Abstract
1475793 Centrifugal compressors OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 16 May 1974 [16 May 1973] 21689/74 Heading F1C In a supersonic centrifugal compressor for use in aircraft or in stationary installations, comprising a rotor 1 and a stationary diffuser 5, 6, the flow through the rotor passes successively through an intake region having a relatively small number of blades 7 arranged to produce slight deflection and divergence of the flow in order to stabilize the entry shock wave, a compression region having a larger number of blades 7, 8 causing the major deflection of the flow, and an outlet region where the flow is substantially radial. Additional blades 10 are provided in the outlet region. The diffuser comprises a parallel-walled or convergent bladefree portion 5 and a bladed portion 6 leading to a scroll (not shown). The entry angle of the diffuser blades may be between 6 and 12 degrees. The diffuser blades (13) may be angularly adjustable about shafts (14), Fig. 4 (not shown).
