High Temperature Thermocouple Installation Methods for Hypersonic Vehicles

Abstract

This presentation discusses the joint effort between the Air Force Research Laboratory (AFRL) and NASA Langley Research Center to establish a process for bonding type C and type K thermocouples to high temperature materials. Bonded samples of both type C and type K thermocouples will be tested in a combined thermal-vibration environment. A baseline and alternate installation method will be tested. The instrumented specimens will be mounted on a shaker and heated with quartz lamps. The specimens will be exposed to three different environments: a launch vibration spectrum, a re-entry vibration spectrum, and a high temperature degradation environment. The installation methods that are capable of withstanding these three environments will be considered for use in hypersonic flight testing.
