heal.abstract	It has been shown that the inlet flow angles of nozzles and rotors in reaction turbines can be selected to be 40-degrees to 50-degrees for an inlet blade angle of 60-degrees and still obtain high isentropic efficiencies. With the blade design, that was investigated, relatively high pressure coefficients and isentropic enthalpy changes were achieved. Even for an inlet flow angle of 30-degrees no flow separation occurs for a well designed blade profile sketched for an inlet flow angle of 60-degrees. The part load performance of the investigated blade profile is expected to be very good because the large leading edge radius is quite insensitive to incidence angle variations. Inlet flow angles which yielded minimum cascade losses did not necessarily result in best stage efficiency designs.	en
