SPECTRAL EMISSIVITY OF FLASH COMBUSTION REACTION STUDY PROGRAM
Abstract
This study was initiated to provide the additional data required on maximum intensity, spectral distribution, duration, and efficiency of radiation emitted by high energy metal-oxygen reactions and the degree of control that might be achieved over these characteristics. In brief, the study has shown: (1) several reactions produce brightness temperatures above the approximate threshold temperatures for neodymium (3500 to 5000 K) and ruby (5200 K) with a maximum of 600 K achieved; (2) the brightness temperatures are a strong function of pressure with highest temperatures achieved between 2000 and 50,000 psi; (3) except in the early stages of unpressurized reactions where line and band emission are present, the spectral distribution is a continium, but not necessarily a black body distribution; (4) the time duration of the flash can be controlled to within 1/2 to 3 milliseconds; and (5) that these reactions can be effectively used to pump high energy density laser systems.
