| 摘 要： | 在民用飞机防火系统地面模拟试验中，由于气流流量对试验具有重要的影响，因此，需要模拟发动机风扇舱、发动机核心舱、APU舱和货舱在飞行中的气流流量。由于流量的精度对试验结果具有重要的影响，设计一种基于PLC控制的气流模拟系统，基于PID控制算法，通过变频器控制电机带动风机模拟所需的气流，满足地面试验的要求。

| Abstract: | In the ground simulation test of fire protection system for civil aircraft,the amount of airflow in engine fan cabin, engine core cabin, APU cabin and cargo is needed to be simulated in flight as the airflow has an important impact on test. Due to the important influence of flow accuracy to test, a kind of airflow simulated system based on PLC control and PID control algorithm is designed. The draught fan drove by frequency converter controls motor simulated the need of airflow that meets the ground test requirements. |
