The Study of Aerodynamic about High-speed projectiles using Fluid Structure Interaction analysis

유체 구조 연성 해석기법을 이용한 고속발사체에 미치는 공력의 수치해석적 연구

This paper is focusing on the define the safety of high speed projectiles from aerodynamic load. The Fin loaded from aerodynamic is the roll of high speed projectile's gide. The Fin can rotate about 25deg as maximum, and it has maximum aerodynamic load with 25deg position. For finite element analysis from aerodynamic load, fluid analysis will be conducted before structure analysis and export pressure data. The pressure data will be used as load condition at structure analysis of Fin. The result of structure analysis of Fin, there is some stress concentration and stress closed with yield stress of material. But this problem will be solved with change to another material.
