Advanced Blade Sections for High Speed Propellers

As surface ships are required to achieve higher speeds to meet their mission requirements, many still have intermediate speed endurance requirements that necessitate higher efficiency than some high-speed propulsor options con provide. This effort looks into developing propellers with blade sections that have the efficiency characteristics of conventional submerged sub-cavitating propellers at low and inte1mediate speeds but can transition to the super-cavitating mode for highspeed operation without encountering thrust breakdown.
