Abstract(s)
Este trabalho consistiu no projeto e construção de um veleiro autónomo de
pequena escala. No início do trabalho, é feito um estudo acerca dos diferentes tipos de
veículos autónomos, dando mais enfase aos veleiros. Em seguida, é iniciado o projeto do
casco do veleiro, aplicando conceitos básicos de Arquitetura Naval. A forma do casco é
desenhada com recurso ao programa DELFT Ship Free, onde são realizados estudos
hidrodinâmicos do mesmo. Posteriormente é retratado a construção do casco projetado,
com recurso a materiais compósitos e impressão 3D de componentes do veleiro. São ainda
descritos os sensores, controladores, atuadores e programação desenvolvida para o
veleiro. É também realizado um estudo sumário da estimativa de consumos e autonomia
do sistema. No final, encontram-se os resultados obtidos das provas de mar efetuadas ao
veleiro.
This work is the project and construction of a small scale sailboat. It starts with an overview of the major types of unmanned vehicles. Then, we introduce the subject of designing the hull shape using naval architecture principles. The hull shape was drawn using DELFT Ship Free, where some hydrostatic and hydrodynamic studies were also made. The hull was built using steel reinforced composite materials and the peripheral systems were made using a 3D printer. A brief description of the electronic parts of the system is made, with emphasis on the sensors, actuators and microcontroller used. Some estimates are made on the cost of the project and the prototype, as well on it’s autonomy. Finally we present and discuss the results obtained in the testes and competitions where the sailboat was used.
