Engineering Physics Annotation << Back Spectral-tomographic methods of diagnosis parameters of a hydrogen plasma ion engines Phylonin O.V. Iluhin V.V. Described spectrally tomographic diagnostic methods the parameters ion engines. It is shown how the inverse problem on the reconstruction parameters of the plasma flow ion engine can be reduced to an algorithm based on the integral equation Schlomlich. The description of the scanning system for two-dimensional data source for the reconstruction of the unknown parameters of the flows of hydrogen plasma ion and plasma thrusters where we get three parallel image spectra projections. A diagram of the experimental setup and optical circuit spectral-tomographic registration scheme optical experiments to determine the concentration of a component in plasma objects . In addition shows the optical scheme of the experimental setup for spectral-tomographic methods for the determination of local temperatures in a given section of the plasma flow, to determine the absolute intensity of the flare. The developed method of spectral-tomographic diagnostic parameters ion engines can be used not only in the laboratory, but also as revised staffing unit working fluid condition monitoring ion engine. Key words: ion engine, plasma diagnostics, spectral analysis, a few projections reconstruction, inverse problems. Contacts: E-mail: iluhin511@gmail.com Pp. 23-33.
