Abstract

The main purpose of this study is to compare the bird strike analysis result of the radome composed of composite laminate and sandwich structure attached to aircraft with test result. First of all, we generated bird model which has water properties through SPH(Smoothed Particle Hydrodynamics) method. And then bird strike analysis was conducted with initial velocity of bird measured from bird strike test. From analysis result we investigated whether structural failure occurred or not onto the radome and compare maximum displacement of the radome structure with test result. Also reliability of numerical analysis model was confirmed through time-dependent pressure trend on this collision process matched existing research result. Furthermore, we confirmed that failure behavior of the radome can be affected by density of the particles in the bird model.

본 논문의 목적은 항공기에 장착되는 복합재 라미네이트 및 샌드위치구조를 가지는 레이돔에 대한 조류충돌해석을 수행하고 해석결과와 시험결과를 비교 및 분석하기 위함이다. 먼저 SPH(Smoothed Particle Hydrodynamics)법을 통해 물의 특성을 가지는 조류를 모델링하였으며, 조류충돌시험을 통해 조류가 충돌할 때의 속도를 입력하여 조류충돌해석을 수행하였다. 해석결과를 통해 레이돔의 파손 여부를 조사하고 최대 변형량을 시험결과와 비교하였으며 충돌과정에서의 압력변화추이가 기 연구되었던 결과와 일치함을 확인하였고, 이를 통해 수치해석모델의 신뢰성을 확보하였다. 또한 조류모델을 이루는 입자의 밀도가 레이돔의 파손 형상에 영향을 미친다는 사실을 확인하였다.
