YOKO LUCILA TAKANO E SILVA | | Publisher : | | | Bridge Center | | Article URL : |  | | | Abstract : | | | In the aerodynamic design, the team participating in the SAE
Brazil Aerodesign competition should basically develop a finite wing
capable of meeting the requirements established by the team, providing
the accomplishment of the mission. In this sense, this article aims to
design this device. Firstly, the aerodynamic area is structured for the
development of aerodynamic design. From this, one starts to choose the
best airfoil, in which a statistical method of selection of profiles is used
that fulfill the accomplishment of the mission, so that several profiles
are preselected and simulated. After this, an interpolation of the bestchosen profiles is performed, creating a new aerodynamic profile. This
profile is compared to the one used by the team in previous editions of
the competition. Next, an optimization software is used, which,
through a genetic algorithm, develops the wing most appropriate to the
project as a whole, that is, able to take off in a track fulfillment within
the specifications, with a minimum 10 pounds of load and with high aerodynamic efficiency. In addition, the sizing of a hyper-sustaining
surface, the flaps, is performed so that the aircraft is capable of
performing a reconnaissance mission so that the aircraft decreases its
aerodynamic speed while passing over the target. In this design,
several deflection angles are considered, as well as the percentage of
differentiated ropes, in order to reach the best drag-to-lift ratio.
Finally, the results of the wing simulation in CFD software are shown,
based on the choice of surface materials, and their importance with
regard to the positioning of the ailerons. | | Keywords : | | | - |
