Performance optimization for refueling pumps
摘要
Abstract
For a particular air refueling power system model which consists of RAT and a centrifugal fuel pump,on the premise of maintaining constant RAT,using the hydraulic design to optimize the performance of the refueling pump,thus the development needs of the system as a whole to improve the output power was satisfied.Firstly,using CFD method,the refueling pump was redesigned to optimize the performance.Full three-dimensional numerical simulation is applied to the optimized model.After repeatedly iterative optimization processes,the final optimized design was finally obtained.Secondly,based on optimization results,specimen products were made and tests were performed to verify the design.The comparison of test data and simulation results shows that,after cycling optimization procedure of theoretical design,numerical simulation and theoretical redesign,the optimized pump's performance is superior to that of the original one.The analysis of the internal flow shows that the vortexes in the optimized flow domain are smaller and weaker.Compared with the original one,the optimized pump's efficiency is increased by 8％,and the pumping pressure is raised by 10％.The results of this study can help enhance the reliability of system operation and solve the matching problem of the system and provide reference for optimal designing of other air-fuel pumps.关键词
