Abstract/Summary

This research project focuses on the design and manufacturing of a rotating test stand for the Cal Poly Supersonic Wind Tunnel (SSWT). In order to establish essential design parameters, the project employs compressible flow isentropic relationships to calculate the Mach number within the test section and determine static pressures. This comprehensive effort integrates preliminary design and manufacturing processes, utilizing CAD designs and a range of machinery for component fabrication, while also highlighting initial testing of the rotating test stand's ability to withstand predicted aerodynamic loads. As part of the research's future work, rigorous structural stability testing and the implementation of flow visualization techniques, such as shadowgraph imaging, are planned to validate the design and optimize aerodynamic performance. The project aims to not only advance our understanding of aerodynamics but also offer valuable educational opportunities for undergraduate students.
