Definitions
- the invention relates mainly to an open chamber weapon.
- the field of the present invention is that of automatic weapons systems of small and medium caliber; more particularly open-chamber weapons intended for firing telescoped munitions.
- the ammunition to be fired must be introduced longitudinally into a chamber. This operation is carried out by means of mechanisms driven by alternating translational movements of large amplitude.
- the introduction stroke is o greater than or equal to the length of the ammunition. This configuration generates considerable travel speeds and accelerations, which quickly limit the rate of fire. Since the chamber of this type of weapon is always constituted by a bore made in a "one-piece" member, there is no other alternative than a longitudinal introduction.
- An open chamber is constituted by at least two parts which are movable relative to one another, and the assembly of which determines a cavity in the profile of the munition to be fired.
- weapons with an open chamber comprise a cylindrical rotor having at its periphery one or more grooves parallel to its axis and whose profile corresponds to that of the munition; this rotor rotating inside a cage having lateral openings in order to allow the introduction of the ammunition and the ejection of the empty casings.
- the chamber is closed at the shooting station by the cage or by a mobile segment.
- the ammunition fired 5 in this kind of weapon is almost always of triangular section with curvilinear sides. The radius of curvature of the sides being equal to the radius of the rotor. This concept allows lateral introduction of the ammunition. It follows translational movements of low amplitude allowing much higher rates of fire. 0 Other important advantages ensue:
- French patent 164601 published under the number FR 1603956 proposes a mechanism for ammunition without casings, animated by an oscillating movement and being able to fire either telescoped ammunition or ammunition of classical architecture without casings. Sealing with combustion gases is achieved by means of one or more intermediate parts cooperating with smooth surfaces of the rotor and using, as the case may be, the pressure developed by said gases.
- This system can be blamed for a seal based on parts which are not locked in the firing position, a position which therefore risks being uncertain and sensitive to fouling, especially in the version adapted to a conventional munition architecture, defect prohibiting for example the use of such a weapon on board an aircraft where a significant number of ammunition without casings could be in the immediate vicinity of the breech and therefore of possible propellant gas leaks. There is a risk of explosion.
- the patents published under the numbers FR 1159282, FR 1604264 and US 2847784 all relate to telescoped ammunition with sockets of substantially triangular profile and aim to reduce the friction attributable to swelling of the socket after firing.
- the patent published under the number FR 1159282 describes a weapon constituted by a rigid breech frame in which a cylindrical rotor can rotate, having machining operations on the profile of the socket. Between the frame and the rotor there is a movable part whose face located opposite the rotor is cylindrical, of the same radius as the latter; the opposite surface being in contact with the frame according to a sliding surface inclined relative to the first.
- This part is subjected to the action of a spring tending to wedge it between the rotor and the frame, so as to close the chamber.
- US Pat. No. 2,847,784 describes a weapon, the frame and the rotor of which are each made in two parts fitted one inside the other and whose internal part has dimensions slightly greater than those of its housing in the external part.
- the fitting is carried out either by heating and expansion of the female part, or by cooling and contraction of the male part, or by joint use of the two techniques.
- This embodiment generates forces antagonistic to those induced by the swelling of the cartridge after firing. This avoids a passage of the chamber material in the plastic area and it is hoped that the expansion of the sleeve will not go beyond the limit
- Obtaining high firing rates means resorting to complex feeding mechanisms which risk being heavy, costly and unreliable (patents published under the numbers FR 1603954 and FR 2006285). Furthermore, the choice of the seal based on the expansion of the sleeve, in addition to the problems of jamming resulting from the permanent deformation of said sleeve and of energy absorption previously mentioned, entails a risk of tearing in the corners, therefore leaks, making this concept unreliable. Thus, the patent published under the number FR 1603739 provides for strengthening the angles of the socket. Finally, a triangular section socket has an unfavorable bulk / mass ratio of powder, compared to a cylindrical or square section munition. To overcome the drawbacks of the known technique, the weapon according to the invention offers a response on two levels.
- a device was designed ensuring the stiffening of the chamber and making it possible to limit the deformation of the socket while making " its easy extraction. This device can be integrated into the preceding weapon and can adapt to all forms ammunition.
- the main object of the invention is an open chamber weapon comprising a rotor for bringing the ammunition into the firing position, characterized in that it comprises means for constituting a firing chamber surrounding the ammunition during the firing phase, means for locking the firing chamber during the firing phase, means for unlocking the firing chamber after the firing phase to facilitate the evacuation of the cartridge case, even if it has undergone expansion during and / or after firing.
- the subject of the invention is a weapon, characterized in that the firing chamber is constituted, on the one hand by an imprint of the rotor, and on the other hand, by two imprints belonging to two segments, linked with the rotor, the segments being able to undergo a rotation movement of limited amplitude relative to the rotor.

- the weapon can fire ammunition of different profiles, from a basic architecture requiring only few modifications to pass from one ammunition profile to another.
- the weapon comprises a tube 1 locked by teeth 2 in a body 3 and immobilized in rotation by the lock 4.
- the body 3 closed at its rear part by a cover 5 ensures the rotational guidance of the rotor 6, of the segments 7 and of the latches 8 (FIG. 2).
- the segments 7 have a rotational movement relative to the rotor 6 limited by the keys 9.
- a casing 10 contains the control cam 11 integral with the cams 12 and 13 which drive the roller carrier 14 in a movement d intermittent rotation.
- the mechanism of the weapon is driven by a motor 15, the output shaft of which meshes with the crown 16 formed on the periphery of the control cam 11.
- the ammunition is fired by means of a striker 17 whose operation will be described later.
- the keys 9, integral with the rotor 6 ensure the drive and the limitation in rotation of the segments 7 relative to said rotor 6.
- the locks 8 are constituted by a cylinder on which is cut an imprint 20 which, according to their orientation, allows the mobility or ensures the locking of the segments 7.
- the rear end of each of these latches 8 is constituted by pinions 21 and 22 which mesh respectively with pinions 23 and 24 whose axes of rotation are integral with the cover 5.
- the pinion 23 also has a crank arm 25 terminated by a roller 26 ( Figure 3).
- the ammunition is brought in by means of a ratchet feed 27 (FIG. 8). These are actuated in a reciprocating movement by the levers 28 hinging on a housing 29, themselves controlled by a lever 30 articulated in a clevis 31 of the cover 5 ( Figure 3).
- the lever 30 is driven by the carriage 32 provided with a roller 33 and which is guided by a slide 34 (FIG. 4) cut in the partition 35 of the housing 10.
- the control cam 11 carries, cut on its front face, a groove ABCD (figure 5). On its rear face is cut a circular groove 40, eccentric by 5 relative to the axis of rotation (figure 7) in which the roller 33 circulates.
- a boss 36 on the front face strikes a lever 37 (figure 6) articulated on the cover 5.
- the shock on the lever 37 is transmitted to an ejector 38, associated with a spring 39.
- the motor 15 for example electric, hydraulic or pneumatic, rotates the control cam 1 1 which performs one revolution complete per firing cycle.
- FIG. 8 represents the position of the parts (rotor 6, segments 7 and latches 8) before the chamber is closed and locked.
- the path C-B of the groove corresponds to the 120 ° rotation of the rotor 6 and its segments 7.
- the hub of the control cam 11 carries a groove 45 in which a stud 46 of the striker 17 moves. While the roller 26 traverses the DCB part of the groove of the cam 11, through the stud 46, the groove 45 causes compression of the spring 47 of the striker 17. When the roller 26 arrives at point A of the groove of the cam 11, the stud 46 is released by the groove 45 and, under the impulse of the spring 47, the striker 17 goes strike the primer of the ammunition.
- a trigger system ensuring the firing stop and the immobilization of the weapon is composed (figure 9) of a snowman 49 pushed by a spring 50, said snowman falling in the housing 51 of the cam 11 (figure 7) and thus ensuring that the shot is stopped.
- the snowman 49 is mounted in a support 52 pivoting in the partition 35 ( Figure 4).
- REPLACEMENT SHEET shown housed in the space 53 ( Figure 1) is compressed between the support boss 52 and the fixed stop 54 ( Figure 4).
- the sudden stop of the cam 11 by the snowman 49 is absorbed.
- the erasing of the snowman 49 is ensured by an electromagnet not shown.
- the stop of the shot intervening when the cam 11 has turned by an angle of 30 ° after the point A of percussion this same mechanism can also be used to stop the weapon in the event of long fire, which does not present any disadvantage since the angle of rotation of the cam 11 during which the chamber remains locked is 90 ° and that it remains 60 ° to absorb the shock caused by the sudden stop of the weapon.
- the non-initiation of the ammunition is detected in a known manner, either by the recoil of the weapon, or by a gas intake acting on the snowman 49.
- This type of weapon makes it possible to fire telescoped ammunition with casings of which a possible architecture is represented by figure 10.
- the section of these ammunition can have forms A, B or C.
- FIG. 11 represents a mechanism operating on the same principle but allowing the firing of square section ammunition, of the type B of FIG. 10.
- a rotor 6a There is a rotor 6a, segments 7a, latches 8, keys 9 and the ratchet feed 27.
- the kinematics of the system is identical to that described above.
- it has a particular feature constituted by the presence of a slope 62 in the feed chute which makes it possible to offset the ammunition and to facilitate their gripping by the pawls 27.
- FIG. 12 represents a mechanism making it possible to fire prismatic munitions of curvilinear square section, of the type C of FIG. 10.
- the rotor 6b differs significantly from the rotor 6 in that it has at each of its ends a plate 55, of small thickness, intended to drive the ammunition from the feeding station to the shooting station. By means of the pins 56, the plate 55 ensures the rotation drive of the segments 7b. In this version, the movement of the segments 7b relative to the rotor 6b is low. Power is supplied by a mechanism identical to that of previous versions, except that it has a double set of pawls 27b.
- FIG. 13 represents a feeding mechanism specially adapted to cylindrical ammunition.
- the ratchet feed is replaced by a star 57 enclosed in a casing 58.
- This star 57 is driven in a uniform rotational movement and makes 1/3 of a turn per cycle. It is driven by the motor 15 which in this case has an output pinion 59 meshing in the double pinion 60, which pinion drives a pinion 61 secured to the feed star 57.
- Such a device o makes it possible to simplify the cam command 1 1 by removing the groove 40.
- the chamber is always delimited by mobile elements (rotor ⁇ , 5 segments 7) locked around the ammunition during firing and which can then move away to release the empty cartridge case to be ejected.
- This arrangement eliminates the friction problems caused by the swelling of the socket after firing;
- a single cam 1 in direct contact with the energy source 0 controls the various organs and operating sequences. This results in high reliability and high operational reliability insofar as the unexpected stopping of one of the organs automatically results in the complete stopping of the weapon;
- the double cam system 12 and 13 (Ferguson system) 5 controlling the intermittent rotation of the rotor 6 guarantees a rigorous positioning thereof when locking the segments 7;
- the basic version can very easily be modified in order to fire ammunition of different shapes, in particular of square section, representing the best compromise between dimensions and useful mass;
- Figure 14 is an axial section AA of such a weapon, on which there is the tube 1 locked by teeth 2 in the body 3 and immobilized in rotation by the lock 4.
- the body 3 closed at its rear part by a cover 5, guides the rotor 6c in rotation, two latches 63, a closing valve 64 and its locking cylinder 65.
- the casing 10 contains the control cam 11 secured to the cams 12 and 13 which cause the intermittent rotation of the roller carrier
- a motor 15 can also be seen, the output shaft of which carries a pinion which meshes with the crown 16 machined at the periphery of the control cam 11.
- the rotor 6c has three grooves 66 at 120 ° which serve as a firing chamber. At each end of these chambers there are extractors 67.
- a lever 68 articulated in a clevis 69 of the cover 5 is supported on the ejector 38 associated with its spring 39.
- the latches 63 are constituted by a cylinder on which is cut a flat . The end of these latches has a pinion 70 which meshes with racks 71 (FIG. 15) cut in a fork 72.
- the locking cylinder 65 has a flat to the right of the closing valve 64. Its rear end consists of a cam 73 and a crank 74 carrying a roller 75. The cam 73 rotates inside a window 76 of the fork 72.
- the motor 15 drives the cam 11 which makes one complete revolution per firing cycle. While the roller 75 runs through the part B-A-D-C of the groove 77 of the control cam 11, ie a rotation of 1/2 turn, the pawls 27 advance a munition in the groove 66 of the rotor 6c
- the roller 75 runs through part C-B of the groove 77, the cams 12 and 13 rotate the roller holder 14 by 120 °. This ° rotation is transmitted to the rotor 6c by means of the pinions 41 and 42; and the ammunition is brought in front of the tube 1 to be fired. During this same time, the pawls 27 have positioned themselves behind the next munition to be fired.
- the percussion process uses the same elements and 5 works in the same way as in the basic version.
- the roller 75 goes from B to A in the groove 77, which induces a rotation of the locking cylinder 65 and of the cam 73 which in turn will cause a translation of the fork 72 , therefore racks 71 and consequently the rotation of the latches 63.
- the chamber is locked by the cylinder 65 pressing on the closing valve 64 (FIG. 16); and the rotor 6c is immobilized by the latches 63.
- Unlocking is carried out when the roller 75 goes from 5 D to C, according to a process opposite to that of the locking; said roller 75 finding in C a position such that it is no longer stressed, until it finds itself again in B.
- the passage from C to B corresponds to the rotation of 120 ° of the rotor 6c.
- the lugs 78 of the extractors 67 follow o grooves 79 and 80 cut respectively in the body 3 and the cover 5 and whose geometry is designed so as to cause the pivoting of the extractors 67 so that they tear off the empty socket of the groove 66. Then the boss 36 of the cam 1 1 strikes the lever 68 which transmits the shock to the ejector 38.
- the empty socket is evacuated through the orifice 81 machined in the body 3.
- the "long fire" trigger and safety systems are identical to the systems used on the original weapon.
- SHEET D socket are sufficiently weak, a simplified version, as shown in Figure 17, can be considered. In this case, it is possible to remove the latches 63 and 65 as well as their control members, including the groove 77 of the control cam 11. We can even envisage an intermediate solution in which the closing valve 64 and its locking cylinder 65 would be eliminated, the rotor 6c being stiffened by the latches 63, which would preserve the ease of ejection from the sleeve.
- the invention applies in particular to the production of rapid-fire weapons, for example small or medium-caliber.
- the invention applies mainly to the production of machine guns with a rapid rate of fire, in particular for aircraft.
