Aircraft fuel system simulation

It is noted that the design, development, and test of aerospace fuel and propellant systems is becoming a more complex problem. In particular, fuel and propellant systems are being asked to perform functions such as vehicle center of gravity control, thermal management, and damage control. These flight-critical functions, combined with the progress of new fuel system controllers toward an integrated utilities rack concept, have pushed these problems to a critical point. An integrated analysis and test environment is presented as a solution to these problems. The system includes a non-real-time analysis environment providing high-fidelity dynamic simulation of aerospace vehicle fluid flow pumping and tankage system. The system is applicable to both commercial and military aircraft and space vehicles, and provides a simulation of effects such as water hammer, cavitation, and multiphase. This analytic environment is then combined with a real-time simulation and emulation platform for a complete integrated approach to fuel and utility system analysis and test
