Title: METHOD AND ASSEMBLY FOR MEASURING A GAS TEMPERATURE DISTRIBUTION IN A COMBUSTION CHAMBER
Abstract:
An optical sensor (C) directed into a combustion chamber (BK) is used to selectively sense a predefined spectral range of an optical spectrum for different light paths (LW) running through the combustion chamber (BK) to measure a gas temperature distribution in the combustion chamber (BK). A spectral intensity (SI) is determined for each spectral range and associated with an item of light path information (LA) which identifies the light path (LW) in question. The spectral intensities (SI) determined and the associated items of light path information (LA) are fed as input data to a machine learning routine (NN) which is trained to reproduce spatially resolved training temperature distributions (TTD). Output data from the machine learning routine (NN) are then output as the gas temperature distribution (GTD).
