航空发动机实时并行仿真器设计及应用

The Design and Application of Real Time Parallel Simulator for Aeroengines

给出了利用 8个数字信号处理 ( DSP)微处理器 ( TMS32 0 - C30 )设计航空发动机数字仿真器的原理及结构 ,讨论了基于多口存贮器设计共享存贮器的性能特点。在以 PC机为主控机构成的主 /从仿真器系统上运行了某型发动机仿真模型 ,给出了仿真模型在该仿真器上运行的任务分配方法 。

By using 8 Digital Signal Processing (DSP) microprocessors, the principle and structure for designing an aeroengine digital simulator are presented. Based on a multi port memory, a common shared memory is designed and its characteristics are discussed. An aeroengine simulation model is executed on the master/slave simulator system controlled by a PC computer, and the task assignment method is given. The time of computing the model by one processor is compared with the time by two processors.
