This thesis investigates the effects of camber change on the mission adaptive wing of a structurally designed unmanned aerial vehicle (UAV). The commercial computational fluid dynamics (CFD) software ANSYS/FLUENT is employed for the aerodynamic analyses. Several cambered airfoils are compared in terms of their aerodynamic coefficients and the effects of the camber change formed in specific sections of the wing on the span wise pressure distribution are investigated. The mission adaptive wing is modeled structurally to observe the effect of span wisepressure distribution on the wing structure. For the structural design and analysis of the UAV under this study, commercial software MSC/NASTRAN are used. The structural static and dynamic analyses of the unmanned aerial vehicle are also performed under specified flight conditions. The results of these analyses show that the designed structure is safe within the flight envelope.

Keywords: Cambered Airfoil, Mission Adaptive Wing, Structural Design of a UAV.
