PROPULSION SYSTEM MODELING AND INTEGRATED CONTROLS OPTIMIZATION.
Abstract
The demand for higher performance from turbo-propulsion systems has led to development of engines and inlets with more variable geometry features and more modes of operation. As a result the problems of designing suitable control systems have been greatly magnified. Engines and inlets with their individual controls are usually developed by different corporate entities and there have been very important obstacles to the development of compatible control systems which can provide for the maximum propulsion system capabilities. The course of action which was taken in this program was to develop mathematical computer programs and techniques which permit an early interchange between engine and inlet development organizations of comprehensive and precise dynamic performance characteristics of their respective systems. This course also permits more effective monitoring by the sponsoring Military agency. This report describes digital computer techniques, modeling structures, demonstration models and propulsion system disturbance functions which may be effectively used in controls systems development. Means for integrating engine and inlet dynamic controls functions are reviewed and a digital computer design optimizing program is applied to control gains adjustment of integrated propulsion system models for both turbojet and turbofan engines. New model techniques and structures are evaluated against available test data. (Author)
