Surface Temperature Measurement Fidelity In High Enthalpy Plasma Test Facilities, Owen Plante

Graduate College Dissertations and Theses

The classification and study of thermal protection systems (TPS) relies heavily on the accurate measurement of surface temperature. The best way to measure surface temperature in ground test facilities is through optical pyrometery due to the non intrusive nature of this method. Optical pyrometric devices use the emission of a greybody curve to calculate temperatures. These devices are left susceptible to parasitic radiation coming from the plasma generated in ground test facilities. The parasitic radiation comes from the emission lines of the test plasma in the investigation region of the devices. The parasitic radiation from the plasma and short comings …
