In order to reduce the shock losses on impact of air or gas with the blades of a high-speed centrifugal compressor, the leading edge of each blade is wholly or partly cut back or inclined in the direction of air-flow to reduce the component of flow velocity, normal to the blade edge at the outer parts of the blade. The resulting blade edge may be curved, or formed of one or more straight lines, and may be arranged to give a constant Mach. number at all parts. Fixed guide vanes may be necessary to swirl the air approaching the impeller in order to make it enter the blades at the correct angle; they may be formed to give greater swirl at greater distances from the axis. The entry portion of each blade is in the form of a helix. The additional advantages of reduced centrifugal force and increased natural vibration frequency are obtained. Specification 578,190 is referred to.
