A STUDY OF ENGINE SIMULATION METHODS FOR OPERATIONAL FLIGHT TRAINERS PHASE Ⅲ

摘要

The third phase of an investigation to determine optimum equations to be used in engine simulators for operational flight trainers has resulted in the development of unsealed d-c analog computer diagrams which are applicable to turbojet and turboprop engine simulations, These computer diagrams are based on simplified versions of the theoretical equations for engine components (compressors, "burners, etc.) which were developed during the second -phase of this investigation. The method of engine stimulation using these unsealed analog computer diagrams has been compared with current methods of engine simulation, and it has been found to be more flexible and more general than the other methods.nThis study recommends that a simulator of the design proposed in this report based on an existing engine should be constructed and tested; it also recommends that the operational flight trainer manufacturer be supplied with more detailed information on power plant operation including sets of steady-state data for the con¬dition of the gas at the input and output of each engine component and including component operating characteristics (component maps).
