Özet:

In this thesis, the design and analysis of a hybrid trailing edge control surface of a fully morphing unmanned aerial vehicle wing having the ability to perform both camber and decamber morphings were conducted. The design of the control surface was done by CATIA V5-6R2012 package program. Two distinct designs, so-called open cell and closed cell designs were initially analyzed via Finite Element Method by using the commercial software ANSYS Workbench v14.0 in in-vacuo condition. Several trade-off studies including material, geometry and servo actuator feature variations were considered in order to decrease the weight of the control surface while still assuring the structural safety. The designed control surface was also considered as being under the aerodynamic load obtained from the planned flight mission profile of the unmanned aerial vehicle. During the Computational Fluid Dynamics analyses, Pointwise® V17.2R2 package program was used to generate the aerodynamic mesh, and Stanford University Unstructured (SU2) V3.2.1 open-source software was used as a solver. It was shown that the designed control surface is capable of performing both camber and decamber morphings both in in-vacuo condition and under the aerodynamic loading.
