Desenvolvimento de um código computacional para análise da estabilidade em aeronaves rádio controladas

Abstract

In just over a century the aircraft evolved, especially duo to the economic and war sectors, to accord the needs of society. Aircraft design is not restricted to large industries. The SAE Brasil Aerodesign competition provides a competitive environment for graduate students to develop radio controlled aircraft. One of the steps in a new aircraft design includes stability analysis, which is necessary to ensure that after a disturbance the aircraft returns to its initial position. This work has a objective the development of a computacional code for stability analysis of radio controlled aircraft. As a demonstration of the program created, data from 2017 and 2018 aircraft of the Sol do Equador team, of the Instituto Federal do Piauí, are used and verified if they meet the stability criteria propposed in the bibliographies. After the analyzes, it was shown that both aircraft met the static stability, but in the dynamic analysis the aircraft presented unstable movement in the spiral vibration mode
