We carried out 2-D cascade tests of multiple-circular-arc (MCA) blades with a relatively high camber angle of 56 deg. in the region of inlet Mach number(M_1) 0.4≦M_1≦1.2, and with systematic variations of cascade geometry and incidence angle. Systematic data with respect to inlet Mach number characteristics of the cascade of MCA blades were obtained. The effect of stagger angle on inlet Mach number characteristics was discussed in the second report. In the present report, we discuss the following on the basis of experimental results. 1. the effect of inlet Mach number on the relation ship between incidence angle and parameters of cascade performance (incidence-angle characteristics). 2. the effect of stagger angle on incidence angle characteristics. 3. the relation ship between incidence angle and critical inlet Mach number. 4. the relation ship between stagger angle and stall incidence angle, reference incidence angle. 5. the relation ship between limit in the available range of operation of the incidence angle and inlet Mach number.
