The Research of Aviation Variable Pump based on Frequency Conversion Technology

When the aircraft uses AC power supply, the traditional AC fuel pump cannot satisfy the requirement of exporting oil quantitatively. To solve the problem, the principle and the design process of aviation variable pump using AC frequency conversion technology is proposed. The variable pump is simulated and analyzed by CFD software and ideal performance curves have achieved and the simulated results have verified in practice. The results show that the performance of the variable pump has achieved the desired design goals and frequency conversion technology used in variable pump is feasible.
