The goal of this project was to design, construct, and conduct preliminary testing of a supersonic wind tunnel (SWT). In addition to observing supersonic flow characteristics, behavior of test objects can be investigated. The wind tunnel is an indraft type which uses the pressure ratio created between a vacuum chamber and the ambient air to generate a flow. The SWT has a modular design, allowing users to switch the channel contours with test-specific designs. The tunnel uses a Pitot-static probe system to acquire pressure measurements, which are used to calculate Mach number. A schlieren optical system was built to allow imaging of the flow and structures within. A humidity control system was designed and built to ensure performance without condensation under a range of ambient conditions.
