Abstract

As the field of astronautical engineering continues to grow, the demand for workers having experience with thrust analysis and rocketry grows as well. The goal of this project is to design and manufacture a thrust table to be used in future projects involving high-power model rockets. The thrust table is designed using a rail system with extruded aluminum and aluminum base plate, and electronics based on Arduino to measure thrust and chamber pressure in the rocket engine. The data collected is then used in a Matlab model to predict the flight of the rocket. Initial testing shows the table returns reliable thrust measurement, but further testing is needed to improve measurements of chamber pressure. The next step in this project is to use the table to test nozzle properties’ effects in the thrust of the motors, and to optimize those properties for maximum thrust and efficiency.
