Definitions
- the technical field of the present invention is that of the stabilization means applicable to individual firearms. Any individual and portable weapon is held and oriented towards the target by the hands of the operator who points it in the firing direction with the help of a sighting device generally attached to the barrel. When the weapon is equipped with a sighting device, the sighting direction is materialized by a reticle or any other optical reference.
- an electric firing system is known from filtering gyrometric information, an electric firing system based on image processing and a deviation measurement, and an image stabilization system, for example of a video image, with electric firing.
- the object of the invention is to provide a stabilization system offering a good probability of attack and making it possible to simplify the firing operations, which avoids the drawbacks mentioned above.
- the invention provides a stabilization device for an individual firearm, comprising a sighting device which is characterized in that it comprises means for decoupling the barrel relative to the operator, articulated connection means which are mounted between the barrel and the decoupling means to allow the barrel to pivot relative to the decoupling means, and means for pivoting control of the barrel to compensate for parasitic movements imparted to the weapon by the operator during 'aiming and thus keep the barrel oriented in the direction aimed by the operator.
- the means for decoupling the barrel relative to the operator are constituted by a tubular element which is attached coaxially around the barrel ez secured to the body of the weapon handled by the operator.
- the connecting means mounted between the decoupling means and the barrel comprise two axes of articulation perpendicular to one another and on which the barrel is mounted articulated.
- the connecting means are constituted by a system of the cardan or ball type.
- these connecting means may consist of four sets of wires working in elastic torsion, two sets of wires being respectively located on either side of the barrel and aligned along one of the axes of articulation of the barrel, and the other two sets of wires also being located on either side of the barrel and aligned along the other axis of articulation of the barrel.
- control means for pivoting the barrel and compensating for the parasitic movements imparted to the weapon by the operator during a sighting comprise a servo system which is constituted by:
- control electronics which deliver control signals from instructions provided by two sensors which are integral with the body of the weapon and detect parasitic angular movements of the weapon around the two axes of articulation of the barrel,
- the articulated connecting means which allow the barrel to pivot are located towards the rear of the barrel, while the two actuators which control the pivoting of the barrel are situated towards the front of the barrel ci, the connecting means and the two actuators also serving as support means for the barrel.
- Each actuator is for example constituted by a couoie motor or a geared motor which controls a cam in support on the barrel, and by an elastic return means opposite the cam thus maintaining the barrel aligned with the direction of the target.
- each actuator can be constituted by an electric actuator, an electromagnet or a piezoelectric device.
- the fact of stabilizing the cannon relative to the operator offers in particular the advantage of being able to make the cannon integral with a sighting and telemetry device for ensuring good observation, identification and tracking of targets, as well as '' a good orientation of the telemetry management.
- FIG. 1 is a schematic representation of a weapon equipped with the stabilization device according to the invention
- FIG. 2 represents in the form of a diagram the servo system associated with the stabilization device
- FIG. 3 schematically illustrates an exemplary embodiment of the articulated connection means to allow the barrel to pivot along two perpendicular axes 1 'to one another
- FIG. 1 The portable firearm 1 illustrated in FIG. 1 comprises a body 3 partially shown and which supports all the operating mechanisms of the weapon, a loading and firing chamber 4 extended by a barrel 5.
- the barrel 5 is associated to a stabilization device 10 which comprises means for decoupling 12 of the barrel 5 relative to the operator who handles the weapon 1, articulated connection means 14 which are mounted between the barrel 5 and the decoupling means 12 to allow the barrel 5 to pivot relative to these decoupling means 12, and pivoting control means 15 of the barrel 5 to compensate for parasitic movements printed on the weapon 1 by the operator during a sighting and thus maintain the barrel 5 oriented in the direction aimed by the operator.
- the decoupling means 12 of the barrel 5 relative to the operator are constituted by a tubular element 17 which is attached coaxially around the barrel 5 and secured to the body 3 of the weapon 1.
- the articulated connecting means 14 mounted between the tubular element 18 and the barrel are intended to allow the pivoting of the barrel 5 along two axes X-X, Y-Y perpendicular to each other. These articulated connecting means 14 are located towards the rear of the barrel 5 and are of the cardan or ball type.
- the means for controlling the pivoting of the barrel 5 relative to the tubular element 17 comprise a control system which is constituted by:
- control electronics E which deliver control signals from instructions provided by two sensors C1 and C2 which are integral with the body 3 of the weapon and which detect the parasitic angular movements of the weapon around the two axes of joint XX, YY of barrel 5,
- the two sensors C1 and C2 are of the gyrometric type and carried by a plate 19 secured to the tubular element 17.
- the control electronics ⁇ also supported by the plate 19, include in particular two filters which respectively receive the instructions transmitted by the sensors C1 and C2 to deliver as output the control signals of the two actuators A1 and A.2.
- the two instructions are respectively sent to the two actuators A1 and A2 to rotate the barrel 5 along the two axes of articulation X-X and Y-Y.
- the two actuators A1 and A2 are located towards the front of the barrel 5 and are mounted between the barrel 5 and the tubular element 17 by being arranged along two axes parallel to the two axes of articulation X-X and Y-Y.
- the actuator A1 is constituted by a torque motor 22 or a geared motor which controls a cam 23 which comes to bear on the barrel 5 and by an elastic return means 24, such that 'a spring, to keep the cam resting on the barrel 5.
- the torque motor is a known electric motor delivering a high torque without reduction gear.
- the structure of the actuator A2 is identical to that of the actuator Al.
- the operation of the stabilization device 10 is as follows.
- the control instructions are developed using the two sensors C1 and C2 which measure the parasitic angular movements of the body 3 of the weapon around the two axes of articulation XX, YY of the barrel 5.
- the control electronics E controls the two actuators Al and A2 to cause the barrel 5 to pivot to compensate for the parasitic movements imparted to the weapon 1 by the operator.
- Another servo solution consists in putting angular speed sensors on the barrel, the sensors C3 and C4. In this configuration the sensors C1 and C2 are eliminated.
- the operator aims at his target using the aiming device 26: he places a crosshair on the target.
- the operator can activate the stabilization device (for example using a push button placed on the plate 19). Consequently, the stabilization device becomes operational, that is to say:
- the C3 and C4 sensors measure the angular movements of the gun relative to the terrestrial reference frame and are filtered (high pass filter F1 and F2) to take into account only the tremors but not the movements desired by the operator (in in the case of a moving target) whose frequencies are lower.
- the sensors are preferably gyrometers (angular speed measurement).
- This filtered information is amplified to control the actuators A1 and A2.
- the actuation of the actuators A1 and A2 will be carried out in such a way as to cancel the speed setpoints (filtered) delivered by the sensors C3 and C4.
- the angular velocity sensors Cl and C2 are mounted on the body of the weapon and position sensors are mounted between the body of the weapon and the barrel
- the weapon 1 can be equipped with a sighting and telemetry device 26 which is advantageously carried by the barrel 5 via an arm 27 which passes through an opening 28 made in the tubular element 17.
- the parasitic angular movements of the weapon can reach 3 bn in normal combat situation.
- the firing can be mechanical, since the control is permanent, there remains nevertheless a stabilization residual greater than the measurement accuracy of the sensors (Cl, C2, C3, C4 depending on the solution) due to the imperfections in the control system (inertia, friction, etc.). But by adopting an electric firing, the direct use of the sensor information makes it possible to trigger the firing (electric firing order) at the appropriate time (firing window) hence better precision than mechanical firing.
- FIG 4 there is shown a variant of the articulated connecting means 14 mounted between the barrel 5 and the tubular element 17.
- These means 14 are constituted by four sets of son 17a, 17b working in elastic torsion.
- One end of each set of wires 17a is fixed to the internal wall of the tubular element 17, while the other end is fixed to the external wall of the barrel 5.
- two sets of wires 17a, 17 'a are respectively located on either side of the barrel 5 and aligned along the axis of articulation XX.
- the two other sets of wires 17b, 17'b are respectively located on either side of the barrel 5 and aligned along the axis of articulation Y-Y.
- actuators A1 and A2 Each actuator is constituted by an electric actuator 30, the body of which is carried by the internal wall of the tubular element 17 and the rod of which is articulated on the external wall of the barrel 5.
- the actuators A1 and A2 could be consisting of electromagnets or piezoelectric devices.
