摘要
CFM56-3系列发动机是由美国通用电气公司(GE)和法国国营航空发动机研制公司(SNECMA)组成的国际公司(CFMI)研制生产的为波音B737-300/400/500型航空器翼吊发动机;其N2转速管理系统为飞机提供精确的燃油控制功能以防止发动机超速及失速情况的发生。N2转速管理系统主要通过接受发动机的核心转子转速(N2)和动力角(PLA)来控制燃油流量使发动机实际转速与目标转速相符。
The CFM56-3 series engine is designed for the Boeing B737-300/400/500 aircraft as wing hoisting engine by the CFMI.The N2 speed governing system provides the correct amount of fuel to the engine for operation under different operating conditions.It protects the engine from stalling or over speeding.The N2 speed governing system senses the physical core speed（N2） and the power lever angle（PLA） and adjusts the fuel flow that is necessary to maintain the desired speed setting established by the PLA.
