Some Aspects of Compressor Stage Design

摘要

This paper gives two approaches to the problem, The first section deals with the direct problem of the performance of given compressor stages and indicates how the "blade sections, of various designs approach the stall point.nIn the second part, a method is presented which combines the solutions of the indirect and direct problems. This method enables a designer to determine stages which will satisfy the imposed design conditions and to predict their off design performance up to the stalling point. These stages differ in the distribution of pressure rise between rotor and stator. This choice of reaction 1b investigated in the off design performance and may enable the designer to choose the optimum blading.
