Patent ID: 8082851

Claim:
A cavitating projectile, which comprises a head part conjugated with a secant nose surface along a cavitating edge, central part, and an aft part with a gliding surface, wherein a caliber of the projectile is defined by a maximum diameter of a circle describing a cross-section of the projectile, cross-section has a contour line enveloping said cross-section extending from the cavitating edge to the maximum diameter of a circle describing a cross-section of the projectile in a plane of an axial longitudinal section of the projectile is limited by the formula: D x =d×[ 1+( L x /d )×(2×sin φ/π) 1/N ] N , where D x is a diameter of the core line enveloping the cavitating edge; d is a diameter of the cavitating edge; L x is a distance from the cavitating edge to the maximum diameter of a circle describing a cross-section of the projectile; φ is an apex angle of tangents to the secant nose surface at points of conjugation of the secent nose surface with the cavitating edge measured from a side of the head part and φ is at least 60° to no more than 270°; N=is a core volume factor, wherein the caliber is equal to D x .
