The measurements were made at a station 10.2 cm downstream of the engine nozzle exit. The NO measurements were made at two engine power settings, intermediate and maximum afterburning; the NO2 measurement was made only at intermediate power. The line-of-sight absorption measurements through the axisymmetric exhaust stream were converted to local values of concentration via an interative radial inversion computation. These in situ measurements are compared to NO sub x concentration values obtained by conventional probe sampling techniques using a chemiluminescent analyzer. (Author) 收起
