Abstract

628,263. Axial-flow compressors. BREGUET, L. Aug. 27, 1946, No. 25559. Convention date, June 1, 1943. [Class 110(i)] An axial-flow compressor comprises a stator and a rotor co-axially mounted with respect to each other and each is provided with circumferential rows of blades the rows being arranged in groups, each group consisting of a plurality of rows, groups of fixed and moving blades occurring alternately along the length of the compres. sor. The profile of each group of moving blades 3, 4, 5 is substantially a mirror image of the profile of the adjacent groups of fixed blades 3<1>, 4<1>, 5<1>, and the blades are curved and set to provide restricted inlets for the fluid, so that the passage allowed to the fluid between two successive blades in the same row offers, in a plane at right angles to the middle line of the passage, a section which increases in the direction of flow of the fluid. An intermediate blade 8 may also be included between the blades 4.
