Abstract:

The results of developing six alternate calculation procedures for parametric turbine engine performance computer programs is presented. The alternate procedures were evaluated separately and then collectively in a baseline parametric engine performance program. The alternate procedures dealt with thermodynamic properties, matrix coefficient prediction, regression of component characteristics, afterburner calculations and regression of the compression process. Analysis of the combined procedures resulted in a cost reduction of approximately 46 percent with average deviations in engine net thrust and fuel flow rate of less than 0.7 percent. Author
