Abstract : A controlled diffusion rotor blade section was designed for a supercritical inlet Mach number of M1=0.85 and a flow turning of 20. The blade section has been tested in a cascade wind tunnel under various inlet flow conditions and axial velocity density ratios. Detailed investigation about transition and separation points were carried out at the design and at two off design inlet flow conditions. The results are presented and discussed.
