FIELD: weapon. ^ SUBSTANCE: invention relates to ammunition. The shell contains a casing with a head section, warhead and sternmost section equipped with a device for increasing flying range and contained accumulation chamber and throttling device. The device for increasing flying range is equipped with a base ring and corrugated membrane, the outer edge of which is rigidly fixed on the base ring and the throttling device is disposed in the centre. The corrugated membrane is made with flute rings half laced with the following ratio of radial width of i-flute li to its mean diametre di dv: li/di dv=(1-K)/(1+0.67K), where K - coefficient characterising permissible irreversible deformation of the membrane material. ^ EFFECT: increase of shell flying range. ^ 2 dwg |
