Abstract

Изобретение может быть использовано в качестве движителя для надводных, подводных и воздушных судов, аэроглиссеров, судов на воздушной подушке. Для уменьшения воздействия кавитации на гребной винт при работе за счет создания защиты лопасти из ламинарного потока жидкости в гребном винте каждая из лопастей выполнена с дополнительными водорезами, расположенными на передней поверхности лопасти по направлению ее движения от рабочей кромки винта.The invention can be used as a propulsion device for surface, underwater and aircraft, airboats, hovercraft. To reduce the effect of cavitation on the propeller during operation by creating a blade protection from a laminar fluid flow in the propeller screw, each of the blades is made with additional cutwaters located on the front surface of the blade in the direction of its movement from the working edge of the screw.
