Abstract
Cascade tests were performed on models of the stator
(nozzles) and rotor blade rows of a high deflection, singlestage,
axial-flow impulse turbine. The tests were performed
at the Rectilinear Cascade Test Facility of the Propulsion
Laboratories, United States Naval Postgraduate School. The
results of these tests were compared with the performance
data of the actual turbine. The comparison showed that
profile and mixing losses, though not negligible, constitute
only a small percentage of the overall rotor loss. Also,
the inlet flow angle at which the minimum loss occurred for
the Cascade flow was significantly different from the inlet
flow angle at which minimum actual rotor loss occurred.
