Definitions

  • projectiles of extended length present certain advantages in that their zone of dispersion on fragmentation is a maximum, owing to the rearward protrusion from the ground of the main portion of the detonating charge, at the moment of impact. In this manner the localizing influence on the effect of detonation, due to irregularities in the ground is to a great extent overcome.
  • a projectile of such shape that the chamber pressure in the gun may be applied to a substantially large surface thereof, thus obviating the rearward thickening ofv the projectile walls customary in a projectile of normal design.
  • Another object of my invention is to provide a projectile adapted to be fired effectively under wide variations in the angle of elevation, without relying on its rotation about its axis to retain its position along the trajectory.
  • I provide a projectile, substantially non-rotatable about its axis, having the known advantages of a forwardly placed center of gravity and corrective wind vanes, but by tapering the body of the projectile rearwardly and also providing centering means at the rear of said tapered body, I efiect a gradual release of gas pressure, while continuing to guide or center my projectile until said release has been substantially effected.
  • I am able to obtain accurate and effective firing even at high angles of elevation, and substantially reduce the depth of dispersion usual in ordnance of this type.
  • a further object of my invention is to provide a projectile, the firing of which from the gun will not be disclosed by a highly luminous flash; similarly I aim to reduce the report emitted on gun fire so that the exact position of the battery shall not be disclosed to the enemy.
  • a further object of my invention is to secure even fragmentation of the projectile walls on detonation of the charge and their projection or dispersion at high velocity over a wide area.
  • Fig. 1 of the drawing I show a projectile consisting of ashort ogival head A, adapted to receive an impact fuse Bqf known design, andhaving a cavity C to belfille d with a high explosive.
