The EOL tunnel was not modified to provide a good turbulence spectrum for this test. There were no obstacles placed in the tunnel to create turbulence. This was a simple comparison test of the hotfilms and data system to verify their basic operational status.
For the first test, on March 5th, probes p1, p2 and p3 were mounted on a vertical support, about 6 inches apart, with p1 on the top, p2 in the middle and p3 on the bottom.
For the March 6th test, probes p2 and p4 were mounted on the support, with p2 on the top, higher than its position on March 5, and p4 was the bottom probe.
Voltages were sampled at 2000/sec for 110 seconds at each wind speed, using the ISFF data system with a Diamond DMM-32X-AT analog card.
