Three rotors were tested, to study flow and performance across loaded axial-flow blade rows. Principal design parameters varied were flow coefficient (0.29 < φ < 0.45), blade loading parameter at tip (0.25 < Dt < 0.66), and hub-tip radius ratio (0.4 < rh /rt < 0.8). Overall and blade element performances under noncavitating flow conditions are discussed in detail. Comparisons between the measured, three-dimensional design parameters and those computed from two-dimensional cascade correlations are made. A limited amount of performance obtained during operation of the rotors in unstable flow and cavitating flow conditions is presented.
