Flow control system in underwater parts of outboard/ship drives has asymmetrically profiled stator blade, drive housing parts between horizontal cavitation plate, drive shaft housing tunnel forward of upper propeller flow incidence surface

摘要

The system has an asymmetrically profiled stator blade (6) and drive housing parts located between a horizontal cavitation plate (2) and a horizontal drive shaft housing tunnel (3) and forward of the upper propeller flow incidence surface. Further asymmetrically profiled stator blades can be arranged on the drive housing forward of the upper propeller flow incidence surface depending on the size of the drive.
