Abstract : Experiments were conducted with a scale model of an amphibious vehicle towed in calm water. Pressure distribution along the submerged bow and hull bottom was determined for a range of vehicle speed. A waterjet system with a bow intake and an axial flow impeller were then installed. The effect of the waterjet on bottom pressure distribution and height of bow wave were determined.
