One of the most important design considerations for rocket launchers is its maintainability and one of the most important parameter which affects the maintainability is wear in launchers. Therefore, for predicting the life-time of a launcher, wear should be investigated beside other parameters such as fatigue etc. In this study, experimental and modeling of dry sliding wear in some mechanical parts of a typical rail launcher, used in helicopters, were made. Firstly, measurements about the material loss, which is generated during firing of missiles, were made on launcher components which have interfaces with missile. Then, these results were used to simulate the wear phenomenon by using a commercial finite element program, ANSYS. By the help of finite element model, crack initiation period depending on wear is tried to be evaluated without making additional firing tests.

Ballistic penetration of hardened steel plates Deniz, Tansel; Yıldırım, Raif Orhan; Department of Mechanical Engineering (2011) Ballistic testing is a vital part of the armor design. However, it is impossible to test every condition and it is necessary to limit the number of tests to cut huge costs. With the intro- duction of hydrocodes and high performance computers; there is an increasing interest on simulation studies to cutoff these aforementioned costs. This study deals with the numerical modeling of ballistic impact phenomena, regarding the ballistic penetration of hardened steel plates by 7.62 mm AP (Armor Piercing) projectil...
Experimental and numerical investigation of a jet vane of thrust vector control system Söğütcü, Burak.; Perçin, Mustafa; Department of Aerospace Engineering (2019) Thrust vectoring is generally used in tactical missile systems when attitude control with conventional control systems is inadequate. One of the most widely used thrust vectoring method is to employ jet vanes in the divergent section of the rocket motor nozzle to have the desired thrust vectoring. In the present study, the flow over the jet vane of a thrust vector control system is investigated using both numerical and experimental techniques. Three dimensional, unsteady and viscous flow over the jet vane i...
Development of a sabot design tool for aeroballistic range testing Kafdağlı, Karaca Efe; Kayran, Altan; Department of Aerospace Engineering (2006) The aim of this thesis is to investigate the general design and analysis principles of sabots and to develop a sabot design tool. Structures which support and align the models in gun bore, and separate without disturbing the flight path of models are called sabots. In the scope of this study, structurally critical regions and loads acting on sabots due to acceleration in the gun are determined. To calculate the loads acting and to size the sabots, approximate relations are derived by the help of strength of...
Optimization of aeroelastic flapping motion of thin airfoils in a biplane configuration for maximum thrust Kaya, Mustafa; Tuncer, İsmail Hakkı; Jones, Kevin D.; Platzer, Max F. (2007-01-01) An aeroelastic flapping motion of thin airfoils in a biplane configuration is optimized for maximum thrust. Airfoils are attached to swing arms by an elastic joint, which is model led by a torsional spring. A spring-mass system is employed for the aeroelastic coupling. The stiffness coefficient and the mass moment of inertia of the airfoil are optimized for maximum thrust. A gradient based optimization method is employed in a parallel computing environment. Unsteady, low speed flows are computed in parallel...
Conceptual aerodynamic design of ramjet missiles Demiral, Ertan; Eyi, Sinan; Department of Aerospace Engineering (2017) The prediction of aerodynamic coefficients of missiles that have air-breathing components is a challenging task during the preliminary design phase. It is considerably important to estimate missile aerodynamic coefficients accurately at the beginning of design phase to avoid poor designs which could lead to redesign at later stages of the design process. In this study, firstly an improved method is developed to predict the aerodynamic coefficients of missile configurations with air-breathing components more...
