Abstract
Лопастная система водометного движителя, содержащая ступицу и расположенные на ней лопасти с входными и выходными участками, выходные участки лопасти имеют волнистую структуру выходной кромки, помещенная в неподвижный цилиндрический насадок, отличающаяся тем, что в насадке расположены неподвижные лопатки противоположного направления по сравнению с направлением профиля лопасти, и фронтальная площадь неподвижных лопастей составляет 0,1..0,5 фронтальной площади вращающихся лопастей.The blade system of a water-jet propulsion device containing a hub and blades located on it with input and output sections, the output sections of the blade have a wavy structure of the output edge placed in a fixed cylindrical nozzle, characterized in that the fixed blade in the nozzle has opposite blades in comparison with the direction of the blade profile , and the frontal area of the fixed blades is 0.1..0.5 of the frontal area of the rotating blades.
