Abstract

Auxiliary Power Unit of FA-50 which provides energy other than propulsion is an important element to maintain airworthiness on aircraft. Also Inlet Guide Vane of Auxiliary Power Unit is a device that supplies appropriate airflow into the Auxiliary Power Unit after adjusting influent airflow into the load compressor. This report, based on the problems occurred the driving gears of Inlet Guide Vane, deals with cause of occurrence, troubleshooting, design improvement and result of test flight verification for FA-50 aircraft Auxiliary Power Unit lifespan.

FA-50 항공기 보조동력장치는 추력을 제외한 항공기의 동력을 생성하는 장치로 항공기 감항성 유지를 위해 매우 중요한 요소이다. 또한, 보조동력장치의 입구안내익은 로드압축기로 유입되는 공기 유량을 조절하여 적절한 공기량이 보조동력장치 내부로 공급되도록 유도하는 장치이다. 본 논문에서는 FA-50 항공기 보조동력장치 입구안내익 구동기어에서 발생한 문제점을 바탕으로, 발생원인, 고장탐구결과, 설계개선 내용을 기술하였으며, 개선된 연구에 대해 비행시험검증 결과를 함께 소개한다.
