Abstract

Thermal and flow characteristics of the fuel system in an aircraft gas turbine engine were numerically studied by constructing a 1D network modeling. Using the commercial system analysis software AMESim, the fuel pumping unit and the fuel metering unit were modeled. The fuel-oil heat exchanger was also modeled to investigate the thermal effect of an oil system on the fuel temperature. The component modeling was verified by confirming whether the components work properly by examining the input signals and physical properties. Variations of properties with flight conditions were studied, then the shaft power and temperature were analyzed.

항공기용 가스터빈 엔진 연료시스템의 열 및 유동 특성을 해석하기 위해 1차원 네트워크 모델링을 수행하였다. 상용 시스템 해석 프로그램인 AMESim을 이용하여 연료의 승압을 위한 연료펌프 유닛 그리고 엔진 연소기로 유입되는 연료의 유량을 제어하는 연료조절장치의 구성요소를 모사하였으며, 오일 시스템의 열관리에 따른 온도 구현이 가능하도록 연료-오일 열교환기를 모사하였다. 구성요소의 모델링은 유입 신호 및 물성에 따른 구성요소의 정상 작동 여부를 확인함으로써 그 타당성을 검증하였다. 임무 조건에 따른 연료시스템의 물성 변화를 확인하였으며, 이에 따른 동력 및 온도 특성을 분석하였다.
