Abstract : Radiation from rocket exhaust plumes in the vacuum ultraviolet (VUV) spectral region (110-180 nm) is of considerable importance to The Air Force and the Defense Research Projects Agency. However, before emission features in a given spectral region can be used by systems, a target model relating radiation intensity to characteristic missle parameters such as fuel type, altitude, area ratio, etc., must be developed. Intensity measurements on the systems of interest are the best source of such a model, but since radiation from foreign missiles generally cannot be measured under controlled conditions, theoretical means using laboratory results must be employed. As part of such an approach, the authors have identified the radiation, and determined the mechanism leading to emission, from a number of laboratory mixtures corresponding to major reactant compositions found in plumes of hydrocarbon- and amine-fueled rockets. These laboratory reaction systems are atomic O/C2H2 and atomic O/atomic N/C-compound mixtures in a fast-flow tube reactor at 300 K and 0.8 to 10 Torr and self-sustaining flames of various hydrocarbon and amine fuels with O2 and N2O4 at 1700-2200 K and 0.8 - 20 Torr.
