Projeto de uma embarcação tipo jangada - Análise de estabilidade

Abstract

The objective of this project is to use reversal engineering in designing a small boat classified as a wooden raft, which is the main instrument of transportation for the artisanal fishing that is done on the region of Ponta Negra-RN. Initially the fishing activity on the coast of the city Natal is introduced, it’s impacts on local economy and supplyment of the nearby market, introducting the main structure and propulsion methods and the building tools used by the craftsman. Subsequently the main theoretical studies are introduced and they will support all of the required hydrostactic calculation that are vital for the analysis on stability of the boat. After that the method for conception will be discussed and it’s simulation on auxiliary naval architecture softwares and it’s simulation on virtual environment, the designs on CAD that will be used on tilting studies. Finally the volume calculation will be presented alongside it’s weigth and analysed in various angles in order to compose the righting arm graphics for restorative and heeling momentum.
