Definitions

  • the invention relates to a projectile according to the preamble of claim 1, in which often a high dead load portion of an increase in performance sets narrow limits.
  • the invention is based on the object of reducing the dead load component in a projectile of the aforementioned type.
  • DE-PS 14 28 679 which is a hard core projectile to combat Tank targets concerned. It forms damping intermediate layers of low sound hardness and thereby disadvantageously reduces an average effective density of the flight floor in question.
  • the reduction in the dead load portion advantageously combines an improved permeability to electromagnetic radiation.
  • the teaching in the characterizing part of patent claim 10 is finally directed to a safe removal of the carrier floor in question.
  • the spherical containers with different properties for example diameter, density, etc.
  • these methods include: sieving, current classification, wind sifting, flotation, centrifuging and magnetic separation.
  • a wing-stabilized lower-caliber projectile 10 according to FIG. 1 has a sabot 12 consisting of a plurality of segments, which are not identified in any more detail.
  • the segments are essentially made of a composite material which has hollow spheres made of glass and / or quartz held together by a matrix, the shell material of which each forms an individual phase.
  • the extremely low density of the composite material in question results in a very low dead load component of the floor arrangement shown.
  • Means for mutual positive locking between the floor 10 and the sabot 12 are arranged. The form fit is given in the tube during the projectile pass. After leaving the pipe, the segments detach themselves from floor 10 and fall to the ground.
  • the low density of the composite material used in addition to an increase in the performance of floor 10, also proves to be advantageous: the segments have only a very short range, and this largely precludes any danger to own troops in the vicinity of the firing position.
  • the weight saving there is a further advantage through the extensive replacement of a usually metallic material by the composite material in lower costs for material and production and in a saving of higher quality material and a protection of its occurrence.
  • both a guide hood 16 and a moving floor 18 are advantageously made completely or largely from the composite material.
  • the advantages resulting from this have already been described in connection with the exemplary embodiment according to FIG. 1.
  • a guided missile 32 according to FIG. 3 has a seeker head 34 with a tip-side cladding 36.
  • the latter is made of the composite material having hollow glass spheres, which advantageously not only has a low density for reducing the dead load component and an increase in performance, but is also characterized by a high permeability to electromagnetic radiation.
  • a wing-stabilized full-caliber projectile 22 according to FIG. 4 has a spacer 24 on the tip side for an igniter 26 and a tail unit carrier 28 for a stabilizing tail unit 30.
  • the tail boom 28 can be designed to be very long in order to achieve a favorable stabilizing tilting moment and at the same time reducing the dead load component.
  • a production of the tip-side spacer 24 gives, in addition to the reduction in the dead load component, the further advantage that a spike formed from a shaped charge insert 25 is disturbed considerably less by the composite material than by metallic material in previously common designs.
  • the hollow spheres of the composite material can be designed as containers for active substances.
  • the active substance is released when the spherical shell breaks due to impact or the detonation effect of an explosive or fragmentation charge.
  • a projectile according to FIG. 3 can advantageously serve other purposes in addition to shaped charge and explosive effects.
  • the active ingredient can either be used for target marking (for example colored smoke) or to support the above-mentioned effects, for example by additional fire, glare or irritation effects, in the latter example there are balls filled with HCI in addition to balls filled with Ti Cl 4 are.
  • a projectile according to the invention can also be predominantly or exclusively designed as a payload carrier using the composite material.
  • Goods for supply e.g. food, medication and necessary aids
  • for rescue e.g. life jackets, metal-coated foils and signaling devices
  • the composite material is advantageously used for parts which have to withstand predominantly pressure loads. If other types of stress occur, for example tension, the composite material can have fiber reinforcements in the relevant areas.
  • form-locking means for absorbing the high shear forces in the area of the drive-cage side can contain reinforcements running transversely to the longitudinal axis of the projectile, or be made entirely of metallic material which is enclosed on the outside by the composite material.
  • Thermoplastic e.g. epoxy resins
  • thermoplastic e.g. polyethylene
