Abstract

A cruise missile uses wings and a jet engine like an airplane to reach the target after cruising a considerable distance. An integrated design of a cruise missile based on radar cross section (RCS) reduction and enhanced aerodynamic performance is indispensable, since it must be able to fly long-distance at subsonic speed without being detected by enemy radar. In this study, we designed a Taurus-type cruise missile and analyzed its RCS and aerodynamic characteristics using the physical optics (PO) technique and the Navier-Stokes CFD code. As a result, we obtained the optimal shape of cruise missile with improved aerodynamic performance and reduced RCS.

순항 유도탄은 비행기처럼 날개와 제트엔진을 사용하여 상당 거리를 순항한 후 최종 목표에 도달하는 유도탄이다. 적의 레이더에 쉽게 포착되지 않을뿐더러 아음속 장거리 순항이 가능해야 하므로, RCS 저감과 향상된 공력성능을 고려한 통합 설계가 필수적이다. 본 연구에서는 Taurus 유도탄과 유사한 순항 유도탄 모델을 설계한 후, Physical Optics (PO; 물리적 광학) 기법과 Navier-Stokes CFD 코드를 사용하여 비행체의 RCS와 공력특성을 분석하였다. 이를 바탕으로 공력성능 향상과 RCS 저감 기술이 적용된 순항 유도탄의 최적 형상을 도출하였다.
