Problems and Use of the Scaling Factors in the Numerical Simulation of Jet Engines Free

The possibility of the use of scaling factors in the calculations and in the simulation of gas turbine engines have been considered.

Application of this technique to the simulation of trend analysis, the evaluation of the component maps shifting during the operational life of the engine and the calculation of matrices of influence have been presented.

Moreover, some problems related to the use of scaling factors have been studied and their effects on the engine performance have been presented.
