Optimization of the Drag Force of Planing Boat with Trim Control System Using Genetic Algorithm

Abstract

The control surface is an effective apparatus for improving the performance of planing boats and is considered an important element in the design of planing boats. Trim-tabs are placed at the transom to give better trim angle in order to diminish the resistance. In this paper, algorithm genetic (GA) is applied to find the trim, resistance and dearrise angle using Savitsky's formulas. The input data are all boat dimensions, including trim-tab data. The output results are trim angle, longitudinal center of gravity (lcg) and deadrise angle (β) and minimum resistance.

Obtaining the Practical Formula for the Trim-tab Dimensions to Reach the Minimum Drag for Planing Boat

“…Also, many numerical results on the planing hull carried out by CFD solver [27,28,29]. Drag minimization using trim-tab control system carried out by Ghassemi et al [30,31,32] on the planing boat.…”
