Análise de estabilidade longitudinal estatística de uma aeronave destinada a participar da SAE aerodesign

Abstract

One of the stages of a new aeronautical project includes static stability analysis, necessary to ensure that after a disturbance the aircraft returns to its initial position in. The aim of this work is to analyse the static longitudinal stabililty of an aircraft and, for that, a program in Python language is developed to help the Iguanas Aerodesign team in the mathematical analysis for the preparation of static stability reports for future aircraft projects. In order to demonstrate the effectiveness of the program, an analysis was carried out to verify the static longitudinal stability criteria of an aircraft designed by the team. The analysis showed that the aircraft is statically stable regarding the pitching movement, Cm0a, and of the heave moment angular coefficient, Cmαa. Furthermore, it was obtained the trim angle αtrim of the deflection plane δ for the elevator capable of keeping the aircraft in static equilibrium.
