FIELD: rocketry.SUBSTANCE: invention relates to rocketry, in particular, to destructive agent case with opening stabiliser. Case comprises a cylindrical outer shell. Stabiliser is made as shields with crosswise arched stabilising surfaces. Said surfaces are fixed in the case on axes perpendicular to longitudinal axis of the agent case. Case is equipped with additional inner shell which is coaxially installed relative to outer shell. Maximum inner shell diameter is 0.60...0.85 of the outer shell inner diameter. Damaging agents are orderly arranged in the annular cavity formed by two shells. Stabilising surfaces of opening stabiliser are shifted to the front part of the case and fixed on axes. Distance from the front edges of the surfaces to the back part of the agent case is 0.2...0.5 of maximum case diameter. Length of stabilising surfaces is made in the range of 1.0...1.5 of maximum case diameter. Damaging agents can alternatively be made in the form of two separate fractions, differing from each other with geometric parameters. Fraction with larger sizes of damaging agents is located in the front part of destructive agent case.EFFECT: higher reliability due to reduced aerodynamic loads, higher efficiency, increased destructive effect, improved weight and dimension characteristics.1 cl, 1 dwg |
