Using specially developed dynamometer, hydrodynamic increase in inertia was determined for variable-pitch propeller under load at various pitch settings and operating conditions; tests also were made under "still water" conditions; effect of amplitude of oscillation and propeller Reynolds number on hydrodynamic inertia is small; influence of propeller load is also small over normal range of operation; it seems that hydrodynamic inertia can be determined to reasonable degree of accuracy by still water tests with nonrotating propeller.
