Abstract

In this study, the steady state performance analysis program was developed for a turboprop engine, and its performance was analyzed at uninstalled and installed conditions. For the purpose of evaluation the developed program was compared with the performance data provided by the engine manufacturer and analysis results of GASTURB8.0 program. It was confirmed that the developed program was reliable because the results by the developed program were well agreed with those by GASTURB8.0 within %%. The linear and non-linear GPA(Gas Path Analysis) programs for performance diagnotics were developed, and selection of optimal measurement variables was studied. Furthermore, in order to investigate effects of the number and the kind of measurement variables, the linear and non-linear GPAs were analyzed with various measurement set. If the measurement parameters were properly selected, the reliable and economic faults detection might be possible even thought the small number of measuring parameters were used.

본 연구에서는 터보프롭 엔진의 정상상태 성능해석 프로그램을 개발하고 비 장창 및 장착조건에서 성능이 해석되었다. 개발프로그램의 검증을 위해 GASTURB 8.0프로그램의 해석결과와 엔진 제작사의 주어진 성능자료를 비교하였다. 개발 프로그램은 GASTURB 8.0과의 비교 결과 5%내의 오차를 나타내어 프로그램의 신뢰성을 확인할 수 있었다. 성능진단을 위해 선형 및 비선형 GPA프로그램을 개발하였으며, 최적계측변수의 선정을 위한 연구를 수행하였다. 계측변수의 종류의 수가 진단의 정확성에 미치는 영향을 알아보기 위하여 선형 및 비선형 GPA프로그램은 다양한 변수를 이용하여 해석 되었다. 그 결고 적절하게 선택된 계측변수는 보다 적은 계측장비로도 신뢰성있고 경제적인 손상 탐지가 가능함을 확인하였다.
