Design and Test of a Small, High-Pressure Ratio, Axial Compressor with Tandem and Swept Stators

A small (22.2 lb/s), high-pressure ratio (1.83), axial compressor stage with a tandem stator has been designed and tested. The rotor was based on a 0.359-scale of a design made for NASA. The tandem stator consisted of a backward-swept first stage and a rectilinear (zero sweep) second stage. The scaled-stage overall performance was comparable to that of the full-size stage.
