Abstract

Background: A centrifugal vane pump driven by a three-phase AC motor is a key component for modern equipment. Therefore, its condition directly affects the operating and safety performance of the system. Modeling and simulation are effective methods for the system analysis. Methods: A mathematical model of a Tank-to-Engine Fuel Feed System (T-EFFS) is designed based on its phased-mission behavior and structure redundancy. Both of the damage modes that arise frequently in a given type of system are tracked: the fuel feed pump seal damage due to fatigue and the vane damage due to corrosion. Then, a multiple degradation T-EFFS model is established to simulate the fuel pressure at the system outlet under different damage modes. The morphological spectrum decrement index is used to describe the damage of the system. Results: The results show that the T-EFFS model can describe the phased-mission behavior of the system and meet the requirement of the fuel flow rate for the entire mission profile. Then, the decrease in the fuel pressure of the T-EFFS with the cumulative effects of vane damage and crack growth under different behavior modes is simulated along its life span. Conclusion: This work aims to provide a model and data support for a subsequent investigation. The results can be used to fit the health background curve of the system, predict the performance degradation trend of the system at given life points, and further evaluate its remaining service life.
