Definitions
- the technical field of the invention is that of security and arming devices for a pyrotechnic chain of a projectile and in particular micro-machined security and arming devices.
- Security and arming devices are well known. They generally comprise a screen closing a transmission channel which connects a detonator and a pyrotechnic charge.
- the screen is thus interposed on the transmission of the detonation wave between the detonator and the load and it prevents the operation of the latter.
- the patent US6964231 discloses such a micro-machined security and arming device comprising a flap carrying a pyrotechnic charge and sliding by the action of the force centrifugal. This shutter itself is immobilized by a lock that is erased by the acceleration of firing of the projectile.
- the rocking latch is actuated by a pyrotechnic composition generating gas whose ignition is controlled by an electronic means.
- Such a safety device and armament allows to use for arming two independent environmental conditions: longitudinal firing acceleration and centrifugal acceleration. This double security allows this device to comply with the highest standards of projectile arming safety (STANAG 4187).
- the second latch (rocking latch) requires the implementation of a pyrotechnic composition and means of initiation thereof.
- An electronics must therefore be provided to control the operation of this MEMS which is therefore unsuitable for use in ammunition of medium caliber (caliber less than 50 mm) for which the available volume is limited.
- centrifugal feeder that maintains a latch engaged in a flap footprint.
- the maintenance of this lock by the weight and throughout the race of the latter generates friction that disturb the movement of the flyweight, so the delay of centrifugal arming.
- the object of the invention is to propose a micro-machined safety and arming device that does not have such a disadvantage.
- the device proposed by the invention makes it possible to ensure a release of the shutter as a result of the displacement of a centrifugal feeder but without the lock disrupting the movement of said feeder.
- the subject of the invention is a micro-machined or micro-engraved security and arming device for a pyrotechnic chain of a projectile which is animated when firing an axial rotational movement, a device comprising a substrate on which is provided a pyrotechnic chain interruption flap which is movable in translation on the substrate, in which device the chain interruption flap is held immobilized by at least two bolts, a first latch (or axial acceleration latch) which is released as a result of the application of the acceleration communicated to the projectile during firing and a second latch which is a centrifugal latch released as a result of the rotation of the projectile, characterized in that the second latch comprises at least one finger of tilting lock which is interposed between the substrate and the flap, finger oriented in a direction parallel to the direction of movement of the flap and comprising a surface e support against which applies the shutter in the locked position, the finger further comprising an extension, and the device incorporating a feeder disposed in a housing of the shutter and sliding under the effect of the
- the second lock comprises two locking fingers symmetrical to one another with respect to a median plane of the device parallel to the direction of movement of the flap.
- each finger extends inside the feeder housing, the latter also having inclined planes which cooperate with the extensions of the fingers to cause their tilting.
- each finger forms with its extension a right angle, the extension being in the vicinity of the bottom of the cavity receiving the flap on the substrate.
- Each finger can be connected to the substrate by a pivot-type joint which will be positioned at the angle between finger and extension of the finger.
- Each joint can also be immobilized by a breakable type of locking means which will be broken by the support of the flap.
- the device may comprise damping means comprising a flexible tongue integral with the substrate and against which the extensions of the fingers will bear when they are pushed by the flyweight at the end of the latter.
- each finger may carry at its end a tooth which bears against the weight in a safety position of the device, the weight also comprising notches in which the teeth are lodged when the weight tilts the fingers.
- the figure 1 shows a projectile 1 of medium caliber (caliber less than 50 mm), which comprises a body 2 of axis 2a containing an explosive charge 3.
- the body 2 receives at its front part a rocket 4 which is screwed into a tapping of the body 2
- the fuse 4 comprises a housing 8 which contains a firing charge 5.
- the firing load 5 is intended to be initiated by a pyrotechnic chain comprising a detonator 6 and a relay 7 (alternatively this relay 7 could be omitted and the detonator 6 would then directly initiate the priming charge 5).
- the detonator 6 is here a percussion detonator which is initiated by a striker 9 slidably mounted in a nose 10 integral with the housing 8 of the rocket 4.
- the firing pin 9 is projected on the detonator 6.
- the firing pin is held in place during the storage and firing phases by a shear washer 11.
- the rocket 4 also contains a security and arming device 12 which makes it possible to interrupt the pyrotechnic chain during the storage and firing phases of the projectile 1.
- this safety and arming device is made in the form of a micro-machined or micro-engraved device (MEMS). It thus comprises a substrate 13 on which is mounted a sliding shutter 14 which ensures the interruption of the pyrotechnic chain.
- MEMS micro-machined or micro-engraved device
- the substrate 13 has two orifices 15a and 15b disposed on either side of the flap 14.
- the detonator 6 must have the minimum size to ensure operation and it will be coupled to a suitable pyrotechnic relay 7 (or 5).
- a detonator comprising a 10 milligram output stage of Hexogene coupled to a very insensitive relay, for example in HNS (hexanitrostilbene), it was possible to make orifices 15a, 15b (or transmission) of less than 1 mm 2 section (channel diameter of the order of mm) while guaranteeing the desired initiation transmission.
- the projectile 1 is also provided with a belt 2b which takes the stripes of the barrel of the weapon (not shown) and which communicates to the projectile 1 a rotational movement about its axis 2a during firing.
- the figure 2a shows in greater detail the internal structure of a first embodiment of the security and arming device 12 according to the invention.
- the device therefore comprises a substrate 13 on which is disposed a pyrotechnic chain interruption flap 14 which is movable in translation on the substrate in a cavity 31.
- the flap 14 is made by micro-machining or micro-etching according to MEMS production techniques which are well known to those skilled in the art.
- orifices 15a and 15b which are disposed on either side of the flap 14 and the axis 16 of these orifices (thus the direction of action of the pyrotechnic chain).
- the dimension L of the flap 14 ensures the interruption of the pyrotechnic chain in the safety position of the device 12.
- the chain interruption flap 14 is held immobilized by two bolts.
- a first latch 17 (or axial acceleration latch) and a second latch 18 which is a centrifugal latch released as a result of the rotation of the projectile 1.
- the axial acceleration latch 17 is constituted here by two breakable tabs which connect the flap 14 to the substrate 13 (so-called "break" tabs).
- the figure 3 shows enlargedly an embodiment of such a tongue 17a.
- the tabs 17a ensuring the suspension of the flap are oriented so that the axial inertia forces that will exert on the flap 14 when firing the projectile will cause their rupture.
- the tongues 17a will be dimensioned such that this break only occurs for the inertia forces related to the firing and not during the shocks received by the device during the handling phases or during the logistics operations.
- the width e of the tongue 17a will thus be calibrated to break during an acceleration of the order of 50000 m / s 2 , which is the order of magnitude of the accelerations experienced by the projectiles of medium caliber (lower caliber or equal to 40mm).
- the axial acceleration latch 17 may be produced in the form of tongues urged in tension or else tongues stressed in shear or in compression or a combination of several types of tongues.
- the second latch 18 (or centrifugal latch) comprises at least one tilting locking finger 18a which is interposed between the substrate 13 and the flap 14.
- the second latch comprises two locking fingers 18a which are symmetrical to one another with respect to a median plane of the device, plane parallel to the direction of displacement 19 of the flap 14.
- Each finger 18a is substantially oriented in a direction parallel to the direction of movement 19 of the flap 14. It has a thinned end 18b which connects it to the substrate 13 and which constitutes a flexible connection.
- the finger 18a has a bearing surface 18c which forms a heel against which the flap 14 is applied in its locked position as shown in FIG. figure 2a .
- the finger 18a further comprises an extension 18d which extends inside a housing 20 arranged inside the flap 14.
- the housing 20 receives a feeder 21 which slides in this housing 20 under the effect of the centrifugal acceleration.
- the weight is held in abutment against the bottom 22 of its housing by a compression spring 23 which is also micro etched and which connects a stud 24 (integral with the substrate 13) and the weight 21.
- the spring 23 penetrates inside a chamber 21a internal to the weight 21.
- the weight 21 moves in a direction 19 which is the same direction of displacement as that of the flap 14 and which is also a direction perpendicular to the direction of action 16 of the pyrotechnic chain.
- the axis 19 corresponds to a radial direction of the projectile and the centrifugal inertia can be exerted on the flyweight 21 and the flap 14.
- the integration of the device in a projectile is therefore extremely simple despite the reduced dimensions for this device 12. Indeed the pyrotechnic alignment of the axis 16 necessarily leads to a correct orientation of the device relative to the projectile.
- Braking means are provided to slow the movement of the weight 21 and the flap 14.
- These means comprise reliefs or indentations 25 which are formed on the walls of the housing 20 which are parallel to the direction 19.
- the indentations 25 cooperate with reliefs or complementary indentations 26 which are integral with the weight 21.
- the latter comprises indentations 26 symmetrical on each of its faces in contact with the walls of the housing 20.
- the profile of the indentations is triangular. This profile could have a different shape: rounded or rectangular.
- the indentations 26 secured to the weight 21 are carried by a flexible tongue 27 integral with the weight 21 and which is delimited by the etching of an opening 28 in the weight 21.
- the indentations 25 of the shutter are in fact substantially in contact with the lateral faces of the weight. Note that with such a reduced game, a "zigzag" movement of the flyweight 21 (as in known devices) would be impossible. Furthermore, since the indentations carried by each lateral face of the weight are symmetrical, the displacement of the weight 21 is rectilinear in the housing 20.
- the friction ensures a braking and therefore a delay of the displacement of the weight 21.
- the figure 2a shows the device in its safe position, the one it has inside the barrel of the weapon before firing.
- the firing acceleration results in the appearance of an axial inertia force which will cause the tabs 17a of the first latch 17 to break, which releases the flap 14.
- the flap 14 is, however, always maintained in the safety position by the centrifugal latch 18.
- the figure 2b shows the device in the position that it adopts after its exit from the tube of the weapon and at a distance of the order of fifteen meters.
- the centrifugal acceleration has caused the appearance of a radial inertia force acting on the flyweight 21.
- the flyweight has progressively moved away against the action of the second spring means 23 and being slowed by the friction of the indentations 26 of the weight 21 on those 25 of the housing 20 of the flap 14.
- the stiffness of the spring means 23, and the braking means 25,26,27 are defined so as to delay the passage of the weight 21 to its unlocked position, so that the configuration according to the figure 2b only intervenes at about fifteen meters from the tube of the weapon. It will be possible to play on the number of indentations 26 carried by the weight 21 and the flexibility of the tabs 27.
- the weight 21 comprises inclined planes 40 which cooperate with the extensions 18d of the fingers 18a to cause their tilting towards the stud 24.
- the flap 14 no longer closes the orifices 15a, 15b.
- the direction of action 16 of the pyrotechnic chain is released and the device is in the armed position. An impact on a target will initiate the explosive charge of the projectile.
- the flap 14 is locked in its armed position by tabs 29 integral with the substrate 13 and which engage in notches 30 arranged on a side surface of the flap 14 so as to prohibit the return of the latter to its seat. security position.
- the device according to the invention is extremely simple and compact. It has a totally mechanical structure and can be incorporated into a medium caliber projectile at a lower cost.
- the device according to the invention makes it possible to ensure a displacement of the flyweight 21 (thus a timing of the armament) which is not disturbed by the friction on the bolts of the shutter. Indeed, the fingers 18a constituting these locks are released only after complete displacement of the weight.
- the device according to the invention makes it possible to define a sufficiently large arming delay (about fifteen micro seconds) despite a relatively small stroke of the shutter 14.
- FIGS. 5a to 5c show a second embodiment of a device according to the invention.
- the lock here comprises two locking fingers 18a which have substantially an "L" shape. Each finger 18a thus forms with its extension 18d a right angle. Furthermore, the extension 18d is in the vicinity of the bottom 31a of the cavity 31 of the substrate 13 receiving the flap 14.
- Each finger 18a is connected to the substrate 13 by a hinge 32 of the pivot type which is positioned at the angle 33 between the finger 18a and the extension 18d of the finger.
- the hinge 32 is made of course by micro-etching or micro-machining. This operation will be conducted so as to leave a brittle bridge 34 which will play the role of locking means of the finger. This bridge will be broken when the flap 14 will press against the fingers 18a under the effect of the centrifugal acceleration after breaking the first latch 17.
- each finger 18a bears on a bearing surface 35 arranged on the flap 14.
- the flap 14 is thus locked in translation by the fingers 18a.
- the weight 21 comprises as in the previous embodiment indentations 26 carried by a flexible tongue 27 integral with the weight 21 and defined by the etching of an opening 28. These indentations 26 cooperate with indentations 25 carried by the walls of the housing 20 which are parallel to the direction 19 to constitute a braking means for both the movement of the flyweight 21 and that of the flap 14.
- the front portion 36 of the weight 21 which is intended to come into contact with the extensions 18d of the fingers 18a a here a form of reduced width. Such an arrangement makes it possible to receive the fingers 18a between the weight 21 and the flap 14 when the latter adopts its armed position visible to the figure 5c .
- a specific means which consists of a flexible tongue 38 which is micro-machined in the substrate 13 and which is delimited by a cavity 39.
- the figure 5a shows the device in the safety position.
- the figure 5b shows this device after complete displacement of the flyweight 21, so after the delay provided by the braking means 25, 26,27, but before the displacement of the flap 14.
- the figure 5c finally shows the device in the unlocked position after displacement of the flap 14.
- the figure 6a is analogous to the figure 5a and shows the device in the safety position.
- the figures 6b and 6c correspond to the figures 5b and 5c and show the device during various stages leading to its arming.
- the lock always comprises two locking fingers 18a which have substantially an "L" shape, but each finger 18a carries at its end a tooth 41 which bears on a lateral edge of the weight 21 in the position of device security ( figure 6a ).
- the tooth 41 is substantially perpendicular to the finger 18a, therefore parallel to the extension 18d of each finger 18.
- the weight 21 has notches 42 at its side edges on which the teeth 41 are supported. These notches 42 allow to receive the teeth 41 when the weight 21, at the end of the stroke, tilts the fingers 18a.
- the flap 14 is unlocked. He can then adopt his armed position visible to the Figure 6c .
