  • 헬리콥터와 같이 비행 중 고장 또는 작동 불능 시 대처가 용이하지 않고 대형의 참사로 이어지는 비행체에 대해서는 안전이 최우선으로 고려되어야 한다. 미국의 국가교통안전위원회에서는 1963년부터 1997년까지 34년간 민간부문의 회전익기의 사고를 조사하여 분석한 바 있다. 본 논문은 터빈엔진 헬리콥터의 사고 동향을 파악하여 헬리콥터 안전 운항에 기여하고, 또한 한국형 중형 민수헬기를 개발하기에 앞서 주요 설계요소를 고려하기 위하여 NTSB에서 미국의 민수용 단발 및 쌍발 터빈 엔진 헬리콥터 사고에 대하여 유형별로 집계, 조사한 결과를 인용하여 전반적인 사고 경향, 사고 유형 또는 원인, 활동별, 운용 단계 별에 사고에 대하여 심층적으로 비교, 분석하였다.

  • This paper presents development activities of the T700/701K turbo-shaft engine for Korean Utility Helicopter(KUH). The T700/701K is the first rear-drive variant of the GE's T700 engine which is proven for military applications in the world. The main workscope of the development includes a modification from a front-drive engine to a rear-drive one, an performance enhancement of the power turbine and an incorporation of two channel FADEC(Full Authority Digital Engine Control) system for more reliable operation. The first engine run for development and qualification test was successfully completed in 2008. Since the PFRT(Preliminary Flight Rating Test) has been completed, the first flight of the engine installed in the first prototype of KUH has been successfully demonstrated in March, 2010 and the engine installation compatibility tests are being carried out during KUH flight test. The test and evaluation for qualification has been done except for the low cycle fatigue test up to date.

  • This paper presents qualification process of the T700/701K turbo-shaft engine for Korean Utility Helicopter(KUH). The T700/701K is the rear-drive variant of the GE's T700-701C/D engine which was qualified for military applications in the world. The main scope of the development is the modification from a front-drive engine to a rear-drive one, the performance enhancement of the power turbine and the incorporation of two channel FADEC(Full Authority Digital Engine Control) system for more reliable operation. Therefore, T700/701K engine must be qualified by Korean government in order to perform a flight in the country. Reflecting the influence of developing scope, the main requirements including performance and control are verified by test and analysis, while the requirement for module or component that is same to that of T700-701C/D are verified by similarity.
