AN ANALYSIS OF IMPACTS ON MODEL PLANING BOATS

Abstract

This study aims to analyze the impacts encountered in boats in a towing tank. It was carried out on a planing boat model at Ata Nutku Model Experiment Laboratory in Istanbul Technical University. Through the developing technology more powerful engines and lighter composite structures led the boat speeds increased. Increase in speed will also increase the pressure, hydrodynamic loads, trim and dead rise angle of the boat. Additionally, apparent waves make the acceleration and shock problem on boats become superficial. These effects make the hydrodynamic acceleration problem very complicated. Also the boat which is operating at high speed over rough sea is exposed to severe repeated shocks. The first part of this study consists of the standards and methods for impact problem. The second part covers an experimental case, the results and includes comparison of the results

Keywords
