Abstract
The present work aims to perform a study regarding the process of wing optimization using low-fidelity aerodynamics. The use of such tools is justified due to the large number of design variables and configurations that one needs to assess during the design process. In the present work, the computational framework can be summarized into two modules, one for the aerodynamic calculations and another for the optimization algorithms. The wing aerodynamic data are obtained through the linear lifting line theory. The optimization of the wing geometry uses the information from the aerodynamics module and applies different types of optimizers from an open source framework, known as OpenMDAO. The aerodynamic calculations are made by a Fortran subroutine, which is, then, connected to the optimization process through a Python script. The results obtained so far are quite encouraging and demonstrate the applicability of the present approach.
