A New Positioning Method of Multichannel Pyrometer in Aeroengine

We propose a novel framework for optimized evaluation to address the challenging problem in aeroengine such as the positioning of the pyrometer featured with multichannel. Using COMSOL Multiphysics in combination with MATLAB, we have implemented the turbine blade radiometric temperature scanning area positioning, pyrometer temperature measurement target resolution analysis, and multichannel pyrometer positioning and evaluation through the careful selection of evaluation indexes. The overall performance of the proposed framework as well as the effectiveness of each function were evaluated through experimental cases. After positioning and installing the pyrometer in this way, it will exert its optimal temperature measurement performance. This approach will guide the development direction of pyrometer positioning research in the future.
