Abstract

The fuel pump, which is used for an aircraft, was first developed in Korea through the Civil-Military Dual Components Development Program. The BLDC motor type, which is superior to the DC brush motor when considering efficiency, endurance, and explosive environmental characteristics, was applied to the fuel pump given its capacity and operating condition. The magnetic flux of the permanent magnet was analyzed based on the magnet flux density equation, using the Maxwell equation and the environmental condition. The motor performance, according to the load, was analyzed using the finite element method in order to design validation. The motor assembly was developed by designing the motor drive and the EMI filters. The performance test results of the motor assembly for the fuel boost pump were consistent with the analysis.

항공기에서 사용되는 연료펌프를 민군겸용구성품개발사업을 통하여 국내 최초로, 국내 독자기술로 개발하였다. 연료승압펌프의 모터 조립체에 있어서 모터는 효율성, 내구성, 내폭발성 등의 관점에서 DC 브러시 모터보다 특성이 우수한 BLDC 형식을 채택하였다. Maxwell 방정식과 환경조건을 활용하고 자속밀도를 통하여 전자기해석을 수행하였다. 설계를 검증하기 위하여 유한요소법을 이용하여 부하에 따른 모터성능을 해석하였고 모터 드라이브와 EMI 필터를 설계하여 모터 조립체가 개발되었다. 연료승압펌프 모터 조립체의 성능시험 결과는 해석결과와 매우 일치하는 것으로 확인되었다.
