Abstract

5 9 6, 9 0 3. Axial-flow compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., BAILEY, W. and ROY, J. Aug. 3, 1945, No. 20076. [Class 110 (i)] A compressor comprises a row of high cambered impulse rotor blades 81 adapted to induce in the fluid flowing therethrough a high kinetic energy mainly in the form of a high swirl velocity, and one or more rows of low cambered reaction rotor blades C adapted to rotate in the opposite direction to the blades B<1> to convert the said kinetic energy into pressure energy. A row of low-cambered rotor blades, with or without a row of low-cambered stator blades may be interposed between the contra-rotating rows, and an initial row of stator blades A may be used to introduce pre-swirl. Since for efficient operation all the swirl cannot be taken out in the contra-rotating row C, a row of stator blades D may follow this row.
