초록

현대의 항공기는 고성능이면서도 경량이다. 그래서 유연한 구조물의 특성이 나타나며 비행 성능에 영향을 미치거나 한계를 짓기도 한다. 이러한 유연 특성은 항공기 설계 초기 단계부터 분석이 필요한데, 이를 위해 유연 항공기의 동적·정적 거동을 분석할 수 있는 프로그램을 개발하였으며, 그 결과를 제시한다. 다물체 동역학 시뮬레이션 기법에 기반하여, 강체 비행 역학, 구조 진동 거동, 그리고 비정상 공기력 등을 세부 모듈로 개발하고 통합하였다. 마지막으로, 통합 시뮬레이션 프로그램을 이용하여 유연 특성 항공기의 등속 수평 비행과 선회비행을 분석하였다.

Modern aircraft are high-performance and lightweight. Thus, the characteristics of the flexible structure appear and affect flight performance or limit it. These flexible characteristics need to be analyzed from the early stages of aircraft design. To this end, a program to analyze the dynamic and static behavior of flexible aircraft has been developed and the results are presented. Based on the multi-body dynamics simulation technique, rigid flight mechanics, structural vibrating behavior, and unsteady aerodynamics have been developed and integrated. Lastly, the level flight and the turn flight of the flexible characteristic aircraft have been analyzed using this integrated simulation program.
