Title (EN) WARHEAD HAVING IMPROVED EFFECTIVE RANGE
(FR) TÊTE EXPLOSIVE AYANT UNE PLAGE EFFICACE AMÉLIORÉE
(KO) 유효 사거리가 향상된 탄두
Abstract:
(EN) The present invention relates to a warhead having an improved effective range, comprising: a hemispherical front end portion (10); a concave portion (20) connected to a rear end of the front end portion (10) and having a curved surface concaved inward; an inclined portion (30) connected to a rear end of the concave portion (20) and slantly formed a predetermined angle (A) with respect to the horizontal line; a step portion (40) connected to a rear end of the inclined portion (30) and slantly formed a predetermined angle (A') with respect to the horizontal line; and three fluid guiding grooves (50) formed over a rear edge and a rear end surface of the warhead. When the warhead passes through water, the configuration of the present invention can further effectively generate and long maintain a supercavitation state, thereby greatly improving an effective range of the warhead.
(FR) La présente invention se rapporte à une tête explosive ayant une plage efficace améliorée, comprenant : une partie d'extrémité avant hémisphérique (10) ; une partie concave (20) reliée à une extrémité arrière de la partie d'extrémité avant (10) et ayant une surface incurvée concave vers l'intérieur ; une partie inclinée (30) reliée à une extrémité arrière de la partie concave (20) et formant de façon inclinée un angle prédéterminé (A) par rapport à la ligne horizontale ; une partie en surépaisseur (40) reliée à une extrémité arrière de la partie inclinée (30) et formant de façon inclinée un angle prédéterminé (A') par rapport à la ligne horizontale ; et trois rainures de guidage de fluide (50) formées sur un bord arrière et une surface d'extrémité arrière de la tête explosive. Lorsque la tête explosive passe à travers de l'eau, la configuration de la présente invention peut en outre générer et maintenir de manière efficace et longtemps un état de supercavitation, ce qui permet d'améliorer considérablement une plage efficace de la tête explosive.
(KO) 본 발명은 유효사거리가 향상된 탄두에 관한 것으로, 반구 형상의 선단부(10)와; 상기 선단부(10)의 후단과 연결되면서 내측으로 오목한 곡면을 가지는 오목부(20)와; 상기 오목부(20)의 후단과 연결되면서 수평선을 기준으로 일정 각도(A)로 경사지게 형성되는 경사부(30)와; 상기 경사부(30)의 후단과 연결되면서 수평선을 기준으로 일정 각도(A')로 경사지게 형성되는 단턱부(40) 및; 상기 탄두의 후미 및 후단면에 걸쳐 형성되는 3개의 유체유도홈(50);으로 이루어지는 것을 특징으로 하며, 이러한 구성에 의해 본 발명은 탄두가 수중을 통과할 때 초공동 현상이 더욱 효과적으로 생성되면서 오랫동안 유지됨으로써 탄두의 유효 사거리가 대폭 향상된다.
