Definitions

  • ABSTRACT [52] U.S. Cl. 89/12; 89/1 L [51] Int. Cl. F41d 7/04 A m ns is provided for remotely adjusting the align- [58] Field of Search 89/] L 41 A, 12, 13 126 ment or the boresighting of one or more barrels in a Gatling type gun. The adjustment may be variable and [56] Referen e Cited may be made before or during firing.
  • each barrel fires in sequence, from the same radial orientation as its fellow barrels, and is boresighted to a common target; and, therefore, dispersion is primarily a function of variation in barrel cluster angular velocity and barrel longitudinal rigidity.
  • a feature of this invention is the provision of a means for remotely adjusting the alignment or the boresighting of one or more barrels in a Gatling type gun.
  • the adjustment may be variable and may be made before or during firing.
  • FIG. I is a partial longitudinal view of the aft portion of a conventional Gatling type gun showing a control mechanism embodying this invention
  • FIG. 2 is a partial longitudinal view of the forward position of a conventional Gatling type gun showing a barrel alignment adjustment mechanism embodying this invention
  • FIG. 3 is a front view of the mechanism of FIG. 2;
  • FIG. 4 is a schematic of a tight dispersion pattern obtainable from the mechanism of FIG. 3;
  • FIG. 5 is a longitudinal view similar to FIG. 2, showing an intermediate adjustment of the alignment mechanisms
  • FIG. 6 is a front view of the mechanism of FIG. 5;
  • FIG. 7 is a schematic of an intermediate dispersion pattern obtainable from the mechanism of FIG. 5;
  • FIG. 8 is a longitudinal view similar to FIG. 2, showing an extreme adjustment of the alignment mechanism
  • FIG. 9 is a front view of the mechanism of FIG. 8;
  • FIG. I0 is a schematic of an extreme dispersion pattern obtainable from the mechanism of FIG. 8;
  • FIG. 11 is a longitudinal view of a modified barrel alignment adjustment mechanism embodying this invention'
  • FIG. 12 is a front view of the mechanism of FIG. II.
  • FIG. 13 is a schematic of the dispersion pattern ob tainable from the mechanism of FIG. 11.
  • this gun includes a receiver or rotor 10, having a cluster of gun barrels 12 fixed thereto, and journalled for rotation in a housing.
  • the housing includes a backplate 14 having an aft journal 16 for the rotor.
  • a tubular control assembly 20 is fixed to the housing and includes an aft tube 22, an intermediate tube 24, a collar 26, and a forward tube 28.
  • a motor 30, or other angular positioning means is fixed within and to the tube 24 and has power leads, not shown.
  • the stator of the motor is thus fixed to the housing.
  • the shaft 32 of the motor is coupled to an extension shaft 34 which is journalled at 36 to the tube 24 and extends forwardly through the tube 28.
  • a gear 38 is fixed to the shaft 34 and is meshed with and drives a gear 40 fixed to the shaft of a potentiometer 42, or other angular identification means, which has control leads, not shown.
  • a support plate 44 is clamped intermediately of the length of the barrel, advantageously to the conventional rings 46 which receive the conventional midlength clamp.
  • a central longitudinal tube is integral with the clamp.
  • a forward tube 50 is journalled within the tube by a pair of bearings 52 and 54 and is telescoped within, and longitudinally slidable with but rotationally fixed to the forward end of the tube 28.
  • the tube 50 has a threaded bore which receives the threaded midsection 56 of a rod or jack screw 58.
  • the aft end 60 of the rod 58 is longitudinally slidable with but rotationally fixed to the forward end of the shaft 34, so that rotation of the motor shaft 32 longitudinally advances or retracts the rod 58.
  • a spherical ring 60 is respectively fixed to the end of each gun barrel 12.
  • a muzzle clamp assembly 62 is disposed in the end of the cluster of gun barrels.
  • the clamp assembly has a plurality of bores 64 therein whose respective longitudinal axes are nonparallel to the longitudinal axis of the cluster of barrels.
  • the clamp assembly 62 is journalled on the rod 58 by a pair of bearings 66 and 68, but is clamped against relative longitudinal movement with respect to the rod by a pinned collar 70 and a nut 72.
  • each of the bores 64 diverges from the longitudinal axis of the cluster at a different angle. Relative longitudinal movement of the clamp assembly 62 will cause the respective bore 64 to cam the respective ring 60 to deflect the end of the respective gun barrel from the cluster longitudinal axis.
  • FIG. 3 the cluster is shown in its undistorted disposition provided by the clamp in its forwardmost position as shown in FIG. 2.
  • the conventional tight dispersion of shots is shown in FIG. 4.
  • FIG. 6 the cluster is shown in its mildly distorted disposition provided by the clamp in its midaft position as shown in FIG. 5.
  • the moderate dispersion with full central coverage of shots is shown in FIG. 7.
  • FIGv 9 the cluster is shown in its fully distorted disposition provided by the clamp in its aftmost position as shown in FIG. 8.
  • the large dispersion with an open center of shots is shown in FIG. 10.
  • the clamp 100 of FIGS. I1 and 12 should be utilized.
  • one bore 102 in the clamp has a longitudinal axis which is substantially parallel to the longitudinal axis of the cluster. That is, it is boresighted on the cluster axis at the conventional range in the conventional manner.
  • this particular barrel fills in the center of the pattern irrespective of the divergence of the remaining barrels.
  • a rotor having a longitudinal axis of rotation with respect to said housing and a plurality of gun barrels with respective gun bolts, each barrel respectively having an aft end fixed to said rotor in an annular row about said longitudinal axis of rotation;

  • adjustable means coupled to and between said housing and said driver for adjustably translating said driver relative to said housing.
  • said adjustable means includes:
  • a shaft which is adjustably extensible along said longitudinal axis of rotation.
