Document Type and Number:
WIPO Patent Application WO/2018/084391
Kind Code:
A1
Abstract:
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.
