Definitions
- the technical field of the invention is that of ignition devices, in particular for propellant charging ammunition.
- Known ignition devices use a ignition pyrotechnic component or igniter.
- Patent FR2593905 describes such an igniter tube.
- current cartridge munitions present generally very long projectiles whose rear part or tail unit is housed in the vicinity of the igniter. It is therefore not possible to places in such ammunition an igniter tube long enough.
- Patent EP344098 describes such an ignition device. This device has the disadvantage of implementing a cord containing a pyrotechnic substance. This substance is likely to be initiated accidentally, leading to an unexpected ignition of the propellant charge.
- igniters use a share of energy electric to increase the temperature and pressure of propellants, so the initial velocity of the projectile.
- Known plasma igniters have a cylindrical structure close to that of an igniter tube conventional and they are difficult to associate with ammunition in which the projectile penetrates deeply to inside the propellant charge.
- the ignition device according to the invention can be associated with ammunition incorporating a projectile penetrating deep inside the load.
- the ignition device according to the invention can be safely installed in a load and it allows precisely control the ignition of a load chipboard.
- the subject of the invention is an ignition device for a propellant charge, comprising at least one means igniter, device characterized in that it comprises at least one inert diffuser tube extending through part of the propellant charge and allowing guide the flame generated by the inflammatory medium to an area receiving propellant charge.
- the diffuser tube will preferably be made of material flexible plastic and it may have a thickness included between 0.7 and 1.5 mm.
- the diffuser tube may have an internal diameter between 3 and 6 mm.
- the means igniter could be an electrical igniter generating a plasma (plasma torch).
- the device may include a relaxation room arranged between the outlet of the plasma igniter and the diffuser tube (s).
- the invention also relates to a loading propellant incorporating such an ignition device.
- This propellant charge will include at least one block of agglomerated propellant powder, block carrying at least one blind ignition channel intended to receive a tube Streamer.
- the loading may include at least two blocks of propellant powder agglomerated stacked on top of each other, at least a first block carrying at least one through link channel which is intended to receive a diffuser tube passing through said first block to be housed in an ignition channel fitted out on a second block.
- Each block could thus have three channels blind lighting regularly distributed angularly and intended to receive a diffuser tube.
- the loading includes at least three agglomerated blocks that have each three blind channels regularly angularly distributed and intended to receive a tube diffuser, the block closest to the igniter comprising also six through connecting channels and a block intermediate with three connecting channels the through.
- Figures 1 and 2 thus show a device ignition 1 according to a first embodiment of the invention.
- This device comprises an inflammatory means 2 to which three diffusing tubes 3 are connected.
- the device is shown here alone.
- igniter 2 is intended to be secured to a ammunition base (not shown).
- the body 5 of the means inflammator carries for this purpose a thread 4 which is intended to cooperate with a thread of the base.
- the inflammatory medium is here a plasma generator and it has two electrodes 6 and 7 separated by a case insulating cylindrical 8 made of a plastic material likely to ablate, i.e. to generate gas light by the action of a plasma.
- a case insulating cylindrical 8 made of a plastic material likely to ablate, i.e. to generate gas light by the action of a plasma.
- Such a case is generally called a capillary in known plasma igniters.
- the electrodes 6 and 7 are produced for example in a copper alloy. They are intended to be connected to a electric generator 35 via connections 36 and 37.
- a first connection 36 is in electrical contact by an appropriate means (e.g. a touch spring (not shown) with the rear electrode 6.
- a second connection 37 is in electrical contact with the metal body 5, for example by a touch to spring rests on the back of it or on the metal base of the ammunition (not shown).
- the generator 35 is designed to be able to deliver energy from 10 3 Joule to 10 6 Joule in the form of voltage pulses from 10 3 Volts to 20.10 3 Volts.
- a generator is conventional and includes, for example, capacitors, an inductor, thyristors and a stabilized power supply.
- the rear electrode 6 is generally cylindrical and of same axis as body 5. It extends inside case 8.
- the front electrode 7 is tubular and its axial bore has a nozzle profile having a conical profile converge 9 which is open on the side of the rear electrode 7 and which is followed by a divergent conical profile 10.
- This nozzle reduces thermal losses during level of plasma generated by the torch. Indeed the nozzle allows to return in the axis of the torch the gases located in periphery. These gases are thus heated by the plasma.
- the front electrode 7 is electrically connected to the body 5 of the igniter by the tight adjustment of its surface external cylindrical.
- the stack of the two electrodes and of the case 8 is immobilized by a nut 11, which is screwed into a thread 12 of the body 5, and which applies to a shoulder 6a of the rear electrode 6.
- the nut 11 is made in one insulating material.
- a fuse 13 is arranged between the electrodes 6 and 7. It has the shape of a tube produced in a conductive material associated with at least one material energetic or likely to react with the material driver.
- energetic material a material capable of supplying chemical energy in the form of a flame when it is initiated by the Joule effect generated by the flow of current through the material driver with whom he is intimately associated.
- the conductive material may consist of carbon or by a metal such as copper, aluminum, silver, tungsten or magnesium.
- a tube 13 formed of a layer of chlorofluoroethylene copolymer (known as Viton registered trademark) deposited on a layer of aluminum.
- the ignition device includes 3 diffuser tubes integral with the igniter
- diffuser tubes are made of plastic and are completely inert because they do not contain pyrotechnic composition.
- the tubes are made integral with the igniter by a connection sleeve 14 which is screwed at a threaded front end 5a of the body 5 of the igniter 2.
- This sleeve 14 carries three internal threads 15 regularly angularly distributed and whose axes 17 form an angle with the axis 16 of the body 5 of the igniter 2.
- Each internal thread 15 receives a tubular screw 18 on which fixes a lock nut 19.
- the tubular screw 18 has a conical surface 18a which cooperates with a complementary conical bearing 19a of the nut to ensure pinching, therefore immobilization and the tightness of the diffuser tube 3.
- the latter is made of a flexible plastic material, for example polyamide, polyethylene or polyolefin.
- the thickness of the diffuser tube is included between 0.7 and 1.5 mm, and the internal diameter of the tube diffuser is between 3 and 6 mm.
- the screw 18 and the nut 19 thus constitute a means of securing of the diffuser tube 3 with the sleeve connection 14, therefore with the igniter 2.
- Each diffuser tube 3 is intended to extend to the through part of the propellant charge (not represented). It guides the flame generated by the inflammatory medium to a receptor area of the propellant charge (not shown here). We can by example fix the diffuser tubes on the internal wall a round of ammunition.
- the flame produced by the medium igniter 2 is precisely conducted in one desired place of loading without an ignition effect radial through the diffuser tube is not to be feared.
- the thermal inertia of the material used is sufficient so that the flame is thus conducted without destroying the diffuser tube and this even when the ignition means generates a plasma (temperature of the order of 5000 K).
- the diffuser tube will be destroyed later by the temperature and pressure of the gases developed during the combustion of the whole propellant charge.
- the sleeve 14 delimits with the body 5 of the igniter 2 an expansion chamber 20 which is located disposed between the output of the plasma igniter 2 and the diffuser tubes 3. This expansion chamber allows to homogenize the plasma pressure and its chemical composition.
- the body 5 of the inflammatory medium will contain a flame-generating pyrotechnic composition.
- She may include an associated flame intensifier relay to an electrically initiated igniter.
- Figure 3 shows in partial longitudinal section a ammunition 21 equipped with an ignition device according to a second embodiment of the invention.
- This embodiment essentially differs from the previous in that it comprises nine diffuser tubes 3, divided into three groups, the tubes of the different groups having different lengths (here for clarity of the figure, only a few tubes are shown).
- Ammunition 21 includes a socket 22 made in a combustible material, for example cardboard impregnated with nitrocellulose, socket at the base of which is fixed a shutter base 23 which carries the inflammatory means 2 and receives on its internal surface a bowl 40 of material plastic.
- the base is fixed to the socket 22 by rivets radials 41 regularly distributed angularly.
- Ammunition 21 also includes a projectile 24 (here an under calibrated projectile stabilized by empennage) which is fixed to the socket 22 by a connecting piece 25 made for example plastic. Fixing the socket 22 on the connecting piece 25 will be secured by rivets (not shown).
- a projectile 24 here an under calibrated projectile stabilized by empennage
- a connecting piece 25 made for example plastic. Fixing the socket 22 on the connecting piece 25 will be secured by rivets (not shown).
- the propellant charge of this ammunition comprises at least one block of powder agglomerated propellant (here four blocks 26a, 26b, 26c, 26d).
- the blocks are produced for example by compression uniaxial (around 30 MPa) and hot (around 80 ° C) of propellant powder in grains impregnated with a binder thermoplastic or energetic.
- the compression will be done in a mold whose shape allows to obtain the geometry of the desired block.
- the rear unit 26a is in abutment against the bowl 40 disposed in the base 23.
- This block has a recess 42 which allows the radial deployment of the different tubes diffusers 3 around the inflammatory medium 2.
- the other three agglomerated blocks 26b, 26c and 26d carry three blind 28 ignition channels, regularly angularly distributed, each intended to receive a tube diffuser 3.
- Block 26b thus carries three channels 28b, the block 26c three ignition channels 28c and the block 26d three ignition channels 28d.
- Figure 7 shows an enlarged view of the blind end an ignition channel 28.
- This channel has an axis 29 parallel to axis 30 of ammunition 21 and it receives a diffuser tube 3.
- the tube 3 is not fixed to the block 26.
- a set 43 of a few tenths of a mm remain between the tube 3 and the channel 28.
- the diffuser tube 3 does not extend to the bottom of the ignition channel 28. There thus remains a chamber ignition 31 in which the flame conducted by the tube diffuser 3 can act and ensure localized ignition (but divided into three zones) of the propulsion unit 26.
- each block 26 simultaneously receives the flame supplied by igniter 2 and at its three ignition zones. he the result is better control over the evolution of pressure in the gun chamber and better ballistic performances.
- some agglomerated blocks also have canals through link 32 whose axis is also parallel to the axis 30 of the munition 21 (see Figures 4, 5 and 6).
- a first intermediate block 26c carries (in addition of its three blind ignition channels 28c) three channels of 32c link which allow the passage of the diffusing tubes 3d intended for the ignition of the upper unit 26d (see the figure 5).
- the second intermediate block 26b carries (in addition to its three blind ignition channels 28b) six link 32b which allow the passage of the diffuser tubes 3c and 3d intended for the ignition of the intermediate block 26c and of the upper block 26d (see FIG. 6).
- each agglomerated block 26b, 26c and 26d has an axial housing having a shape corresponding to that of projectile 24, and allowing in particular to receive the fins 34 of the empennage 33 of the projectile.
- Pawns 38 made of plastic, are disposed between the propulsion units 26b and 26c as well between propellants 26c and 26d. These pawns are regularly distributed angularly and allow ensure the angular connection of the different blocks to prevent shearing of the diffuser tubes 3. They also provide angular indexing of the blocks which allows the alignment of the different channels, thus authorizing the introduction of the tubes 3 after stacking of the blocks.
- pawns 38 will be provided between each block.
