Definitions

  • the present invention relates to a projectile with numerous applications, and more particularly to a hollow body applicable to explosive and non-explosive projectiles, dummy projectiles for practice or instruction,
  • the standard projectile according to the present invention fulfils these requirements completely, and also enables numerous advantages tobe obtained from the fact that,
  • a projectile is obtained which, when employed for example as a practice projectile, may be recovered after firing and be repeatedly employed immediately.
  • the fuse member is constructed in such a way that th. detonator may be placed, for preference, acing said zone, in order to eflect solely the rupture of the zoneof less resistance, more easily and instantaneously, for example in the case of w an instruction projectile with a charge of owder.
  • the instantaneous character and force of the deflagration cause the proj ectile according to the invention to break up completely into fragments, when employed as an explosive projectile, without the useful effect of the explosive being impaired by the zone of less resistance.
  • Fig. 1 is an axial section of the front portion of a projectile body according to the invention.
  • Figs. 2 to 8 are similar partial views of modified embodiments.
  • FIG. 1 denotes the wall of the body of the projectile (Fig. 1) which, in theexample shown, is of ogivo-cylindrical sha forward end, this body exhibits a zone of reduced resistance, owing to the provision of a recess 2, of any suitable form, in'the thickness of said wall.
  • the lower end of the fuse 3 carries the W detonator 4, which faces the recess 2 and is intended to ignite the charge (black powder, or other material) serving to indicate the spot where the projectile falls.
  • the projectile be filled with a suitable explosive.
  • the gases escaping from the broken section produce a cloud of smoke, whilst the front cone. of the projectile penetrates into the ground, under the effect of theacquired velocity.
  • the rear portion, or body, of the projectile remains intact and also enters the soil, after the cone, or remains in the immediate vicinity of the point of impact. Owing to its relatively large mass, it possesses sufficient vis viva to overcome the action of the powder gases tending to force it backward.
  • the smoke cloud produced enables the point of impact to be observed from a distance, under conditions of visibility approximately analogous to those of real firing:
  • the device according to the invention also offers the advantage of minimizing the risk of accidents where, through some fortuitous cause or inexpert handling, an obstacle unexpectedly situated near the piece and in the trajectory of the projectile, causes the fuse to act. In such case, the projectile will not burst, the rear walls offering sufficient resistance to the action of the charge, and it will simply break in the zone of less resistance, the' small fragments producedwhich are harmless by reason of their minute massbeing projected forward, in a cone of relative small base area, without risk of injuring th'eattendants by the gun.
  • the velocity of propagation and the violence of explosion are such that the projectile bursts, not only in the zone of less resistance, but simultaneously and normally throughout its length.
  • the zone of less resistance in the practice pro jectile is obtained by providing, in the forward portion of the body, a certain number of perforations, such as 5, 6, closed by plugs, such as 7, 8, of suitable material and disposed in such a way as to be ejected, on impact, by the action of the charge.
  • the perforations, such as 5, 6, may also be closed (Fig. 3) by removable thin, and therefore light, plates 9, of metal or other material, suitably enchased, riveted or otherwise secured on the body 1, and playing the same part as the plugs, 7, 8.
  • the projectile according to Fig. 4 comprises a body 11 provided with a zone of reduced resistance, constituted by perforations 12 closed by an inlaid piece 13 which fits against the adjacent portions of the body in such a way that the external contour of the projectile is the same as thatof an ordinary projectile.
  • the upper part 14 of the piece 13 is gripped between the body 11 and the neck 15. Its lower edgetightens a joint 16 consisting, for example, ofa copper Wire or a thread saturated with varnish, which renders the projectile perfectly staunch.
  • the piece 13 On impact, the piece 13 is torn off by the progressive thrust produced by the combustion of the charge (black powder), which then escapes through the perforations 12 and enables the point of impact to be gauged.
  • the body 11, or steel or other strong material, remains intact and can be recovered for future use with a replacement of 13 and a new fuse.
  • This construction offers, in particular, the advantage of simple and inexpensive manufacture.
  • the zone of reduced resistance is obtained by means of a casting 17, which is screwed on to the body 18 at 19, and on to which is screwed the neck 15.
  • FIG. 6 shows that still in accordance with the invention'the closure member 20 is extended in such a Way that it carries, at 21, the band of the projectile.
  • the projectile when used over again with a new piece 20, is always provided with a band the tightening components, 22, of which are always perfectly intact.
  • Figs. 7 and 8 show another construction, in which the zone "of reduced resistance is provided at the rear end of the projectile.
  • This zone may be constituted by providing, in the thickness of this wall, one or more recesses 31 (Fig. 7), internal cavities 32 (Fig.
  • the perforations 34 may also be covered; bythin plates, disposed inside or'outside the,
  • a jointing member or fitting of any. kind, 39 renders the projectile staunch.
  • the projectile doesnot function directly, it comes into con-j tact with the; surface ,ofthe ground, but only after a certain delay, during which its front portion will have embedded itself in theear-th.
  • a harmless practice projectile comprising a heavy externally cylindrical body portion and an'ogival nose at the front end thereof, a fuse carried by said nose having a detonator of limited charge insufficient to disrupt or bring said body to astandstill, the nose portion of the body being cut away opposite the detonator so that upon the detonation only parts of the ogival nose and fuse.
  • a harmless practice projectile comprising a hollow heavy body with a cylindrical body portion and an ogival nose at its front end, aifusecarried by said nose and closing the front of the'projectile, the nose portion of the 'body being weakened.
  • said fuse including a detonator of limited charge insufiicient to disrupt or bring said cylindrical portion to a standstill and supported opposite said weakened portion, whereby upon detonation the rupture of the body is confined to parts-0f said bodyand fuse severed from said cylindrical portion are projected forwardly in a cone of small apex angle upon disruption and said bod continues forward after the detonation so t at no parts of the projectile are thrown backward or laterally in event of a detonation adjacent the projectmg weapon.
  • a harmless practice projectile which may be recovered'and re-used, comprising a .hollow heavy body with an ogi'val nose at its front end, a fuse carried by said nose and vide passages through the body wall directed forwardly of planes transverse to the axis of the body, said fuse including a detonator of limited charge insuflicient to disrupt or bring said body to a standstill and supported opposite said inner ends of said passages, and
  • closures are of material of low density and light weight so that a small detonator charge is suflicient to project them from closing position.
  • a harmless practice projectile which may be recovered and re-used, comprising a heavy hollow body, a fuse having a detonator of limited charge insuflicient to disrupt or bring said body to a standstill, and a disruptable and renewable mounting ring attached to said body and said fuse for connecting them fixedly together and forming a part of the front of the projectile, said fuse and body providing between them a forwardly and out wardly inclined passage through which the shock of detonation may operate upon the mounting ring to disrupt the latter, said inclination of the passage operating to cause the projection of the fuse and mounting ring forwardly upon disruption from the body within a cone of small apex angle, and whereby said body continues forward upon the det- 5 onation so that no parts of the projectile are thrown backward or laterally in event of a detonation adj acent the projecting weapon.
