Abstract

Abstract

A digital real time simulation by means of single micro computer has been developed for an actual two spool afferburning turbojet engine.In order to overcome the contradiction between the computation precision and the speed necessary to digital real time simulation technique,the characteristics of engine components have been reasonably simplified and modified and 80286 macro assembly,80287 float arithmetic parallel processing method and some programing techniques have been adopted.A non linear,large deviation digital real time simulation has been obtained.The results of this simulation are comparaed with the measured data.It is shown that its calculation accuracy and speed are suitable for the real time simulation.
