초록

본 논문은 전방에 프로펠러를 장착한 수중발사체의 초기거동을 M&S(modeling & simulation) 기법을 활용하여 추정하였다. 수중발사체의 항력계수를 포함한 동체에 대한 유체력계수를 추정하였으며, 발사체의 추력에 대한 모델링을 수행하여 발사체의 동역학 모델을 구성하였다. 개발된 모델을 활용하여 발사체의 무게중심 위치와 발사속도의 변화가 초기거동에 미치는 영향을 분석하였다. 본 논문은 유사한 형상을 가지는 수중발사체의 초기거동 예측을 통해 수중발사체 설계 및 성능 예측에 기여할 수 있다.

Abstract

In this paper, the initial behavior of an underwater vehicle with ahead propeller was estimated by using modeling and simulation (M&S) technique. For the simulation of the vehicle dynamics, the hydrodynamic coefficients of the body, including the drag, were estimated. And the thrust generated by vehicle were also modeled to construct its dynamic model. Using the developed model, the effects of variations in the center of gravity and launch velocity on the initial behavior were analyzed. This study can contribute to the design and performance prediction of underwater vehicle with similar configurations.
