【摘要】 以某型涡扇发动机及其主燃油系统液压机械式调节器为研究对象，在对发动机调节规律进行分析的基础上，建立了转速控制系统、加速控制系统的模型，以及温度传感器和温度放大器、叶片控制系统的元部件的模型。根据所建立的数学模型，利用ＭＡＴＬＡＢ中的仿真工具ＳＩＭＵＬＩＮＫ，对各系统进行了仿真，为发动机主燃油系统的进一步改进提供了理论基础更多还原

【Abstract】 A turbofan engine and its main fuel control system with hydromechanical regulator are studied.The rotational speed control system and the acceleration control system are modelled according to the analysis of the engine control program.The temperature sensor,temperature amplifier and blade control system are also modeled.According to thse mathematical models,all systems are simulated with the SIMULINK in toolbox of MATLAB.This work has important value for further research and improvement in the engine main fuel control system.更多还原
