Özet: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 materials approach and finite element solutions. Conventional sabots are investigated and new sabot geometries are designed to resist high accelerations. To achieve the desired test velocity without affecting the stability of the model is the main objective. Sabots should be as light as possible, to reach the desired velocity with minimum inertial load, in other words minimum gun chamber pressure. To obtain the less weight sabot geometry with enough strength to resist the loads acting, a computer tool is developed. Structural analyses are automatically performed by the help of the sabot design tool. The advantage of the design tool is to reduce the design engineer’s work time spent for routine analyses processes. The output of the tool, which is sabot geometry, should be evaluated as a result of preliminary design process, and can be used as an input for detailed design process. Detailed geometric modifications required for production can be applied on the tool output, and final product can be manufactured reliably and in the shortest possible time.
