Özet:Ankara Wind Tunnel (AWT) operated by TÜBİTAK-SAGE is the only big sized wind tunnel in Turkey. The AWT was constructed in late 1940̕s but was not operated until 1993 when the tunnel was turned over TÜBİTAK-SAGE. Since 1993, a series of modernization work has been undergoing in order to match the demands of the 21st century. In wind tunnels, models are positioned by special mechanisms that are instrumented to get the test data specific to the test performed. Models are assembled from their rear sides on these mechanisms called model support systems in order not to influence the flow around them. In this thesis, a conceptual design of a 6 degrees-of-freedom model support system for AWT is accomplished. A detailed system model is developed for the controller design. A force controller to perform store separation tests in real time is designed, tuned, and validated with computer simulations.
