Rebuilding and Modeling of a Thermal Radiation Source
Abstract
This report describes improvements to a U.S. Army Research Laboratory Thermal Radiation Source (TRS). This TRS unit is an aluminum powder/liquid oxygen torch incorporating a tailored combustion chamber to flatten the flame and is intended to be installed in ARL 2.44-m shock tube. The combination of a TRS within a shock tube will provide the Army a facility for modeling a larger facility, conducting blast/thermal synergism experiments, and testing nuclear survivability of military equipment, components, and materials. Modifications made to the original TRS included installation of a new divert valve, change in the aluminum tank pressurization and aeration system, and pneumatic actuators. These changes significantly raised the radiation level and stability. A major operational change was computer control over the TRS sequence timer and data acquisition system. Parts of the TRS have been mathematically modeled. Methods to characterize the radiation output are described.
