Abstract
Intrusive probes are critical tools in supersonic wind tunnel testing, enabling direct measurement of flow properties such as pressure and heat flux. To support these measurements, a single-axis intrusive arm was designed and implemented in the Missouri S&T Supersonic Wind Tunnel. The system is designed to maintains precise probe positioning, while withstanding the aerodynamic loads, and preserving a dynamic seal between the test section and ambient environment. Its modular design accommodates a range of probe types for various research applications. This paper presents the design methodology, including structural, mechanical, and aerodynamic considerations, and details the integration process. System performance was validated through a series of tests using a total pressure probe, which confirmed stable Mach 3 flow across the test section and demonstrated the arm's ability to deliver accurate, repeatable measurements. The addition of the intrusive arm significantly enhances the facility's diagnostic capabilities, providing a robust platform for advanced supersonic flow studies.
