Abstract : The primary objective of the study was to develop practical techniques for the digital simulation of turbine engines and controls. The first steps involved the definition of detailed control component simulations, verification of these simulations by comparison with test data, and deriving a workable model of a turbine engine. The report summarizes the investigations conducted to date in these areas. Detailed simulations of four typical control components in several control media were developed and a fifth component is partially complete. Good agreement between the responses of the simulation, analytical and initial test data verified the simulation approach. The control components were modeled in a generic simulation language, MIMIC. Two simulation models of a complex turbofan engine were developed, and reviews with the engine manufacturer indicated that these simulations do exhibit the proper characteristics. The engine was simulated in the generic language, MIMIC, and a specific FORTRAN program for the engine was developed. The principal advantage to the FORTRAN program is that computer time, which becomes quite long for an extensive program, is reduced by a significant factor when compared to the time required by the MIMIC engine simulation. The present studies indicate that a specific FORTRAN program is most economical for extensive simulations and should be used on the development of control system simulations and in defining system assessment and optimization features.
