X Type Turboshaft Engine Speed Servo System Modeling and Simulation

FU Qiang;School of Flight Technology,Civil Aviation Flight University of China;  
Based on X type turboshaft engine fuel regulator work characteristics,one of the important parts of speed servo system were modelecl and simulatel by analyzing its structure and working principle of thorough analysis,the dynamic,static condition the concrete mathematical model. In order to verify the correctness of the model,the speed servo system component model was built in the AMESim software. The simulation results show that,the speed servo piston can be very good with the top rod displacement and change,and the flapper nozzle flow area are basically the same,to meet the system performance requirements of turboshaft engine,the design has practical value.
