Pacific Southwest Section Meeting Paper Submissions
Students studying astronautical engineering are expected to be capable of calculating an orbital trajectory based on initial conditions or data, but that doesn’t mean they have an intuitive feel for how each parameter affects the final orbit. By manipulating aspects of a spacecraft such as its launch conditions, thrust vector, or time of flight and immediately seeing the results of their manipulation, students can develop a sense of how various conditions affect spaceflight and make use of that intuition in the classroom and workplace.
The purpose of this project is to develop a tool that allows for easy to use and easy to understand demonstrations of orbital mechanics. We start with a simple n-body propagator, using our solar system as the model, to establish baseline trajectories with just the initial conditions. Initial conditions will be linked to launch conditions, providing students with an understanding of how the spacecraft started its journey. Once basic orbits are established, we introduce more complicated maneuvers such as thrusting and gravity assists to provide broader intuition on deep space travel. Once students have used this software they should have a much deeper understanding of how the elements of spacecraft and mission design work together to create an orbital trajectory and be capable of designing a basic deep space mission using the tools provided.
The software used to develop this will be Matlab. Matlab offers advantages in the development with its library of aerospace functions and the App Designer, which will simplify the GUI design considerably.
The purpose of developing engineering intuition is rooted in the Dreyfus  model of skill acquisition. This model considers intuition an essential part of transitioning from proficient to expert in any skill. Previous studies have shown that students who demonstrate intuitive understanding in their discipline correlate with higher GPA and more internship experience. This study hopes to provide a tool which develops intuition for aerospace engineering students; thereby improving their chances of success after graduation.
