Abstract
Водометный движитель, содержащий цилиндрическую ступицу и расположенные на ней лопасти с входными и выходными участками, помещенные в неподвижный цилиндрический насадок, отличающийся тем, что шаг лопасти - переменный, причем шаг лопасти на входе больше шага лопасти на выходе, а в неподвижном насадке расположены неподвижные лопатки противоположного направления по сравнению с направлением профиля лопасти и утопленные в корпусе насадки.A water-jet propulsion device containing a cylindrical hub and blades with inlet and outlet sections located on it and placed in a fixed cylindrical nozzle, characterized in that the blade pitch is variable, with the blade pitch at the inlet being larger than the blade pitch at the outlet, and fixed blades are located in the fixed nozzle opposite direction compared with the direction of the profile of the blade and recessed nozzles in the housing.
