摘要: 某小型涡扇发动机开展增大推力、提高使用高度的适应性改型工作.针对以往对原发动机燃油调节器部分所作的分析较少,使得改型工作缺乏必要的理论支持问题.主要分析了发动机燃油调节器的工作原理,建立系统稳态和加减速控制数学模型,并在此基础上对其高空适应性进行分析,最后提出相应的改进分析方法和具体措施.Abstract: In order to increase the thrust and flight adaptability of a small turbofan engine, the fuel flow regulator modification of original engine was required to provide theoretical support for modification.The operating principle of fuel flow regulator was mainly analyzed to establish a static and acceleration/deceleration control mathematical model, and then analyze the high-altitude adaptability.Finally, some modification methods and measures were recommended.
