Abstract

In this paper, design and simulation of fuel control unit (FCU) for a widespread turbojet engine is presented. For this purpose, a brief review on importance of control strategy and engine control modes is firstly presented. Next, the steady state and transient modeling flowchart for the engine is explained and a dynamic model for prediction of engine behavior is developed based on the described flowchart. Then, In order to confirm the ability and effectiveness of the used approaches, the engine simulation results are compared with the experimental results and the good agreement between them illustrates the effectiveness of the steady state and transient modeling. After that, the designed strategy for the engine fuel control unit is described in details and the mathematical equations of FCU parts are presented. Moreover, the mathematical modeling is used for development of a simulation model in SimHydraulic software and the FCU behavior is studied using the developed model. Finally, integration between engine and FCU simulation is done and the simulation results are presented in order to confirm the design and simulation process. The proposed design in this paper can be used for other similar case studies as a regular approach.
