Objectives/Goals Increasing rocket engine efficiency requires maximizing the total impulse generated and tailoring thrust production to the mass of the rocket. By controlling the design elements of an engine, the total impulse generated can be maximized and the thrust profile can be customized. Last year, I demonstrated that optimal rocket flight parameters can be achieved by matching the rocket mass to engine thrust profile.The goal of this project is to identify critical design elements that can be manipulated to maximize total impulse and customize the engine thrust generation profile to optimize rocket lift. Methods/Materials I designed rocket engines that allowed me to investigate the contribution of the nozzle inlet shape, nozzle throat diameter and fuel core length and diameter to engine performance. All rocket engines were built to my design specifications and tested in a static engine test device that I built. Data from the test device was documented using a char...
