Abstract (en)
[origin: EP0106411A2] 1. Small arms ammunition, comprising an axially symmetrical projectile (3 to 7; 12), a cartridge case (1) with a powder charge (2) and a primer (11) disposed centrally with respect to the longitudinal axis thereof, the cartridge case being secured in a portion (7) between the flattened tip (12) of the projectile and its rear end (6), characterized in that the profile of the projectile (3 to 7; 12 to 14) is defined by a summation function r(x) = r1 (x1 ) + r2 (x2 ) in which the range of x1 [is defined] by x1 = h/2(1-cos a)-s/2(1+cos a), in which h is an assumed length of x1 for a = pi up to a theoretical tip of the projectile (3 to 7; 12 to 14) and arc cos h-s/h+s =< a =< pi and the associated values of r1 are given by r1 = r0 2Root 1/pi (a-1/2 sin 2a) in which arc cos h-s/h+s =< a =< pi, and in which the range of x2 is defined by x2 > h in which r2 = const. = r0 , the theoretical tip of the projectile (3 to 7; 12) being remote by a distance (-s) from the zero point of a right-angled system of coordinates, the positive X-axis of which is an axis of symmetry and the Y-axis of which represents a direction of the radius r of the projectile and the actual tip (12) of the projectile (3 to 7; 12) is situated at the zero point of the system of coordinates (Fi. 2; Fig. 1).
