Real-time simulation of large aircraft fuel systems

摘要

This paper presents a method for the real-time simulation of the fluid-mechanical components of the fuel storage and transfer systems of large civil aircraft. The simulation includes modelling of fuel flow, fuel properties and related measurement sensors, under all regions of the aircraft’s flight envelope. The Fluid Network Model (FNM) has been successfully deployed in the core of several hardware-in-the-loop integration facilities for the testing of large transport aircraft avionics, including that of the Airbus A380. The principles, features, and limitations in pursuit of its real-time performance goal are presented, and qualitative test results are described to illustrate its application and utility.
