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。数字仿真比较表明 :本文提供的发动机实时模拟器无论是稳态性能还是动态响应都能很好地反映出真实发动机的物理过程 ,可有效地应用于发动机数控系统研究中
In this paper, a single micro-computer (IBMPC / 2 86 + 80 2 87 coprocessor) for a type of biaxial afterburner turbojet engine real-time simulation study. After a proper special treatment of the characteristics of engine components and application of software design techniques such as 80 2 86 macro assembly and 80 2 87 floating-point parallel processing, the conflict between the calculation accuracy and the calculation speed in real-time digital simulation is well solved . The comparison of digital simulation shows that the real-time engine simulator provided in this paper can reflect the physical process of real engine both in steady-state performance and dynamic response and can be effectively used in the research of engine numerical control system
