Plume Observables and Countermeasures
Abstract
Further work on the radiative behavior of rocket exhaust plumes at high altitude is reported. Comparisons of calculated flow fields with wind- tunnel test data indicate that agreement is generally satisfactory if allowances are made for absolute calibrations of the data. Calculations of a plume emission according to some proposed mechanisms have been performed. It appears that production of OH by O atom attack on secondary H atoms in hydrocarbon fragments can result in substantial chemiluminescent emission from H2O formed by subsequent reaction of the OH. Some semi-quantitative analogies between rocket exhaust flows and material releases in the upper atmosphere are discussed, and derivations directed toward comparing collision energy distributions at very high altitudes are presented.
