MEASUREMENT OF THE PRESSURE FLUCTUATIONS IN THE TEST SECTION OF THE 16-FOOT TRANSONIC CIRCUIT IN THE FREQUENCY RANGE FROM 5 TO 1000 CPS

Abstract

An investigation was conducted in the 16-Foot Transonic Circuit of the Propulsion Wind Tunnel Facility (PWT) to determine the inherent pressure fluctuations in the test section. Test results indicate that these pressure fluctuations are well within one percent of the free-stream dynamic pressure except at Mach numbers near 0.7. The relatively larger fluctuations near Mach Number 0.7 result from a higher power spectral density in the 500 to 700 cps frequency range.
