An armored vehicle, or battle tank, has a turret, the backplane of which has a hatch allowing access to an inner volume of the turret from the inner volume of the vehicle body. The access hatch has a rectangular-shaped opening and includes a plate for closing up the opening in the form of a plurality of sectors able first to slide in a translational movement in a horizontal movement section and next to be stacked on one another in a vertical stacking section, during the opening of the hatch, the sections being located superimposed in or above the backplane. The access hatch sectors and the backplane include ballistic protection in the form of a metal armor plate covered with an anti-spall coating.

An armoured vehicle turret that can accommodate a crew including a gunner includes: a fixed roof with an opening; a retractable protection system having an armoured cover or dome, that is pivotably movable about a horizontal axis and/or in vertical translation, the retractable protection system being capable of assuming: a first position in which the retractable protection system is retracted against the roof and ensures a closing of the opening; a second partial open position in which the retractable protection system is partially deployed in vertical translation upwards so as to protect a soldier in an observation position; a third partial open position in which the retractable protection system is partially deployed in vertical translation upwards more so than in the second position, so as to protect the soldier in a sniper position; and a fourth fully open position in which the retractable protection system is fully deployed.

A device for distribution of conditioning air for vehicle turret comprises at least one air duct sheath, the sheath comprising a chute adapted to be made integral with the vehicle and a shutter adapted to be made integral with the turret. The sheath is the form of an arch of circle coaxial with the rotation axis of turret. The device comprises at least one duct in the form of an arch of circle having the same average radius as that of the sheath and able to slide with respect to the sheath between a closed position in which the duct connects one end of the sheath to another end of said sheath, or to another sheath, for continuity of airflow between the sheaths, and an open position in which the duct is slid within the sheath so as to leave a passage transverse to the sheath along a circular sector.

In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

An overpressure protection system (30) for a magazine (10) for storing explosive materials. The magazine (10) comprises a wall (12) which defines an internal chamber (14) for housing the explosive materials, with a first aperture (20) defined in the wall (12). The overpressure protection system (30) is configured to close the first aperture (20). The system (30) comprises a burst disc diaphragm (32) for covering the first aperture (20), and a protective cover (34) for locating outside of the chamber (14) and over the burst disc diaphragm (32). The protective cover (34) is spaced apart from the burst disc diaphragm (32) to form a cavity (38) with an opening (36) for venting fluid from the cavity (38).
