Abstract : Work on various problems in solid and air-breathing rocket development, e.g., submicron particulate formation, requires the input of kinetic data over wide temperature ranges on the oxidation reactions of refractory free radical species. Various approaches for producing these species and investigating their kinetics, using laser-induced fluorescence and high-temperature fast-flow reactors, are discussed. To demonstrate the feasibility of a new discharge-flow reactor method for producing such radicals, for kinetic studies, the kinetics of BO + O2 yields BO2+O was investigated. A rate coefficient of 4 times 10 to the -12th cu cm/molecule/s at 295 K was achieved.
