Identification of Exhaust Species from the Combustion of LM and LMH Fuels.
Abstract
Studies have been performed to determine whether metastable chemical species are formed in the fuel-rich combustion of boron-fueled air-augmented propellant systems, and to evaluate the feasibility of using optical spectroscopic techniques to monitor the combustion processes occurring in rocket engines. These studies have utilized the specific emission obtained from rocket plumes and burners together with chemical analyses of the solid combustion products in order to provide detailed information concerning the chemical species present during the combustion of boron fueled propellants. Chemical analysis of the solid products indicates that a metastable B2H2O3 is present in significant amounts. Examination of the emission profile of plume structure indicates the feasibility of using optical spectrographic techniques to study qualitative changes in species concentration and perturbations in flow-profiles caused by changes in rocket hardware designs.
