Abstract: In order to study atomic spectroscopy in the diamond of the plume, a kerosene-oxygen flame on a lamp was used to simulate the plume of the liquid oxygen/ kerosene rocket engine, the ferrocene dissolved in the kerosene was used to simulate the Fe erosion of the engine The different experimental spectra of iron in different concentration were obtained respectively, the simulation results of the experimental ones were also presented The experimental results vary with the concentration; the simulation result fits satisfactorily for the measured one, which validates the simulation code of atomic radiation spectrum in the plume The qualitative study lays experimental and theoretical foundation for the research of engine diagnosis based on plume spectral analysis
