Abstract:

Background: The centrifugal vane pump driven by three-phase AC motor is the key for modern equipments. So its health status affects the system operating performance and safety directly. Modeling and simulation is effective way for system analysis.

Methods: Based on the phased-mission feature in behavior and the redundancy design in structure, the mathematical model of tank-to-engine fuel feed system (T-EFFS) is obtained. Both damage modes arising frequently in the given type system are tracked, one is fuel feed pump seal damage due to fatigue, and the other is vane damage due to corrosion. Then multiple degradation T-EFFS model is established to simulate system outlet fuel pressure under different damage modes. And morphological spectrum decrement index is used to describe the system damage status.

Results: The results show that T-EFFS model can describe the phased-mission behavior of the system, and meet the requirement of the fuel flow rate for entire mission profile. Then fuel pressure dropping of T-EFFS with cumulative effect of vane damage and crack growth under different behavior modes are simulated along its life span.

Conclusion: The work is expected to provide model and data support for the subsequent investigate. It can be used to fit the system health background curve, predict the system performance degradation trend at some given life points, further evaluate the corresponding remaining useful life.
