저자는 이전 두 편의 논문[1,2]을 통하여 미국과 유럽의 헬리콥터/회전익 개발에 대한 현황을 발표하였다. 그러나, 최근 세계적으로 진행되고 있는 차세대 회전익의 개발은, 이제까지 전통적으로 사용되었던 헬리콥터의 단점을 보완하는 새로운 형상(틸트 로터, 동축반전, 복합형)의 회전익 수직 이착륙기들이 나타나고 있다. 이러한 새로운 형상의 회전익 개발을 위해서는, 이제까지 전통적인 헬리콥터 개발에 사용되었던 기본개념설계/통합해석 프로그램을 한 단계 업그레이드한 새로운 설계/해석 프로그램이 필요하다. 미국과 유럽에서는 이미 반세기 이상 자체 축적되었던 기술 및 데이터 베이스를 이용하여 새로운 개발 프로그램들이 만들어지고 있다. 국내에서도 지난 20여 년간 헬리콥터와 다양한 형상의 회전익 개발이 이루어지면서 국내 연구진들에 의해 요소기술(공력, 구조해석 및 동역학, 비행역학, 소음해석 등 분야)들이 개발되었고 여전히 진행 중이다. 이들 개발된 요소기술들의 성숙도는 해외 선진국에 상응하는 정도이다. 본 논문에서는 미국/유럽에서 사용되고 있는 차세대 회전익 개발에 사용되는 기본개념설계/통합해석 프로그램들에 대한 장/단점들을 요약해 보고, 또한 앞에서 언급한 국내 연구진들에 의해 축적된 기술들에 대한 평가와, 이들을 통합하여 우리자체의 기본개념설계/통합해석 프로그램을 개발하는 가능성과 문제점들을 조사해 보았다.
The authors had presented two previous papers[1,2] on Helicopter/Rotorcraft develoment in Europe and US. Meanwhile, the next generation rotorcrafts, currently under development in US and Europe, have new configurations (tilt-rotor, coaxial, compound) of rotor-type vertical takeoff/landing rotorcraft...
