Definitions

  • the safety templates of most ranges do not allow the use of conventional ammunition in high-load curved shooting.
  • the range of this ammunition turns out to be too great.
  • a 155 mm shell with a hollow base fired from the 155 AU F1 cannon in charge 7 at the maximum range angle achieves a range of 23. 300 m.
  • shooting at smaller angles of elevation to reduce the range does not solve the problem posed by the safety jigs. Indeed, in this case we increase the risk of ricochet of the shell. In some cases, particularly unfavorable (very low angle, hard ground, ...)
  • Dimensions of the safety templates must be multiplied by a coefficient of up to 1.5 in order to avoid the risks arising from possible ricochets specific to a conventional shell.
  • the ammunition of instruction according to the invention is characterized in that it is constituted by a banal steel tube of low mechanical resistance of which only the external surface is machined so as to obtain in a single operation the projections, in particular the belt of necessarily that the ammunition must present.
  • the front part of the tube is closed and equipped with a jar containing a smoke-producing substance or composition which is destroyed by the impact on the ground of the munition.
  • FIGS. 1 and 3 are views in axial longitudinal section of ammunition according to the invention
  • FIG. 2 is a diagram comparing the trajectories of a conventional munition and of an ammunition according to the invention.
  • the body of the ammunition is constituted by a tube 1, open at its two ends in the example treated in FIG. 1.
  • This tube is made of ordinary steel with low mechanical characteristics. Only the outside of the tube is machined, the internal surface of the tube remaining raw.
  • the weak mechanical characteristics of the steel used make it possible to make the forcing belt 2 in the steel of the shell body, which leads to the elimination of the usual operations of machining the groove, knurling of the teeth, crimping of the belt, of the finishing machining of the crimped belt and of the control operations associated therewith.
  • the body of the wall can be produced at the lowest cost.
  • a closure 3 closes the tube near its anterior end on which is mounted a cylindrical pot 4 closed by a plug 5 and which contains a smoke-producing substance or composition 6.
  • this composition can consist of titanium tetrachloride forming, with the air humidity, a thick white smoke, upon impact on the ground of the ammunition, which causes the destruction of the pot under the effect of its compression between the closure 3 and the ground.
  • the constitution of the ammunition in the form of a closed tube only in the vicinity of its end allows the gases of the propellant charge to develop in a chamber of large volume, which entails, for a given propellant charge and a barrel , a decrease in the maximum pressure at the base (closure 3 of the ammunition), a decrease in the initial speed and a decrease in the range of the ammunition.
  • the general shape of the ammunition and the pot which equips it is such that it determines a very clear increase in the drag compared to that of the training ammunition currently used, from which result a notable decrease. of the range and an increase in the fall angle, therefore the decrease in the risk of ricochet.
  • the ammunition shown in FIG. 3 differs only from that of FIG. 1 by the fact that the body 1 and the closure 2 are in one piece obtained by any suitable means, advantageously by forging.
