Abstract

In this paper, aerodynamic characteristics of missile configuration with various grid fins in subsonic flow. To investigate the effects of grid fin shape, four types of experimental models were used. In addition, to examine aerodynamic characteristics of missile configurations with various grid fins according to effects of Reynolds numbers and configurations of grid fins, 6-components aerodynamic forces and moments were measured by internal balance in wind tunnel test.

본 논문에서는 아음속유동에서 그리드핀 유도무기의 공력특성을 실험적연구를 통하여 기술하였다. 그리드핀 형상에 의한 영향을 살펴보기 위해 폐쇄율을 달리한 그리드핀 형상모델을 이용하였다. 공기역학적특성을 살펴보기 위해 그리드핀 포함 유도무기 형상의 6성분 공기역학적 힘과 모멘트를 측정하여 레이놀즈수에 의한 영향, 그리드핀 형상에 의한 영향, 조종성능 등을 알아보았다.
