• Component level models are frequently used to simulate the performance of gas turbines. Precision of these models are dependent on the performance map of the components, such as compressors, turbines and combustors. Difference between the simulation results and the field data can be ascribed to the deviation of the component maps. Shape similarities of component maps are observed so linear scaling factors can be used for correction. A method of adaptive modeling of gas turbine engine by scaling component map is discussed in this paper. The adapting method is composed by two nested parts. The inner part is a steady state model solved by matrix iteration algorithm. The outer part is a determination process of scaling factors solved also by matrix iteration algorithm. As a demonstrative example, a three spool gas turbine is simulated and its model is corrected by matching simulation results with field data.
