Abstract
707,298. Axial-flow compressors. ROLLSROYCE, Ltd. May 3. 1952 [Feb. 6, 1951], No. 2962/51. Drawings to Specification. Class 110(1) In a multi-stage axial-flow compressor of the type in which the working-fluid passage converges continuously from inlet to outlet, the velocity of the working fluid relative to the rotor blades is subsonic in the low-pressure stages (for example, the first five stages) and supersonic in the highpressure stages (for example, the succeeding four stages). The supersonic rotor blades have sharp leading edges and have their maximum thickness at half chord. The working fluid leaves the stator blading preceding each row of supersonic rotor blading in a direction generally opposite to that of rotation of the rotor blading. The working fluid has substantially free-vortex whirl before and after the later stages of stator blading.
