The primary function of an aircraft fuel system is to provide a reliable fuel flow at a rate and pressure established for proper engine functioning for each operational condition and aircraft certification requirement. However, to provide fuel flow at a given pressure all sub-functions of the fuel system must work properly simultaneously and integrated as the pressure refueling, quantity gauging, control, and ventilation systems. The present work describes the model creation and simulation for aircraft fuel system during pressure refueling and single engine operation. Since the fuel system is composed of several subsystems highly integrated to each other, the proper functioning of the fuel system depends on this integration and a literature review was accomplished in order to raise the required information regarding sub-functions integration to create the model in LMS Amesim®. The LMS Amesim® model created to represent the existing correlations between each sub-system was simulated for pressure refueling and engine operations. Finally, the result of model simulation shows the functioning of the fuel system for normal operational conditions in conjunction with its sub-systems.
