Abstract

The rotor blade of helicopter is the core component determining helicopter performance and requiring low noise and low vibration because the blade becomes the major source of noise during flight. The performance analysis of candidates rotor blades is very critical because LCH(Light Civil Helicopter) will be developed parallel with LAH(Light Armed Helicopter) as an international upgrade program based on the existing platform of foreign civil helicopter. This research was aimed to recognize the performance of the candidates rotor blades compared with the newly developed foreign rotor blades and to investigate the feasibility about developing korea unique shape rotor blades by analysis the rotor performance and noise. The result of this research can be used for the target performance index during negotiation with foreign helicopter company and developing korea unique shape rotor blades.

헬리콥터 로터 블레이드는 헬리콥터의 성능을 좌우하는 동시에 비행 시 주된 소음을 발생함에 따라 고성능, 저소음 특성이 요구되는 구상품이다. 국내 소형무장헬기 개발과 병행하여 개발될 민수헬기는 해외체계업체 보유 민수헬기를 기반으로한 국제공동 업그레이드 개발이 추진됨에 따라 해외체계업체 제시 대상기종의 로터 블레이드 성능파악이 매우 중요하다. 본 연구는 해외체계업체 제시 대상기종 블레이드의 성능분석을 통하여 최신 해외 블레이드 대비 성능파악 및 국내고유형상 블레이드 개발 가능성을 타진하는 것을 목적으로 수행되었다. 본 연구의 결과는 일차적으로 향후 민수헬기개발사업의 해외협상 및 국내 고유형상 블레이드 개발 시 목표 성능지표 등으로 활용될 수 있다.
