Description

1 2514123

  The present invention relates to military charges acting

against targets in flight or on the ground.

  Missile defense or defense against very fast airplanes is becoming increasingly important and requires effective explosive charges up to passing distances, varying according to the project, of the order of a meter or

  a few meters, taking into account the guidance system used.

  This effectiveness must result in a very serious deterioration or

  destruction ("break") of the threat, capable of interrupting "instantaneous-

  In fact, a delay of a few seconds would lead to

  high braids involved, so that the opponent's mission is final-

  ment accomplished, despite partially destructive damage.

  To achieve the desired efficiency, the applicant has designed a new type of charge, particularly suited to a missile or a rocket, or an anti-missile or anti-aircraft projectile, which combines a blast effect and a

  perforating, cutting effect, acting at very high speed along long planes

  gitudinal, preferably passing along its longitudinal axis or along heli

  strings, more or less inclined with respect to this axis, such that, at a distance

  considered, the target cannot escape.

  Without departing from the scope of the invention, this charge can also be anti-aerodyne, anti-personnel, anti-tank and anti-concrete; for these applications, it can be provided with additional elements, specified below, falling within

  also in the context of the invention.

  According to the invention, the load comprises, at its periphery, longitudinal metallic coatings E whose concavity is oriented towards the outside, and

  each section of which rests on generators parallel to the longitudinal axis

  nal of the load or on helices with axes coinciding with the axis of the load, said section having, preferably and substantially, the shape of a V. These longitudinal coatings according to the invention are preferably

copper or tantalum.

  According to the invention, these coatings have a generally dihedral shape, and their angular opening is variable and adapted to the particular program of terminal effect sought For example, and without departing from the

  framework of the invention, it is indicated that this opening is preferably su-

  greater than 60, and may even be greater than 100.

  The longitudinal metal coatings according to the invention are suitable for

  seem to each other, for example (not limiting) by soldering, soldering, or by electronic bombardment They can also be produced directly by

deformation of a cylinder.

  The aerodynamic forces, such as steering moments, and the handling forces, are generally transmitted by the only coatings then serving as structure; however, this, if necessary, can be further reinforced by longitudinal members of resistant material, on which are

  fixed said coatings, for example by soldering, welding, gluing,

  weaving, etc. These coatings create the desired efficiency, producing effects

  dihedral hollow charge cutters.

  Furthermore, the effect of the V-shaped coatings according to the invention can be supplemented, according to the invention, by preformed flakes disposed at the periphery

  of the load, between said coatings.

  These preformed flakes provide a different charge efficiency

  by kinetic action, hence an additional anti-aerodyne and anti-

  personal In addition, and still according to the invention, these peripheral coatings

  V-shaped risks can also be supplemented by a cone before a hollow charge,

  whose (axial) effect is essentially anti-tank and anti-concrete.

  The charge according to the invention is initiated by one or two pyro-

  techniques and a column of explosive "crossing", preferably, the whole

length of the load.

  The main charge of the charge in hexos-based explosive

  lite or octolite is produced in such a way that there is a percentage in hexo-

  gene or octogen preferably greater than 80%.

preferably

  The Aylindric external profile of the load is protected by a

  swimming of low density and thickness According to a nonlimiting exemplary embodiment, this fairing is made of plastic material, preferably molded

or wound.

  According to the invention, the load can be made up of two half-loads placed one in front of the other, so that the orientation of their dihedrons (considered in a transverse plane) is staggered (offset by 1 / 2

  "not" of the dihedrons, of a 1/2 load compared to the other); it is so pos-

  either doubling the action distance, doubling the width or opening

  ture of the V-shaped coatings, for the same probability of reaching the target, ie to double this probability, at equal action distance This principle of shifting the half-charges can also be generalized, according to the invention we can have 3, 4 1/3 or 1/4 charges, and thus vary

  the opening of the V-shaped dihedrons, therefore the "step", the probability of reaching and

  terception, and the distance of action (destruction).

  As described above, the explosive charge according to the invention provides longitudinal cutting perforating effects distributed in space according to planes or according to helicoids corresponding to each peripheral coating

(preferably in V).

  The concentration of the perforating effects, according to the invention, according to these

  planes or propellers, creates sharp effects against the target.

  The combination of these sharp effects, with the blast effect, pro-

  cure, according to the invention (inherent in the device: "thin" peripheral coatings, therefore high explosive loading coefficient, for a mass

  given), increased efficiency, which causes disorganization of the area

  tint on the hostile, with concentrated destruction and "breaking" effect of the target, for large passage distances, up to

a few meters.

  This causes an "instant" interruption of the opposing mission.

  According to the invention, the piercing effects are driven at a very high speed, of the order of several thousand m / s, which facilitates the adjustment of the rocket close to the missile, projectile, or rocket which carries this charge. , depending on the presentation case, and thus provides increased efficiency of interception. The various characteristics and advantages of the invention will emerge

  from the description below It should be remembered, however, that this is only

  ment of examples, and that all other modes of construction, proportions, shapes, arrangements, etc., can also be used without departing from the

part of the invention.
