Evaluation of Dimensional and Aerodynamic Parameters for an Aircraft Radio Controlled through Genetic Algorithms and Design of Experiments

Abstract

This paper presents a study of aircraft configuration TKV2012 that is more optimized as possible in all aspects of stage length, questions and restrictions established by the SAE Co mpetit ion BRAZIL Aero Design 2012. The analytical method for estimation of the aircraft aerodynamic coefficients was performed using the linear appro ximation to the theory of Multhopp. Design of Experiments (DOE) was used integrated into the genetic algorith m through the interface ModeFRONTIER®, version 4.3, the company Esteco®. We used the algorithm and Planning SOBOL MOGA II, with about 28 input variables, given the requirements: project report (containing plants and forecast payload), oral presentation, maximu m loaded weight, high structural efficiency, "accuracy" Predict ion Weight Loaded (Accuracy Project) and bonuses. The primary outcome variab le was the total score, since the goal was to maximize their. The results allowed to identify and optimize the d imensional parameters of the aircraft, as well as signaling the main factors that influence the total score, helping to define the configuration of the aircraft 2012.
