Temperature Measurements through a Solid-Propellant Combustion Wave UsingImbedded Fine Wire Thermocouples

摘要

Temperature profile measurements have been measured through the combustion waveof burning solid propellant strands using imbedded fine-wire (75-micron diameter) thermocouples. The techniques necessary to construct, imbed, and measure temperature with this size and type of thermocouple were demonstrated. The experiments were performed at pressures ranging from 100 to 450 psi inside a high-pressure test cell designed for this type of operation. Surface temperature measurements have been estimated from the measured profiles for HMX, AN, and Double-Base propellants.
