摘    要:
某型教练机在低空大表速飞行时,其发动机在最大状态下的供油量超过了发动机在各个状态的最大燃油流量软件值(GT=2300kg/h),发动机从主燃油流量控制转为发动机应急流燃油量控制。本文对发动机色行数据进行了深入分析,同时结合发动机的三大特性,对其控制系统软件进行更改,经过后续飞行验证.发动机燃油控制系统下作正常。

关 键 词:某型教练机发动机  低空大表速  燃油流量主控制系统  燃油应急控制

Abstract:
When a certain type trainer is flying in low altitude at high indicated speed, the pump delivery of engine at maximum region exceeds the software value of maximum fuel flow rate (GT=2300kg/h) at each status, the engine changes from main fuel flow control to engine emergency fuel flow rate control. The paper analyzes engine flight data deeply. It combines three characteristics of engine and makes change for the control system software. According to flight verification, the fuel control system of engine works normally.
Keywords:a certain type engine of trainer  low altitude and high indicated speed  main control system of fuel flow rate  fuel emergency control
