Abstract:
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 Btu/sq 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.
