Abstract : The primary objective of this study contract is to develop practical techniques for the digital simulation of turbine engines and the associated controls. Detailed simulations of typical control components were developed and verified by comparison with actual test data. The general development of several potential engine controls is then presented and critical areas of concern are discussed. These controls were simulated for two complex engine simulations to document these areas of concern and to demonstrate the feasibility of the digital simulation techniques. A comparison of several modes of control or control implementations is presented for each engine. Studies were completed in the areas of automatic assessment by utilization of the digital computer and manipulation of control variables to optimize the performance of a specific system. Such as assessment and optimization would be useful in comparing several systems. Finally, a summary of the engine characteristics is included in addition to the program organization and simulation concepts which have been derived. This study demonstrated that practical digital simulation techniques can be developed and applied to complex turbine engines and controls. (Author)
