Design Parameters Affecting the Accuracy of Isothermal Thermocouples

Abstract

The report presents an analytical study of the isothermal thermocouple commonly used on ballistic reentry vehicles to obtain the flight test data necessary to determine the thermodynamic performance of the heatshield. The objective of this study is to investigate the thermocouple design parameters and techniques that contribute to the instrument's accuracy. These parameters include the thermocouple wire diameter, the isothermal length, the lead wire length, the electrical insulation thickness, the type of heatshield material, the thermocouple depth, and the interference effects in multiwire plugs.
