A Design Calculation Procedure for Shock-Free or Strong Passage Shock Turbomachinery Cascades

Abstract

A previously described, inviscid design technique has been substantially improved to allow the generation of either shock-free, weak-shock or low total pressure loss supersonic rotor cascade designs. Improvements have been introduced in inflow-outflow boundary conditions, imposition of geometric constraints and in shock pressure rise specifications. Calculation examples are presented for precompression type rotor designs.
