Definitions
- the field of the present invention is that incendiary compositions and projectiles using such compositions.
- Incendiary compositions of known type are generally intended to be projected on a target using a vector.
- Incendiary materials exhibiting such characteristics are most often hydrocarbons gelled and doped.
- hydrocarbons present very high reaction heats from 33.5 to 41.9 KJ / g (from 8 to 10 Kcal / g). They are gelled and doped with substances pyrotechnics (such as redox couples), in order to improve their operating characteristics (combustion time, reaction temperature, ignition sensitivity, ability to transmit to support the calories produced).
- pyrotechnics such as redox couples
- the dispersion is carried out by means of an explosive cane arranged in the axis of the incendiary charge.
- the thermal effect produced by the explosive cane must also ensure initiation of the incendiary composition.
- Patent FR2624962 thus describes a head incendiary military whose composition is everything first dispersed by means of a sliding piston then initiated.
- US2534215 describes an ammunition comprising an incendiary fluid inside which are distributed grains which are ignited by the fluid incendiary and which are intended to increase efficiency of it.
- Patent DE302600 shows a composition incendiary associated with an ignition composition particular including perchlorate, nitrated hydrocarbon and sawdust.
- the goal here is to improve ignition and effectiveness of the incendiary composition.
- the ignition composition is either separated from the incendiary composition is mixed with it.
- Patent DE1171319 describes a composition incendiary which may include granules of material fuel having both an agent function thickening and allowing a re-ignition of the incendiary if it goes out.
- Patent US3881968 describes a bomb incendiary containing a composition associating the naphthalene with an ignition material (magnesium / Teflon) which vaporizes naphthalene to disperse it through orifice of the bomb. The initiation of naphthalene intervenes in contact with air after its dispersion. If these documents suggest compositions to improved incendiary efficiency, they do not allow to jointly solve the problems of dispersion and that of the initiation of an incendiary composition to solid state.
- an ignition material magnesium / Teflon
- incendiary composition proposed by the invention is both easy to disperse and to initiate.
- this incendiary material may be associated with 5 to 15% by mass of a ignition composition comprising 30% by mass of magnesium, 54% by mass of polytetrafluoroethylene (or Teflon) and 16% by mass of a chlorofluoroethylene copolymer (known as Viton brand).

- a ignition composition comprising 36% by mass of Magnesium, 28% by mass of iron oxide (Fe3O4), 28% by mass of ammonium nitrate and 8% by mass of polyfluoride vinylidene (PVDF).
- the subject of the invention is also a incendiary projectile comprising such a composition in place in a containment envelope which breaks when from initiating the projectile to release the composition and also comprising pyrotechnic means ensuring cracking of the incendiary charge and initiation of a part of the grains of the ignition material, the means pyrotechnics being sized so that they do not can break the containment

- connection between the tube 16 and the housing 18 is obtained by an annular crimp 20 of the end of the tube 16 on the bottom of the housing 18.
- a plug 21 is supported by a shoulder 22 on the front cover 9, it is fixed by gluing on the cover 9.
- the case 18 extends in the load 7 over a length L1 from the front cover 9.
- the length L1 is preferably chosen to be understood between 20 and 50% of the total length L2 of the loading 7 for reasons which will be specified by the after.
- vents 23 regularly distributed over its entire surface cylindrical. These vents have the function of allowing ignition of the incendiary charge as it will explained later. They are closed in a way known by metallic flakes, made for example by sticking a sheet of tin on the cylindrical surface internal of the housing 18.
- the tube 16 contains a cord 24 of transmission and fast ignition which is constituted by example by a pyrotechnic composition placed in a polyethylene sheath.

- the material constituting the grains 27 of the ignition material is chosen on the one hand according to its ability to initiate incendiary material 26 chosen, and secondly according to its own sensitivity to flame and hot gases, since this material must itself be initiated by the composition 25.
- the rate of propagation of the reaction of the grain material 27 will be chosen between 1m / s and 3000m / s, to ensure rapid initiation from close close to the grains 27 before the envelope 2 bursts.
- the grains 27 of the ignition material will calibrated with an average dimension between 0.1mm and 10mm and preferably between 3 and 6mm.
- the shape of grains can be any but will preferably be spherical or spheroidal.

- a sensitizing compound like Nitrocellulose or Ammonium Perchlorate
- a binder such as PVDF (Polyfluoride of Vinylidene) or Viton (registered trademark).
- composition is then granulated (passage to through a sieve whose mesh void is adapted to the desired particle size).
- the mass ratio between all the grains 27 and the incendiary material 26 will depend on the sensitivity of the incendiary composition and characteristics of the constituent material of the grains.
- the preferred proportions will be those of a mixture of 5 to 15% by mass of ignition material and 95 to 85% by mass of incendiary material.
- Incendiary composition according to example M1 of 85 to 95% by mass
- Ignition composition according to example A1 from 5 to 15% by mass.
- Incendiary composition according to example M2 of 85 to 95% by mass
- Ignition composition according to example A2 from 5 to 15% by mass.
- Incendiary composition according to example M3 of 85 to 95% by mass
- Ignition composition according to example A3 from 5 to 15% by mass.
- Incendiary composition according to example M4 of 85 to 90% by mass
- Ignition composition according to example A4 from 10 to 15% by mass.
- the rocket 14 initiates the relay 12.
- the latter turns on the cord 24 which has the function of quickly initiating the ignition and dispersion composition 25 (with a delay less than 2ms) without disturbing the loading incendiary 7.
- Ignition composition 25 generates gases hot and flames coming out of the case 18 through the vents 23.
- the ignition composition 25 is dimensioned so as not to be able to break the confinement achieved by the casing 2 and the front and rear covers 8 and 9.
- the envelope 2 which ensured the containment of the beginning of the reaction, breaks and the incendiary charge is dispersed outside in the form of fragments.
- Each fragment has a part of material incendiary 26 carrying one or more ignition grains 27 who are initiated and who in turn ensure ignition of the incendiary material 26.
- the distribution of ignition grains within the incendiary composition thus makes it possible to resolve the problem of the dispersion of the composition in the form of flaming fragments thanks to the chronology of load operation. Indeed, it is the initiation step by step of the ignition grains which ensures the fragmentation of the incendiary charge then the bursting of the envelope.
- Each fragment of composition that is dispersed thus takes its own source of initiation under the form of one or more grains of ignition material ignited disposed on the surface of the incendiary material. This ensures ignition of the incendiary material after the fragments are dispersed.
- composition incendiary proposed by the invention is little sensitive to external stresses (shocks, vibrations), since the most sensitive part (the grains of ignition material) is embedded in a insensitive material (incendiary material).
- the housing 18 is carried by the front cover 9 and that it extends in the loading 7 over a length L1 of less than 50% of the total length L2 of the load 7.
- Such an arrangement has the effect of advancing the initiation reaction of the charge in a direction which is both radial around the housing 18, and axial of the part front 4 towards the rear part 3 of the projectile.
- the envelope 2 and the covers 8 and 9 could for example be made of material plastic or composite, for example coiled filamentary.
- Envelope 2 may have primers of breaks of particular shapes in order to give a particular distribution for the fragments of the incendiary composition.
- Figure 2 gives an example of a variant in which the front cover 9 has a conical shape converging towards the rear part 3 of the projectile.
- This shape is particularly well suited to radial dispersion upon impact of the projectile on a target.
- the cone of the lid opens and this deformation has the effect of pushing back the load incendiary towards the rear and to favor its dispersion radial.
- Figure 3 summarizes the different phases of a particular method of manufacturing a projectile according to the invention.
- a second thermostatically controlled enclosure E2 receives through an orifice supply O1 all incendiary material from E1. It also receives through an orifice supply O2 the ignition grains from a distribution system S.
- Distribution system S provides mass of 27 grains which is necessary for mass incendiary supplied by E1.
- a stirrer A homogenizes the mixture of grains 27 and incendiary material 26.
- valve V By means of valve V, it flows into this envelops the quantity of incendiary composition required (phase P1).
- phase P2 Let cool and solidify the composition, then place a layer 28 of resin to fill the clearances after cooling (phase P2).
- the envelope containing the load is then ready to receive other elements so as to constitute the incendiary projectile 1 (rocket, warhead, empennage, propellant ).
- composition incendiary including a binder, carry out the loading by cold or hot compression.
