| 摘 要： | 本文采用单一微型计算机 (IBMPC/ 2.86 + 80 2 87协处理器 )对某型双轴加力式涡喷发动机进行实时模拟研究。经过对发动机部件特性的适当特殊处理以及应用诸如 80 2 86宏汇编和80 2 87浮点运算并行处理等软件设计技巧,很好地解决了实时数字模拟时的计算精度与计算速度之间的矛盾。

| 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. |
