차세대 회전익 항공기 기술동향 분석을 통한 발전방안 연구 = A Study on the Development Plan of Next Generation Rotary-Wing Aircraft Through Analysis of Technology Trends

다국어 초록 (Multilingual Abstract)

A rotary-wing aircraft is capable of vertical take-off, landing, and hovering. Due to its excellent low-velocity flight performance, it is widely used in civilian and military fields. However, the system characteristics have caused vibration and aerodynamic problems. As a result, flight performance has been limited. Recently, major advanced-technology countries have conducted various research and development to overcome the limitations of rotary-wing aircraft. Based on this, a new next-generation rotorcraft is being developed. Considering the domestic environment with many mountain areas, rotary-wing aircraft are essential systems. In addition, demand for next-generation rotary-wing aircraft has recently increased. Prior to the development of the next-generation rotary-wing aircraft, it is necessary to identify the technology to be developed. Therefore, in this paper, analysis of development in major advanced-technology countries and the status of domestic rotorcraft technology was performed.
A main component analysis was also performed. Based on this, core technologies for the next-generation rotary-wing aircraft are suggested. In addition, a future development plan and implications for rotary-wing aircraft are suggested through domestic and international development trends for each identified core technology.

회전익 항공기는 수직 이‧착륙, 제자리 및 전후좌우 비행이 가능하고 저속 비행 성능이 우수한 특성으로 인해민간, 군 분야를 막론하고 다양하게 활용되고 있는 체계이다. 하지만 주 로터, 꼬리 로터 등의 체계 본연의 특성으로인하여 진동 문제, 공기역학적 문제가 발생하였고 이로 인해 비행 성능에 한계가 있어왔다. 주요 선진국에서는 이러한회전익 항공기의 한계를 극복하기 위해 다양한 연구 개발을 수행하였으며 이를 기반으로 새로운 차세대 회전익 항공기를개발하고 있다. 산악 지역이 많은 국내 환경을 고려하면 회전익 항공기는 국내에 필수적인 체계로 최근 군에서는 차세대회전익 항공기에 대한 소요가 제기되었다. 이에 따라 본 논문에서는 차세대 회전익기 개발에 앞서 우선적으로 개발해야되는 기술을 식별하기 위해 주요 선진국에서 개발 중인 차세대 회전익 항공기 개발사례와 국내 회전익 개발현황을 조사하였고 주요 구성품 분석을 통해 차세대 회전익 항공기를 위한 주요 핵심기술을 제시하였다. 또한 식별된 기술별 국내‧ 외 개발현황을 통해 회전익 항공기 향후 발전방안과 시사점을 제시하였다.
