Abstract
This article is an impeller used in a water jet propulsion system utilized by ships such as hydroplanes. By rotating this impeller, the water within the concave portion on the bottom surface of the impeller is radially ejected to the outside of the impeller through the grooves on the bottom surface of the impeller. Therefore, it is possible to reduce the water pressure of the water that enters from the outside into the joint surface between the bottom surface of the impeller and the pump, and it is possible to make it difficult for water to enter the pump.
