Abstract:

We present the results of model experiments on recording the spectral characteristics of the emission glow of residual amounts of a substance on a blade of an aircraft turbojet engine after the mechanical impact of a foreign object. The spectra were measured by laser-spark spectroscopy, which made it possible to distinguish the emission lines of this substance against the spectrum of the blade material. This non-destructive testing method makes it possible to quickly diagnose the blades at the site of the aircraft inspection before a flight and to draw conclusions about possible destruction of the fuselage and the danger of the damage.

Keywords:

non-destructive testing, laser induced breakdown spectroscopy, structural material deformation
