초록

로터 블레이드의 구조변형을 포함한, 제자리 비행하는 로터 블레이드의 공력해석을 수행하였다. 와류포획능력을 향상시킨 전산유체 코드와 간단한 오일러-베르누이 보 모델에 기반을 둔 구조역학 방정식을 결합시켜 회전익 유동에 대한 연계 계산을 수행하였으며 계산결과 타당한 로터블레이드 구조변형 및 공력특성을 얻었다.

numerical study on the coupled fluid-structure for a rotor blade in hover was conducted. Computational fluid dynamics code with enhanced wake-capturing capability is coupled with a simple structural dynamics code based on Euler-Bernoulli's beam equation. The numerical results show a reasonable blade structural deformation and aerodynamic characteristics.
