Definitions

  • the present invention relates to the field of launching of charges or projectiles.
  • the present invention relates to the field of such launch systems for which it is necessary to control the ejection distance or the dynamic output of a load, for example the braking of a projectile at a determined distance.
  • the braking device is associated with a limited section of the wire.
  • the braking device is of the friction type.
  • the braking device is composed of a rigid structure, for example annular type, provided with a series of through perforations in which the thread is engaged, for example in a spiral, in a loop, in sinusoid, or in any other suitable configuration.
  • a device comprising a mortar body 10 centered on a O-O axis.
  • the body 10 has, at its base, a chain pyrotechnic 12 capable, during its implementation, of ensuring the launch or propulsion of a charge or projectile 40 placed at the opposite end of the body 10.
  • Such a body 10 and pyrotechnic chain 12, known per se, can be the subject of numerous variant embodiments. They will therefore not described in detail below.
  • the pyrotechnic chain 12 proceeds by generation of gas under pressure.
  • charge or projectile 40 can be the subject of numerous embodiments and will therefore not be described in detail below.
  • a wire 20 is provided, a first end 21 of which is fixed to the body 10, by example near the pyrotechnic means 12 or on the base of the body 10, while the second opposite end 22 of the wire 20, is fixed to the charge 40.
  • the wire 20 is associated with a braking device 30.
  • the braking device 30 is associated with a zone of the wire 20 intermediate between its two ends 21, 22.
  • the two sections of the wire referenced respectively 23 and 24 arranged on either side of the braking device 30 are each respectively arranged in a coil in the form of helices centered on the axis longitudinal O-O of the body and referenced respectively 25 and 26 on the Figure 1 attached.
  • the braking device 30 comprises a rigid washer 32 of annular type centered on the longitudinal axis O-O of the body and whose mean plane extends perpendicular to this axis.
  • the washer 32 has through holes 34 parallel to the axis longitudinal O-O of the body. Several passages can thus be provided through 34 equi-distributed or not on the washer 32.
  • passages 34 illustrated in the figure attached is not limiting.
  • the intermediate zone of the wire 20 is wound, for example in a spiral, looped, sinusoidal, or in any other suitable configuration, on washer 32 passing through some selected passages 34 as illustrated in Figures 1 and 2.
  • the number of passages 34 and the pitch of passages 34 selected for receive the wire 20 directly determine the friction braking force applied to the wire, during the traction exerted on it by the launching of the charge 40.
  • the system can easily be adapted for several applications by selectively choosing according to the selected application (and in particular the mass of the load 40 and / or the trajectory dynamics desired) the passages 34 required to obtain the expected braking force.
  • the washer 32 is machined so as not to present an edge opposite the path of movement of the wire 20.
  • the passages 34 are flared at their inputs and outputs respectively on the faces of the washer 32 to connect substantially tangentially to them and avoid injuring the wire 20 when moving it.
  • the internal periphery 33 of the washer 32 on which the wire 20 also moves is preferably rounded, for example in the form of an O-ring.
  • the initiation of the pyrotechnic charge 12 causes the pressure in the area between envelope 10 and the projectile or charge 40, causing his expulsion.
  • the wire 20 then loosens freely at its spool 26 adjacent to the load 40, while remaining slightly taut.
  • the coil 26 can be coated with wax or resin, or even any equivalent material.
  • the wire 20 translates into the passages 34.
  • the successive windings of the wire on the brake 30 create a tensile force controlling the dynamics of stopping the projectile.
  • the projectile or charge 40 thus undergoes, initially, during of the unwinding of the first coil 26 rapid speeding up (effect pyrotechnic), i.e. an almost constant displacement due to the tensioning of the wire due to the unwinding of the coil 26, then a constant and sustained deceleration due to the combined action of the unwinding of the coil 25 amplified by the brake 30.
  • wires 20 can be associated with a brake 30 and a single charge.
  • one or more 20 wires can be associated with several brakes 30 selectively interposed along the length of the wire 20 for manage braking dynamics.
