Dimensionamento do sistema de dobrar asas de veículo: carro voado

Abstract

This work is part of a project of scientific initiation that involves the development of a flying car. For being of great complexity, it was necessary to divide the task into several systems, such as: power transmission system, which has been completed, folding wings that is the theme of this work, and other systems that still have not been specified. The mais objective is to design a light and secure system of opening and closing the wings. Without folding its wings, its purpose versatility as flying car will be lost, that is, the realization of this work is of great importance for this vehicle can travel on public roads. As results we propose a system actuated by stepper motors with three transmission stages consist of spur gears with helical teeth, which transmit the motion from one end to the other wing by means of roller chain. The overall system with all the elements which have been sized, has a weight of 98,79 kilograms, 49,39 kilograms being allocated in each vehicle wing. We present an estimated cost of approximately R$ 18.000,00 in total. This value reflects the quality and accuracy of the components used in the system. We can say that with the use of knowledge gained through the course, the goal was accomplished with the detailed design of the elements.
