Abstract EN
Fuel pump is a crucial component in aircraft engine ignition system.
For the hi-speed axial fuel pumps, rotating stall triggers vortex and affects the operation stability and security.
Sweep blade is widely used to solve the stability problems in aerodynamics field.
Investigation on the hydrodynamics was conducted in this study.
Based on the typical straight blade pump, positive and negative sweep blade pumps were modeled.
With the large eddy simulation method, CFD simulations were conducted to calculate and analyze the flow characteristics in the pump models.
To verify the simulation, experiments were also launched on the hydraulic test rig.
Results show that the vortex occurs at the suction surface of blade and gathers near the blade tip region.
Positive sweep blade is effective to reduce the hydraulic losses by driving the stalled fluid into the mid-part of blade.
By applying the positive sweep blade on the axial fuel pump, the instability operating region will be diminished.
Adopting sweep blade provides an effective means for stability and security of axial fuel pumps.
