Abstract

발사체(50)는 공기 중의 한 위치로부터 공기/물 경계면을 통해 수중 물체(24)를 향해 발사된다. 발사체(50)는 총신(22)내로 직접 수용되어 이로부터 발사되는 전 구경의 것이다. 총(22)의 보어와 접촉하는 발사체(50)의 부분은 발사시 총의 보어를 부당하게 손상시키지 않거나 보어로 전이되지 않는 재료로 제조된다. 발사체(50)는 물 내에서 발사체(50) 둘레에서 캐비테이션 공간(30)을 형성하는 전방 단부 스팅어 헤드(74)를 포함하여, 발사체(50)의 나머지 부분에서의 물 항력을 최소화한다. 발사체(50)는 발사체가 물을 통과할 때 캐비테이션 공간(30)의 벽 내로 흔들리는 경우에 캐비테이션 공간(30)의 측면과 접촉하는 견부(90)를 포함하여 발사체(50)가 전도되는 것을 방지하는 복원력을 생성한다.The projectile 50 is fired at a location in the air through the air / water interface toward the underwater object 24. Projectile 50 is of a full diameter that is received directly from gun barrel 22 and fired therefrom. The portion of the projectile 50 that is in contact with the bore of the gun 22 is made of a material that does not unduly damage the bore of the gun or transition to the bore at launch. Projectile 50 includes a front end stinger head 74 that forms a cavitation space 30 in the water around projectile 50 to minimize water drag in the remainder of projectile 50. The projectile 50 includes a shoulder portion 90 that contacts the side surface of the cavitation space 30 when the projectile swings into the wall of the cavitation space 30 as it passes through the water to prevent the projectile 50 from being conducted Generate restoring force.
