Development of Calibration Instrumentation for Ablation Facilities

Abstract

Results are presented from a program conducted to develop calibration instrumentation for ablation facilities. The investigation included the development and evaluation of a transient total enthalpy probe, a stagnation point heat-transfer probe, and total pressure probes. A laser shadowgraph was developed for visualization of the flow field. Testing was conducted in the AEDC-PWT arc heater test unit (5 MW). Uncooled probes swept through the flow at high velocity (10 to 40 in./sec) survived the severe heat-transfer conditions and the desired data were obtained. The results of this investigation and a description of the calibration instrumentation are presented.
