Abstract

The authors describe efforts at the US Naval Surface Warfare Center´s Hypervelocity Wind Tunnel No.9 to measure wind tunnel model surface temperatures using a commercially available infrared (IR) camera. IR camera measurements on a Macor model surface tested at Mach 14 in Tunnel 9 are presented, and the data are compared to vapor-deposited thermocouple measurements made on the same substrate. The IR data were collected using an Inframetrics Model 600 infrared camera and were reduced using the camera manufacturer´s software. The results of this analysis show the feasibility of making global nonintrusive heat transfer measurements using an infrared camera
