Definitions

  • This invention relates to spin-stabilized sub-caliber projectiles.
  • a projectile is frequently caused to spin about its longitudinal axis as it travels along its trajectory in order to maintain the projectile on its intended course. This spin is imparted to the projectile by the rifling in the barrel from which it is fired.
  • a projectile is sometimes fired from a barrel with a larger caliber than that of the projectile, for example the caliber of the projectile may be of the order of 75 percent of the caliber of the barrel.
  • the projectile is fitted with an annular device, commonly known as a sabot, which bridges the annular gap between the projectile and the barrel.
  • FIG. 8 is a sectional view along the line 8-8 of FIG. 7, and
  • the driving band 7 has an annular projection 10 which engages the rifling in the barrel from which the projectile is fired to cause spin to be imparted to the sabot 4.
  • the forward and rear sabots 4, 5 ensure that the projectile is correctly centered in the barrel.
  • thrust and spin are imparted to the projectile by the rear sabot 4, and the obturator 15 serves to reduce erosion of the barrel rifling by providing improved gas obturation.
  • the rear sabot 24 includes three equal angular segments 26 held in place on the base portion 23 by a driving band 27 encircling the segments 26.
  • the base portion 23 and segments 26 are formed with intermeshing buttress threads 26a.
  • the driving band 27 has a trapezoidal cross-section and is located partially within a correspondingly shaped recess 28 in the periphery of the segments 26. Also, the mutually engaging surfaces of the driving band 27 and segments 26 have intermeshing peripherally extending corrugations 29.
  • FIGS. 7 to 9 operates in a similar manner to that illustrated in FIGS. 1 to 6.
