Abstract [en]

University of Würzburg, Informatics VIII aims in developing a rocket simulator test bed in aspect of implementing a control algorithm for thrust vectoring concept. This thesis explains the idea of developing a miniaturized rocket model which is equipped with an actuating nozzle. The main content discussed in this project involves in designing a rocket prototype for thrust vectoring mechanisms where the control algorithm about to be developed can be implemented and tested for. From the various thrust vectoring mechanisms available, selection of mechanically actuated system is finalized because of its benefits in use. Here mechanical actuation is done with the help of servo supported by a bearing.The next phase is about describing the type of nozzle suitable for the work and proceeding with determination of the required parameters for the selected nozzle. By reviewing the available literature background, Bell shaped Convergent-Divergent nozzle is considered to be relevant and reasonably preferred for the thrust vectoring mechanism. Theoretical calculations were made for the specific criterion in respect with all technical details necessary for designing the nozzle. CAD model of the nozzle is then finalized and designed in Catia V5 R18 CAD software.Analyzing and visualizing the fluid flow parameters of the nozzle is done with the help of Ansys 14.5 software. Here the compressed air is used as the fluid flow medium. Analysis is made to find the pressure, density variation along the axis of the nozzle. The obtained analytical results are then validated with the theoretically calculated results. Once verification is done the components are given for manufacturing.Designed thrust vectoring setup should weigh very less for it to be lifted by the force produced by the nozzle. So the components are manufactured in a light weight material called PVC. The manufactured components are then assembled and tested in the laboratory.
