Background
The part of the water jet propulsion inlet channel connected with the bottom of the ship body is a complex transition curved surface, which is an important part for ensuring that fluid smoothly enters the water jet propulsion device and reducing inlet loss. The shape of the traditional connection form is jointly ensured by a ship body mounting base, an inlet flow channel and a grating, and the three parts have higher requirements on the processing precision in order to ensure the linear smoothness of the connection position. The grid of the water-jet propeller is used as an important protection component and is arranged at the bottom of an inlet flow channel of the propeller to prevent foreign matters such as waterweeds, stones and the like from being sucked and influencing the work of the water-jet propeller. The design of the grid is not only suitable for the arrangement of the intervals to meet the requirement of blocking foreign matter suction, but also has enough strength and toughness, but the grid which is too dense and too thick increases the inflow loss of the water jet propeller, so the design of the grid of the water jet propeller needs to balance the hydraulic loss and the strength requirement.
