Definitions

  • the invention relates to a sub-caliber balancing projectile with a dismountable floor guide, the bore of which receives the balancing project in a form-fitting manner.
  • Bullet guides are used to fire sub-caliber, mostly armor-piercing bullets from a gun barrel of larger caliber in order to increase the penetration rate.
  • the projectile guide itself usually consists of a drive ring, in the cavity of which there is a projectile and on the casing of which there are guides which are referred to as sabots, sabots, drive pistons, drive disks, drive ring.
  • the floor guide is divided several times in the longitudinal direction and is released by the air forces after leaving the pipe. It transfers the high acceleration forces that occur during the launch to the actual projectile and guides it in the pipe. After leaving the pipe, the guide parts fall to the ground; they do not contribute to the effect at the target, but can endanger your own troops.
  • the sealing between the floor guide and the inner wall of the pipe against the accelerating propellant gases takes place by means of guide bands or guide rings, which consist of copper, sintered iron or, more recently, often also of plastic.
  • guide bands or guide rings consist of copper, sintered iron or, more recently, often also of plastic.
  • the guide parts should be as light as possible to facilitate the acceleration process in the tube and the detachment process. You also have to endure the high pressure and tensile loads during launch and in the acceleration phase.
  • the floor guides belonging to the state of the art are made of aluminum or magnesium alloys.
  • plastics are also used as guide material.
  • the weight ratio of the guide to the projectile is usually around 1: 1.
  • the invention has for its object to provide a projectile guide that can be produced inexpensively with high accuracy and has only a very low weight, whereby compressive strength and tensile strength are guaranteed.
  • the projectile guide is a pressed part made of hollow glass spheres with plastic binding material or glass binding material.
  • the projectile guides are molded articles made of very small hollow glass spheres, the specific weight of which is approximately 0.2 g / cm 3 and which are obtained as waste products, for example when burning coal dust in a fluidized bed process.
  • the hollow glass spheres have a diameter of approximately 25 ⁇ m to 1000 ⁇ m and are very inexpensive. By adding a little plastic adhesive or glass binding material as a percentage, the hollow glass spheres can be pressed as desired using known methods, and very pressure-resistant molded parts can be produced by curing or sintering.
  • foam glass or syntactic foams offers similar advantages.
  • the material mentioned can be filled in light metal.
  • a particular advantage is that bullet guides made of this material allow easy and quick separation from the bullet due to the large weight difference and can be broken down into very small and light individual pieces that do not pose a threat to your own troops.
  • Fig. 1 shows an arrow projectile 2, consisting of a bullet tip 4, shaft 6, wing end 8.
  • the largest diameter of the arrow projectile 2 is smaller than the inside diameter of the tube 9.
  • a projectile guide 10 is therefore required which has a cylindrical shape and has a bore 12.
  • Bore 12 can be wave-shaped or thread-shaped, so that it forms a positive and / or non-positive connection with a correspondingly designed jacket of the shaft 6. Both parts can also be designed in the manner of a spline or K-Profi.ls.
  • On the jacket 15 of the projectile guide 10 there are two guide bands 14 which ensure a gas and pressure-tight connection to the pipe.
  • the guide bands are preferably made of plastic, while the floor guide according to the invention a pressing member of hollow glass spheres with plastic binder material or glass bonding material, wherein the starting material commercial glass spheres of 25 / um to 1000 / um are.
  • the projectile guide 10 is divided several times in the longitudinal direction, so that after the arrow projectile has left the tube, it can detach from it and fall off as the projectile makes its way towards the target.
  • FIG. 2 shows a balancing projectile 20 which is accelerated by a sabot 22 made of Al material, which at the same time also transmits rotational forces to the projectile and which contains guide bands 24.
  • the projectile in the pipe is guided by a sabot 26, which is made of hollow glass material or by foaming and prevents the projectile from swinging in the pipe.
