Research Project

Evaluation of the Condition of a Jet Engine through Exhaust Jet Analysis

To automatically assess the condition of the hot gas path in aircraft engines, the TFD uses the tomographic background oriented schlieren (BOS) method. This method relies on the fact that light rays deflect when passing through a field of gradients of the refractive index. The optical measurement equipment (measurement ring with a distinct dot pattern and several digital cameras) records this deflection as the distortion of said dot pattern. A tomographic reconstruction algorithm converts the distortion into information about the existing density field. Optical BOS measurements in the exhaust jet then allow for the pattern recognition and classification of different defects in the hot gas path of the engine by reconstructing the two-dimensional density field and applying a machine learning algorithm called support vector machine. Data obtained from experiments will be used to validate numerical simulations of possible defects in the hot gas path.
