Studies on Transonic Double Circular Arc (DCA) Profiles of Axial Flow Compressor-Calculations of Profile Design,

Abstract

In this paper, the concepts and methods for design of high-Mach-Number airfoils of axial flow compressor are described. The correlation-equations of main parameters such as geometries of airfoil and cascade, stream parameters and wake characteristic parameters of compressor are provided. For obtaining the total pressure loss coefficients of cascade and adopting the simplified calculating method, several curves and charts are provided by authors. The testing results and calculating values are compared, and both the results are in better agreement. (Author)
