The technical field of 1 invention is that the blast deflectors for military vehicles and military vehicles fitted with such baffles.
Military vehicles often include superstructure facilities that are vulnerable to blast generated by the firing of an onboard cannon whose mouth is in the vicinity of such equipment.
It is known to address this vulnerability to dismantle the said equipment during periods of prolonged shooting with the weapon and reassembly during operations movement.

Is also known from patent US6302010 a shield intended to be fixed on the roof of a vehicle and having three hinged panels. A central panel is hinged on the vehicle roof and two side panels are hinged to the center panel. This shield is designed to protect a manhole, not a superstructure equipment. The side panels must be handled by an operator and the establishment of such a shield remains difficult and requires the presence of an operator to position the side panels.

The invention proposes to resolve this vulnerability by providing a breath deflector that protects the equipment during the use of the weapon and which can be easily set up to ensure the protection of 1 equipment.

Advantageously, the invention does not strike the volume of evolution of the equipment outside of the barrel using phases or oppose significantly to the advancement of the vehicle during the phases of movement. Equally advantageously, the invention does not impact the operation of the protected equipment.

Thus the invention relates to a blast deflector for military vehicle comprising a central panel contiguous with two side panels disposed on either side of the central panel, deflector characterized in that the panels can be tilted between a raised position suitable for deflecting breath and a lower position where the panels are substantially horizontal, the central panel being hinged to the vehicle by means of an articulation located on a lower edge of the central panel, each side panel being hinged to a lateral edge of the panel central by means of a hinge, an actuator connecting the central panel to the vehicle and thus controlling the movement of lowering or raising of the central panel,each side panel comprising a guide rod on which a sliding bearing is adapted to slide and rotate, each bearing being connected to the actuator by a rod which makes it possible, when the central panel is lowered, lowering by driving the panels side while avoiding the central panel in order to place all the panels in the same substantially horizontal plane once lowered and vice versa can raise all panels simultaneously giving them an angular disposition relative to each other to form a protective shell against the breath.lowering by drive side while avoiding the panels of the central panel in order to place all the panels in the same plane substantially horizontal once lowered and vice versa can raise all panels simultaneously giving them an angular disposition relative to each other to form a protective shell against blast.lowering by drive side while avoiding the panels of the central panel in order to place all the panels in the same plane substantially horizontal once lowered and vice versa can raise all panels simultaneously giving them an angular disposition relative to each other to form a protective shell against blast.

Advantageously, the central panel is articulated with respect to a fixed lower part comprising three contiguous facets having an angular disposition relative to each other the same as that of the panels in a raised position to form a protective shell against blast.

Advantageously, the actuator is a hydraulic cylinder.

Advantageously, each panel comprises at least one strut comprising a nestable shape for mating with a corresponding complementary shape located on the vehicle or the lower part in order to transmit the forces of the wind received by the panels.

The invention also relates to a military vehicle having an artillery gun having a deflector according to the characteristics mentioned above, baffle for protecting a superstructure element of the vehicle in the vicinity of the muzzle so that, when the artillery is lowered, the panels are placed in the lower position above the mouth of the barrel, and that, when the gun is pointed, the protective shell deflects the blowing directed towards the superstructure element.

Advantageously, the superstructure element includes a close protection weapon.

The invention will be better understood from reading the following description, description with reference to the accompanying drawings, drawings in which:

1 shows a three-quarter view of a vehicle according to the invention.

2 shows a view of the invention in raised position.

Figure 3 shows a rear view of the invention in the intermediate position.

4 shows a view of the invention in the lowered position.

5 shows a side view of the invention in the lowered position.

According to Figure 1, a military vehicle 100 has a barrel 101 artillery pointed and ready to fire. The vehicle 100 also comprises a device 102 superstructure. This equipment 102 here comprises a remotely-operated gun 102 to the close protection of the vehicle 100. This device 102 is in the path of the wave mouth 103 of consecutive barrel shooting. This wave mouth 103 is formed by the propulsive gases exiting the muzzle brake 17 as a result of the projectile. The wind 103 is likely to damage the equipment 102 by the sudden overpressure. A deflector 1 is here raised position and protects the device 102 against blast 103 emitted by the artillery during firing by deflection of the breath on the exterior surface of panels 2 and 3 that comprises one deflector.

According to Figure 2, deflector 1 comprises a central panel 2 adjacent to two side panels 3 disposed on either side of the central panel, side panels also visible in Figure 1. The deflector 1 is in a raised position suitable for deflecting the breath through the shell-shaped part enveloping the equipment 102 to be protected.

According to a preferred embodiment, seen in FIGS 1-5, the central panel 2 is hinged to a lower portion 9 having three facets 9a, 9b, 9c contiguous having a relative angular disposition between facets 9a 9b, 9c which is identical the angular disposition of the panels 2 and 3 in the raised position, so as to contribute to form a lower part of the protective shell against blast. This lower part 9 allows to raise the deflector 1 and comprises legs forces 11 (Figure 3) able to absorb the forces transmitted by the panels 2 and 3 in the raised position.

As seen in Figure 3, the central panel 2 is hinged to the lower part 9 by means of a hinge 4 located at a lower edge of the central panel 2. Each side panel 3 is hinged to a lateral edge of central panel 2 by means of at least one hinge 5. an actuator 6, in this case a hydraulic or electric jack connects the central panel 2 to the lower part 9 and thus control the movement of lowering or raising deflector 1 .

Each side panel 3 has a guide rod 7 disposed obliquely with respect to the outlet direction of the cylinder rod 6, rod 7 on which a smooth bearing 8 is able to slide and rotate. Each bearing 8 is connected to the cylinder 6 by a connecting rod 12 which is pivotally mounted relative to the cylinder 6 at joints 15 parallel to the piston rod 6.

Ainsi, lorsque the central panel 2 s'abaisse, the Hose by teak les panneaux latéraux 3 en tout les écartant of him.

In the lowered position, the panel 2 is placed rearward of the vehicle in a substantially horizontal plane P and visible in Figures 4 and 5 and the side panels 3 are arranged on either side of the central panel and substantially in the same horizontal plane P.

Conversely, to close the lowered position of Figure 4, the retraction of the rod of the actuator 6 allows to meet simultaneously all the panels 2 and 3 by sliding bearings 8 along the rods 7 thereby providing a relative angular disposition between the panels 2 and 3 adapted to reform a protective shell against the breath once the panels revenue raised position.

According to Figure 5, lower panels 2 and 3 makes it possible to give the possibility to the device 102 to have a full travel azimuth of 360 degrees and to allow it a certain deflection in negative site.

Furthermore, setting the lowered position of the panels 2 and 3 limit the windage of the deflector 1, thereby reducing the efforts to the advancement of the vehicle during transport phases.

Moreover the fact of lowering the deflector 1 on a low part 9 having a height allows the panels 2 and 3 to be positioned over the muzzle of the barrel 100 when the latter is lowered vicinity of the cabin 16 of the vehicle, for example during the transport phase.

If it is not necessary to lower the gun and in the vicinity of the cabin 16 of the vehicle, the lower part 9 is not essential and the deflector 1 can be directly secured to the vehicle cabin.
