A method of definition for the adaptive simulation model of gas turbine performance

For overcoming some insufficiencies of adaptive simulation model of gas turbine performance at present, some reasonable solutions were proposed as follows: A reasonable choice of the modified coefficients according to measure parameters; a method of solving the modified coefficients without component maps; a polynomial fit of modified coefficients. The current adaptive simulation model of gas turbine performance was improved by using these solutions. Compared with experimental data, the computing results of two type turbojet engines indicated the solutions were feasible.
