RE-ENTRY PHYSICS RESEARCH
Abstract
Preparations are discussed for the study of the rate of the radiative recombination of atomic oxygen and carbon monoxide and of the emission intensity spectral distribution accompanying the recombination to be induced by shock heating gas mixtures containing O2, O3, CO, CO2 and Ar. The topics of discussion include the construction and operation of optical and gas handling systems, the synthesis, stability and decomposition rates of ozone in the gas handling system and preliminary experiments on the emission intensity of recombination. From the latter experiments, conducted at temperatures and pressures near 3000 K and 1 atm, a relative intensity spectral distribution curve was derived and found to be shifted to shorter wavelengths with respect to a similar curve derived from flame measurements at about 1500 K and comparable pressures. Also, measurements of the induction period preceding formation of measurable quantities of CO2 in shock heated gas mixtures containing CO, O2 and Ar were made at temperatures between 1450 and 2260 K and pressures as low as 0.01 atm in a 24 in. internal diameter shock tube.
