23 March 1998 Contour and pattern recognition of temperature fields with image analysis

BMW Rolls-Royce is developing the civil turbofan engine family BR700 with a thrust range from 12.000 to 23.000 pounds. To improve the efficiency, life time and cycles of an engine it is necessary to know the wall temperature on its components. The distribution of turbine wall temperature is measured with so-called Thermal Paints, which change their color irreversibly according to the local maximum temperature. A CCD color line scan camera system to record and analyze these data is being developed. To understand the thermal distribution across the surface of a component, the paint color change boundary is identified and transformed into calibrated temperature data. This thermal distribution can be used to validate the engineering thermal model.
