DETAILED DESCRIPTION OF THE INVENTION

[0013] With reference to the accompanying figures, number 10 indicates, as a whole, a turret manufactured according to an explanatory embodiment of the present invention.

[0014] With particular reference to FIGS. 1 and 2, the turret 10 comprises a support assembly 12, which is configured to support and move a firearm 14 about an azimuthal rotation or swivelling axis Y (which is substantially vertical) and about a zenithal rotation or elevation axis X (which is substantially horizontal). These axes are schematically shown in FIG. 1.

[0015] In particular, the support assembly 12 has an outer shape known as stealth, which permits a reduction of the reflection of electromagnetic waves, so as to reduce the radar track of the turret.

[0016] In the embodiment shown herein, the firearm 14 is configured to shoot guided munitions. Said firearm 14 preferably has a stealth cover 15, which externally surrounds its barrel and has a shape that permits a reduction of the reflection of electromagnetic waves, so as to further reduce the radar track of the turret.

[0017] The support assembly 12 comprises a base 16, which is configured to be fixed to a fixed part (e.g. the upper deck of a ship, by means of a suitable interface), a swivelling mass or structure 18, which is supported by the base 16 in its rotation about the swivelling axis Y, and a pivoting mass or structure 20, which is supported by the swivelling structure in its rotation about the elevation axis X.

[0018] In the embodiment shown herein, the firearm 14 is mounted so as to be integral to the pivoting structure 20 in its movements, so that it is capable of simultaneously being integral to the swivelling structure 18 in its rotation about the swivelling axis Y and integral to the pivoting structure 20 in its rotation about the elevation axis X.

[0019] As you can see, in particular, in FIGS. 3, 4 and 5, the turret 19 further comprises a munition guiding device 22, which is configured to direct a precision-guided munition, which is shot by the firearm 14 towards a target, for example through the emission of a radio wave follower beam, for example a laser beam. In particular, the munition guiding device 22 can cooperate with an external radar device (not shown), which is configured to determine the positionand, optionally, the speedof a stationary or moving target, such as an aircraft.

[0020] In particular the external radar device preferably is configured to detect data indicating the position of the target, such as the azimuthal angle, the height and the distance relative to a reference point. More preferably, the munition guiding device 22 is also configured to detect data indicating the speed of the target, thus providing a predictive estimation of the trajectory followed by the target.

[0021] In the embodiment shown herein, the munition guiding device 22 is configured to orient and emit the follower beam towards the target based on the indicating data detected by the external radar. By so doing, the munition shot through the barrel of the firearm 14 is capable of following the target through a built-in electronic system, which follows the follower beam.

[0022] The turret 10 further comprises a protection apparatus 24, which is mounted on the support assembly 12 and is configured to assume a covering condition (FIGS. 1 and 2), in which it hides the munition guiding device 22 on the inside of said support assembly 12, and an opening condition (FIGS. 4 and 5), in it shows the munition guiding device 22 on the outside of the support assembly 12.

[0023] By way of example, FIG. 3 shows the transition between the covering condition and the opening condition of the protection apparatus 24. More in detail, in the turret 10 shown in the top part of the figure, said protection apparatus 24 is in the covering condition. On the other hand, in the turret 10 shown in the top bottom of the figure, said protection apparatus 24 is in the opening condition.

[0024] The covering condition typically takes place when the turret 10 is not operating, namely when the firearm 14 is not used to shoot against a stationary or moving target. In this way, in case of a sudden attack carried out by an external source of threat, the munition guiding device 22 is hidden and remains completely concealed on the inside of the support structure 12 of the turret 10. Therefore, in this condition, thanks to the protection apparatus 24, the integrity of the munition guiding device 22 is preserved in case of impact with missiles, further reducing its traceability through radar.

[0025] Vice versa, the opening condition usually takes place when the turret 10 is operating, namely when the firearm 14 is used to shoot against a stationary or moving target. In this way, the munition guiding device 22 can be aimed at the space outside the turret 10 so as to allow it to detect the position and/or speed of a target to be hit with the firearm 14.

[0026] In the embodiment shown herein, the munition guiding device 22 is integral to the pivoting structure 20 in its rotation, so as to rotate with it in an integral manner about the elevation axis X. In particular, the firearm 14 and the munition guiding device 22 are rotary about the elevation axis X.

[0027] In the embodiment shown herein, the munition guiding device 22 is movable relative to the pivoting structure 20. For example, the munition guiding device 22 is supported by the pivoting structure 20 with a freedom of azimuthal rotation and/or zenithal elevation relative to the pivoting structure 20, so as to allow the beam to be oriented in the space in order to direct the munitions. Advantageously, the munition guiding device 22 is located under the barrel of the firearm 14. In the embodiment shown herein, the protection apparatus 24 is mounted on the swivelling structure 18 in a front portion, namely a position from which the firearm 14 and the munition guiding device 22 are destined to project. However, in alternative embodiments, the protection apparatus can also be mounted on the pivoting structure.

[0028] Preferably, the protection apparatus 24 comprises a shield located in a front part of the support assembly 12 (in the embodiment shown herein, it is located in the front part of the swivelling structure 18). As already mentioned above, the shield can be moved between the covering condition and the opening condition.

[0029] Advantageously, though not necessarily, the shield comprises a pair of doors 26, which are hinged on a front wall of the support assembly 12. In the embodiment shown herein, the pair of doors 26 are hinged to the swivelling structure 18. However, in further embodiments of the present invention, it is possible to create said shield by adopting only one of said doors or even by using shields of a different type (for example, with one or more doors that slide in a guided manner on the support structure 12).

[0030] In the embodiment shown herein, the movement of the shield between the covering condition, corresponding to a closed position of the doors 26, and the opening condition, corresponding to a completely open position of said doors 26, is of the type with leafs capable of pivoting outwards from the support structure 12.

[0031] Preferably, though not necessarily, in the covering condition the ends of the doors 26 rest against one another so as to form a front corner indicated with 27 in FIG. 3. Hence, when the doors 26 are in the covering condition, the protection apparatus 24 has, at the front, a corner-like profile, which helps hide the munition guiding device 22 with a stealth shape, thus reducing the radar track of the turret.

[0032] In particular, the swivelling structure 18 defines a central compartment 28 (better visible in FIG. 5), through which the pivoting structure 20carrying the firearm 14 and the munition guiding device 22is mounted with freedom of movement about the elevation axis X and supported by a proper carriage.

[0033] When the doors 26 are in the opening condition, the munition guiding device 22 faces outwards from the swivelling structure 18 through the central compartment 28. In particular, the doors 26 are hinged in the area of the edges that laterally delimit the central compartment 28. In the embodiment shown herein, the doors 26 are configured to pivot outwards from the swivelling structure 18, so as to open.

[0034] Preferably, the doors 26 are configured to pivot into the opening condition (completely open condition) about a substantially vertical hinging axis when the turret 10 is operatively mounted on a fixed part (by way of example, on the upper deck of a ship).

[0035] In the embodiment shown herein, the pivoting structure is capable of assuming a storaging position, in which the munition guiding device 22 is completely contained in the shapes of the swivelling structure 18. In this storing position, the doors 26 of the protection apparatus 24 are capable of moving from the opening condition to the closing condition. In particular, the storing position assumed by the pivoting structure 20 corresponds to a substantially horizontal orientation of the firearm 14, namely an orientation in which the elevation of said firearm 14 is substantially equal to 0?. In the embodiment shown herein, when the pivoting structure 20 is angularly spaced apart from the storing position, the doors 26 would not be able to close, as they would strike against the device 22 or the rest of the pivoting structure 20, which would project beyond the shape defined by the swivelling structure 18.

[0036] In the embodiment shown herein, the doors 26 can be moved by an actuator apparatus, for example one or more electric motors.

[0037] By way of example, the doors 26 are made of a metal material (e.g. steel). Preferably, the turret 10 comprises a control system, which is configured to control the movement of the protection apparatus 24 (in particular the doors 26) between the covering condition and the opening condition, for example by means of the actuator apparatus mentioned above. The control system can, more preferably, have a manual operating mode to cause the movement of the doors 26, which turns out to be useful, in particular, in emergency condition or, anyway, any time the automatic operation cannot be used.

[0038] Furthermore, the above-mentioned control system is configured to control the movement of the swivelling structure 18 and the movement of the pivoting structure 20, independently of one another, so as to obtain the orientation of the firearm 14 according to the desired shooting line. In particular, the control system can be configured to automatically determine the desired shooting line and to control said movements accordingly, based on the position and/or speed data of a target acquired by the radar device and depending on the operation of the munition guiding device 22, according to predetermined criteria.

[0039] Hereinafter you can find a description of an explanatory operating mode of the turret 10.

[0040] Let's consider the movement from a rest configuration to an operating configuration of the turret 10, in which the firearm 14 is destined to be operated so as to shoot against a stationary o moving target.

[0041] During this movement, at first the doors 26 are moved from the covering condition to the opening condition. By so doing, the munition guiding device 22 is shown on the outside of the support structure 12, so that it can emit a radio wave follower beam towards the target, for example depending on the data concerning the positionand optionally the speedassumed by a stationary or moving target, which is going to be shot at by means of the firearm 14. As already mentioned above, said data can be detected by an external radar device.

[0042] Furthermore, the movement of the protection apparatus from the covering condition to the opening condition preferably allows the pivoting structure 20 to rotate about the elevation axis X. As a matter of fact, in the embodiment shown herein, should the doors 26 be in the covering condition (closing position), the movement of the pivoting structure 20 would be hindered by doors 26 themselves, which would cover the opening 28.

[0043] After the protection apparatus 24 has moved to the opening condition, the control system causes, independently of one another: [0044] the movement of the swivelling structure 18 relative to the base 16 about the azimuthal rotation or swivelling axis Y, and [0045] the movement of the pivoting structure 20 relative to the swivelling structure 18 about the zenithal rotation or elevation axis X.

[0046] These movements allow the firearm 14 to take on an orientation corresponding to a desired shooting line, so as to shoot a stationary or moving target.

[0047] The control of the two aforesaid movements through the control system can be carried out: [0048] automatically by means of predetermined criteria and based on the orientation of the emission of the radio wave follower beam carried out by the munition guiding device 22 and/or on position and/or speed data detected by the radar device, and/or [0049] manually by a user through known interfaces.

[0050] Naturally, the principle of the invention being set forth, embodiments and implementation details can be widely changed relative to what described above and shown in the drawings as a mere way of non-limiting example, without in this way going beyond the scope of protection provided by the accompanying claims.
