A simple, bottom-inlet, waterjet was designed for evaluation in a fifteen-foot, manned testcraft. To aid in the planning of the experiments to be conducted with this craft, a 1/4.828 scale model was built and tank tested. The impeller was a stock 4-bladed marine model propeller housed in a cylindrical duct. Model resistance and trim were measured over a range of speeds. Waterjet velocity; propeller thrust, torque and rpm; and static pressures in the inlet casing were measured at several speeds bracketing the drag hump. Model waterjet performance was compared to design predictions. (Author)
