Full scale dynamometer tests were run on a series of
unshrouded propellers in the range of propeller diameters considered
practical for use on the side propulsion units of the
research submarine ALVIN. Measurements taken included static
thrust, torque, and RPM for various values of hydraulic power
input to the driving motor.
In other tests, propellers having 14 inch diameter and
20 inch pitch (the present ALVIN configuration) were compared
for static thrust as follows: conventional blade shape, unshrouded;
conventional blade shape in ALVIN flow-accelerating
nozzle unit; square-ended blades in ALVIN nozzle unit.
Recommendations are given concerning the proposed new
ALVIN side propulsion units.
