Supersonic Wind Tunnel Control
As part of a large overall project to repair and upgrade the UT Arlington supersonic wind tunnel, a new program was created to maintain a constant stagnation pressure in the plenum chamber upstream of the test section. The program was written in a LabVIEW environment, and can be applied to other wind tunnels with very few changes having to be made. The details behind this PI control program and its corresponding simulation program are shown in AIAA paper 2008-852. The simulation and a basic version of the program are available for download below. It is essential to thoroughly read the AIAA paper to understand how to use the simulation program properly to determine suitable PI control values. A more accurate program will be completed soon.
