Definitions

  • ABSTRACT Ammunition in which a generally teardrop shaped hollow projectile is formed of frangible plastic or other suitable material, the rear'end of the projectile is finned and the forward rounded or ogive shaped end is scored or grooved for ease of rupture on impact, the projectile carries a payload of a desired flowable material such as a liquid, powder, or a gas, and preferably a liquid, for dispersion on impact at target, the projectile is carried in a cartridge case in which ignitable propellant powder is disposed adjacent the rear end of the projectile and adjacent a primer, there being a blanket of soft resilient flexible polyurethane foam surrounding and behind the rear finned area of the projectile and disposed between the fins and the propellant powder to retain the powder in place in a compact zone adjacent the finned rear of the projectile.
  • a desired flowable material such as a liquid, powder, or a gas, and preferably a liquid, for dispersion on impact at target
  • the projectile is carried
  • This invention relates to ammunition having frangible filled projectiles which are projected to a target for rupture and dispersion of their filled charge on impact with a target.
  • the projectile has a special teardrop shape for minimizing turbulence, and has fins disposed along and about the tapered rear surface, with a resilient padding disposed about the tapered and finned rear surface to resiliently maintain desired positioning of the propellant powder in a compact zone adjacent the rear of the projectile.
  • FIG. 1 is a partial cutaway perspective view of a cartridge according to the invention.
  • FIG. 2 is a further fragmentary view of the illustrative cartridge, the cartridge case being shown in phantom for clarity of illustration of certain parts.
  • FIG. 3 is an exploded view of a projectile according to the invention and prior to assembly and filling.
  • FIG. 4 is a partially cutaway perspective view of the projectile of FIGS. 1 and 2 in assembled and filled form.
  • FIG. 5 is a perspective exploded view of the cartridge case after propellant loading, together with the projectile and powder retaining blanket or pad prior to assembly in the cartridge case.
  • FIGS. 6-10 are schematic views of successive assembly operations, and FIG. 11 is a further partial cutaway view of the completed cartridge.
  • cartridge 11 is adapted to be fired from a conventional smooth cylindrical bore percussion fire shotgun, and includes a case 21, a fin stabilized liquid filled projectile 31 frangible on target impact, a propellant powder charge 51, and a soft resilient blanket 41 disposed about and rearward of the rear finned area of the projectile 31.
  • Case 21 includes a cylindrical sheath which is preferably of a suitable plastic such as linear polyethylene, although such may be formed of any other suitable material such as a paper composition, etc.
  • Case 21 has a conventional rimmed brass cup base with a base wad 27, of suitable plyed paper, plastic, or composition construction, and a percussion primer 29, which may be of any conventional or desired construction for igniting the propellant powder charge 51 upon percussive firing ofthe primer 29.
  • Projectile 31 has a generally teardrop shape with a generally rounded nose section 33, a straight tapered rear section 35 and a finned rear section having fins 39 nested within blanket 41. Projectile 31 is retained in case 21 through retaining engagement of its forward nose end by annular in-rolled or crimped retaining lip 23a formed at the end of case sheath 23.
  • Projectile 31 has two sections 33 and 35 formed preferably of easily moldable thermoplastic materials such as nylon and polyethylene, and which are capable of withstanding the momentary high temperature burning of propellant powder charge 51 without melting or rupturing. Sections 33 and 35 are joined together along their annular shouldered interfitting junctions 33b, 330, 331', and 35b, 35c, 351, as by suitable bonding such as cement, spin-welding, etc., the rear end of the section 35 being initially formed with a fill tip 37 having a fill bore 370 and extending rearwardly of fins 39 for filling the projectile with a desired fiowable material, preferably a liquid, after uniting of the two sections 33 and 35.
  • a desired fiowable material preferably a liquid
  • the projectile is preferably incompletely filled to enable expansion on anticipated temperature rises above the ambient temperature existing during projectile sealing after filling; however, it is desirable that only the minimum requisite expansion space be left void within the projectile in order to maximize payload content.
  • the extent of liquid filling 32 is thus dependent upon the coefficient of thermal expansion of the liquid and any normally expected temperature rise thereof in use.
  • the projectile fill tip 37 is closed, as by melt sealing with a hot concave-ended iron, to form a hermetic closure 37b.
  • the projectile nose section 33 has suitable grooving formed therein, preferably radial V-grooves 33a radiating from the center of the nose section along the outer surface thereof. in order to achieve ease of multi-directional rupture of the nose section on target impact, and wide lateral dispersal and essentially aerosoling of the flowable liquid material 32 in the target impact zone. Grooves 33a also aid in holding the nose section 33 during spin-welding of the two sections 33, 35 together.
  • this target-impact-frangible liquid-filled projectile it is possible to fire through a glass window, including a conventional multilayered auto safety glass window, and effect dissemination of the liquid fill in a cloud of tiny liquid droplets within the target area beyond the window which may be perforated, as by being either partially or completely broken by the projectile, dependent upon the projectile velocity and glass strength.
  • a highly volatile liquid agent as the liquid fill 32, this target impact dispersal, whether against a wall, through a window or otherwise, is materially enhanced.
  • a liquid fill 32 of CS or CN liquid solution is effective in bringing about temporary disabling and control of persons from a substantial distance such as, for example, yards away from point of cartridge firing.
  • a suitable CS liquid solution may be formed of about I to 30% by weight of CS, and the remainder of methylene chloride or other suitable volatile liquid solvent.
  • the projectile 31 is provided with fins 39, which are canted in the range of about 1-5 degrees, preferably about 4 degrees, and formed in an air-foil shaped longitudinal sectional configuration.
  • the canting of fins 39 gives a rotational stabilizing motion to the projectile in flight and the air foil shape of the fins aids in this gyroscopic stabilization by the angularly directed air-foil lift forces as well as providing a low turbulence low drag surface for maximizing velocity, range, and accuracy.
  • the included taper angle formed by the outer tapered surface of rear section 35 should desirably be the maximum permissible while still providing the desired generally laminar flow therealong and past airfoil fins 39. This has been indicated to lie in the general range of about 20 degrees. It is for this reason of desired laminar flow, as well as the desire to accommodate a maximum payload of liquid fill that the preferred projectile configuration has a substantially straight tapered surfaced rear section 35; the straight taper enabling maximum internal volume with an included taper angle near the limit for laminar flow.
  • the nose section 33 is generally rounded for maximum payload holding capacity consistent with desired low wind resistance and maximum radial dispersal upon rupture on impact.
  • fins 39 be intact upon the projectile 31 leaving case 21; however, when formed of relatively easily frangible plastic material, such as nylon, these fins 39 may readily be ruptured or cracked if there should exist substantial quantitative unevenness of distribution of powder charge 51 in the areas between the fins 39.
  • blanket 41 of soft resilient elastic material such as polyurethane foam or polyethylene foam, etc., is disposed to extend about and behind the fins 39 and tapered rear surface area 35a therebetween.
  • Fins 39 are of a slightly smaller diameter than the internal diameter of case sheath 23, enabling the foam blanket 41 to be inserted into the cartridge case 21 by simple axial downward insertion of the projectile into the vertically upright case 21 as shown in FIGS.
  • the preferably square blanket configuration enables ease of accommodation of the blanket between the fins, and as will be noted from FIGS. 1, 9, and 11, the propellant powder charge is thereby gently but effectively retained essentially within a chamber bounded by the base wad 27, primer 29, case sheath 23 and soft elastic foam blanket 41.
  • the amount of powder charge 51 extending along the thin wall zone between blanket 41 and case sheath 23 is relatively small and maintained of sufficient quadrilateral evenness relative to its quantity as to obviate breakage of the quadrilaterally disposed fins 39 upon firing of the cartridge. It will be appreciated that the elastic resiliency of the blanket 41 will enable accommodation of various quantities of powder charge, while exerting a desired gentle resilient retaining action on the charge.
  • the case sheath 23 is inrolled or crimped as with a conventional end-rolling tool 71 while the case 21 is radially restrained by a guide cylinder 73, thereby completing the formation of the cartridge 11 to the final configuration of FIGS. 1 and 11.
