Özet:

In this thesis, a design effort for a jet vane based Thrust Vector Control (TVC) in the scope of mechanical design, computational analysis and validating test process is executed to be able to find an optimum CFD approach to this kind of work. To do that, a preliminary design phase is initiated with an already optimized geometry which provides an aerodynamic surface to be worked on. After mechanical design approach to the geometry with system requirements, some of the unverified aspects of the design are tested such as validating the materials and assembly connections. From the conclusive design, testing phase of TVC on multi-axis test stand has carried out. For this matter, design criteria of such test stand, calibration procedure, validation and corrective factors for measuring such as alignment, noise filtering has been investigated and conducted. A computational analysis survey has been performed that consisting couple CFD variable parameters which they are mesh dependency and turbulence models. According to collected data, the optimum CFD approach is determined by the error amount between them. As a result, a comparison of the experimental and computational data has been examined to find the loose ends and area of improvements for increasing the accuracy of data.
