A Device for Measuring Heat Transfer Rates in Arc-Discharge Hypervelocity Wind Tunnels
ARO INC ARNOLD AFS TN
Heat-transfer-rate is one of the fundamental aerodynamic parameters which must be measured in Hypervelocity wind tunnel testing. Transducers which can perform this measurement are not commercially available therefore a device which can be employed for this purpose has been developed. This device can measure transient rates ranging from 1 to 1000 Btusq ft. sec for periods of 5 to 80 millisec it does not require run-to-run calibration and it is durable enough to withstand many tunnel runs without maintenance. Its performance has been proven through laboratory and tunnel tests and usage.
