Thermocouples for Interior Ballistic Temperature Measurements
Abstract
Flamespreading processes during the ignition of ballistic events have long been studied by pressure measurements and visual records from high-speed film. While optical temperature measurements have been utilized, they are not useful much below 1500 K. This report describes a fine-wire thermocouple probe designed to measure gas temperature in a propellant bed over the range from the initial propellant bed temperature to over 2000 K. Several diameters of thermocouple wire are tested for survivability and time response in the simulated pressure-wave environment of ignition of a propellant bed. Examples of temperature histories during ignition of M30A1 and M43 propellants are also included. Ignition studies, Temperature, Primers, Flamespreading, Gun simulator
