Patent number: 10386164Abstract: The invention relates to small arms ammunition and can be used in the designs of projectiles intended for high precision long-range firing at supersonic and subsonic muzzle velocities of a projectile. A projectile of small arms ammunition comprises a head portion with a blunted nose surface, a central leading portion, and a boattail, which tapers towards the projectile base, wherein the largest diameter of the cross-section of the central leading portion is equal to “D”, the length of the head portion is equal to 1.9-2.9D, and the diameter at the interface between the nose surface and the lateral surface of the head portion is equal to 0.15-0.3D.Type: GrantFiled: August 26, 2015Date of Patent: August 20, 2019Assignee: DSG Technology ASInventor: Andrey Albertovich Polovnev

Patent number: 8464625Abstract: The invention relates to rifled and smoothbore firearms and can be used in barrel-mounted devices for firing in the air and in the water. The inventive barrel-mounted device for firearms comprises a unit for joining to the barrel, a cap and a starting part with gas vents. The starting part bore is the continuation of the barrel bore, and there are N?1 compartments formed between the casing and the starting part. Each compartment includes at least two gas vents and provides the possibility of gas exhaust from the starting part bore to the compartment through the first of the mentioned gas vents and gas exhaust from the compartment to the starting part bore through the second gas vent. The compartment length is 0.5-3.0 of the bore caliber and in the cross-section plane of the barrel-mounted device the minimal cross-section area of N?1 compartments, designed for the gas flow between gas vents, ranges within 0.4-4.5 of the barrel bore area.Type: GrantFiled: October 15, 2008Date of Patent: June 18, 2013Assignee: DSG Technology ASInventors: Andrey Albertovich Polovnev, Volodymyr Shaymukhametovich Khasiakhmetov

Patent number: 8082851Abstract: The invention relates to ammunition for missile weapon and firearm. The cavitating core of the invention comprises a head part conjugated with a secant nose surface along the cavitating edge, a central part, and an aft part with a gliding surface, wherein the caliber of the core is defined by the maximum diameter of the circle describing the core cross-section. The contour line enveloping the cross-sections from the cavitating edge to the core caliber in the plane of the core axial longitudinal section is limited by the dependence: Dx=d×[1+(1x/d)×(2×sin ?/?)1/N]N, where Dx—is the current diameter of the core enveloping contour R, mm; d—is the cavitating edge diameter, mm; Lx—is the current distance from the cavitating edge to the core caliber, mm; ?=60° . . . 270°— is the apex angle of the tangents to the secant nose surface at the points of its conjugation with the cavitating edge measured from the side of the head part; N=(2?/?)0.4 . . . (2?/?)0.Type: GrantFiled: February 12, 2007Date of Patent: December 27, 2011Assignee: DSG Technology ASInventors: Andrey Albertovich Polovnev, Vladimir Shaymukhametovich Khasiakhmetov

Patent number: 7942420Abstract: The invention relates to sports and entertaining facilities and in particular to aqua shooting ranges. The inventive aqua shooting range comprises a pool (1), an above-water fence, shooting positions (9) with weapons and underwater targets (5). The pool is provided with a transversal partition (6) separating the shooting positions (9) from the underwater targets (5). Each partition (6) is provided with a firing port (8). An additional shooting position (20) for shooting from an above-water position to water is embodied on the partition (6). The above-water part of the pool wall placed above the underwater target (5) and the above-water fence is provided with bullet stoppers (11). The shooting position is located in such a way that the weapon vertical guidance angle is limited to a value equal to or greater than 10 degrees with respect to the horizon. The invention makes it possible to increase the safety, learning, and training efficiency of shooting at underwater targets.Type: GrantFiled: May 3, 2006Date of Patent: May 17, 2011Assignee: DSG Technology ASInventors: Andrey Albertovich Polovnev, Volodymyr Shaymukhametovich Khaziakhmetov
