Analysis of modification and high-altitude adaptability for fuel flow regulator of a turbofan engine

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.
