Abstract

The present study shows the process followed in making the three-dimensional model and geometric documentation of a historical invention of the renowned Spanish engineer Agustin de Betancourt y Molina, which forms part of his rich legacy. Specifically, this was a wind machine for draining marshy ground, designed in 1789. The present research relies on the computer-aided design (CAD) techniques using Autodesk Inventor Professional software, based on the scant information provided by the only two drawings of the machine, making it necessary to propose a number of dimensional and geometric hypotheses as well as a series of movement restrictions (degrees of freedom), to arrive at a consistent design. The results offer a functional design for this historic invention.

Highlights

  • Agustin de Betancourt y Molina was a renowned Spanish engineer, who was born in the town of Puerto de la Cruz (Tenerife, Canary Islands) in 1758 and died in the Russian city of San Petersburg in 1824

  • Techniques of the plunger lock and of the mill for grinding flint was used; both were of the design of Agustin de Betancourt y Molina, notable examples of the historic heritage that makes up part of the legacy of the Spanish engineer

  • Agustin de Betancourt travelled to England during the second year of his stay in Paris (1788) in order to interview

Summary

Introduction

Agustin de Betancourt y Molina was a renowned Spanish engineer, who was born in the town of Puerto de la Cruz (Tenerife, Canary Islands) in 1758 and died in the Russian city of San Petersburg in 1824. Canaria Orotava de Historia de la Ciencia) has dedicated many years to compiling information on the engineer’s life and works, a digital project entitled “Betancourt” of the Fundación Canaria Orotava de Historia de la Ciencia and offered with free access [6]. This original and unedited research, which forms part of a doctoral thesis, continues efforts undertaken previously [7,8], in which a three-dimensional model with computer-aided design (CAD). It was made with the parametric design software Solid Edge ST7 [9]
