Structural design of the wing for URCUNINA (UAV)

Abstract

The structural design of the wing for URCUNINA (UAV) was carried out. The preliminary design was conducted using aerodynamic restrictions to pass into a detailed design by a structural analysis. For this porpoise CFD simulations were accomplish to obtain the loads over the wing, the usage of a process to transform the CFD output into information that could feed the FEA model was accomplished. This process include data collection, Matlab extrapolations, polynomial fits and construction of the V-n diagram to obtain proper data that work as input for the FEA. The analysis was done in the software ABAQUS CAE. The comparison of 3 different configurations of layup give the tools to decide the configuration used as a proposal after being evaluated using displacements and failure theories.
