A STUDY OF ENGINE SIMULATION METHODS FOR OPERATION FLIGHT TRAINERS (PHASEⅡ REPORT)

摘要

The second phase of an investigation to determine optimum equations to be used in engine simulators for operational flight trainers has resulted in the development of theoretical equations which describe the operation of the compressor, turbine, burner, and other engine components. A plot of the compressor equations definitely resembles that of a conventional compressor map. The study supports the con¬clusion that, with further simplification and development, theoretical equations which are suitable for engine simulation purposes can be derived. In addition to the theoretical investigation, a program of simulator design by curve-fitting techniques applied to performance data for the J79-GE-2 engine has been started. A method for analog computation of the product terms which arise in the function-factoring process for the design of function generators has been developed. An example tested on the analog computer gave excellent results.
