The Atılım University Department of Airframe and Powerplant Maintenance has been offering Civil Aviation education in English since 2012. In an effort to provide the best level of education, ATILIM UNIVERSITY demonstrated its merit as a role model in Civil Aviation Education last year by being granted a SHY 147 certificate with the status of “Approved Aircraft Maintenance Training Institution” by the General Directorate of Civil Aviation. The SHY 147 is a certificate for Approved Aircraft Maintenance Training Institutions. It is granted to institutions where training programs have undergone inspection, and the quality of the education offered has been approved by the General Directorate of Civil Aviation. With our Civil Aviation Training Center at Esenboğa Airport (our hangar), and the two Cessna-337 planes with double piston engines both of which are fully operational, as well our Beechcraft C90 Kingait plaine with double Turboprop engines, Atılım University is an institution to offer hands-on technical training in civil aviation, and one that strives to take the education it offers to the extremes in terms of technology. The Atılım university Graduate School Department of Airframe and Powerplant Maintenance is a fully-equipped civil aviation school to complement its theoretical education with hands-on training using planes of various kinds. Even before their graduation, most of our students are hired in Turkey’s most prestigious institutions in such a rapidly-developing sector. We are looking forward to welcoming you at this modern and contemporary institution for your education in civil aviation.

Abstract

In this study, two different well-known wind tunnel techniques; “Captive Trajectory Method “and “Grid Surveying Method “are simulated using Computational Fluid Dynamics (CFD) method. Time dependent behavior of a generic store during the release process from a delta wing under high transonic flow regime is determined. First of all, in captive trajectory simulation, simultaneous trajectory and attitude computations are accomplished by utilizing a reliable commercial flow solver called ANSYS Fluent. Secondly, aerodynamic grid database generation required for grid surveying approach is performed and the trajectory of the store is determined by using a standalone store separation module built in MATLAB Simulink. The numerical outputs are compared with available wind tunnel results conducted in Arnold Engineering Development Center. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.
