Abstract

This paper contains the process of investigating the cause of fuel filter contamination of P&WC's PT6A-67A engine. An outline of the fuel filter contamination and configuration of the fuel supply line are specified. The analytical methods were classified into fuel component analysis and solid sediment analysis(EDX, TGA, optical microscope). In summary, the sulfur was detected from fuel tank sealant as a major contamination component. As a follow-up, P&WC and the Agency for Defense Development will conduct engine fuel filter cycle checks and fuel tank cleaning for engine operation.

본 논문에서는 P&WC 사 PT6A-67A 엔진의 연료 필터 오염에 대한 원인 탐구를 수행했다. 관련하여 PT6A-67A 엔진 연료 필터 오염 개요와 엔진 공급라인 구성에 대해서 명시했다. 다음으로, 분석방법을 공급 연료 성분 분석과 고형 침전물 분석(EDX, TGA, 광학현미경)으로 분류하여 비교분석했다. 결과들을 종합하면, 검출된 주요 성분은 연료 탱크 실런트의 황 성분이었다. 이 결과들의 후속조치로서 P&WC와 국방과학연구소는 엔진 운용에 있어서 엔진 연료 필터 주기 점검 및 연료 탱크 세척을 수행할 예정이다.
