Modeling absorption spectra for detection of the combustion products of jet engines by laser remote sensing.

The absorption spectra of exhaust gases (HO, CO, CO, NO, NO, and SO) and aerosol (soot and AlO) particles were modeled at different temperatures for the first time and suitable spectral ranges were determined for conducting laser remote sensing of the combustion products of jet engines. The calculations were conducted on the basis of experimental concentrations of the substances and the sizes of the aerosol particles. The temperature and geometric parameters of jet engine exhausts were also taken from the literature.
