A Review of the Hydrodynamic Relationships of Lower Foils in Hydrofoil Vessels(Applied example)

One of the many types of vessels that have been exploring, designing, and exploiting for many years are Hydrofouil vessels .Hydrofoil vessels, despite to have The Irrefutable Benefits, because of their special structure, which, when separated from the water surface, are mounted only on two structures called hydrofoil, in different moments, such as when separating from the water surface, forming a cavitation, wave Or change the speed of falling into the water, so eliminating or discount this disadvantage will make the Practical and Advantages bold this is type of boat And can be used to build and operate Hydrofoil vessels and create a real place for them among other types of vessels.. In this paper, with the help of the experience gained in the design and construction of a one-meter hydrofoil boat and available information, longitudinal instability and methods for reduce it in this type of vessel are investigated in order to be a step in their better design.
