Definitions

  • the present invention is related to a lightweight armour module, in particular, a stand- off armour module for a vehicle or similar object.
  • the invention further relates to an arrangement of such modules and a vehicle comprising such armour.
  • Rocket Propelled Grenades are one form of weapon used by armies and also by terrorist groups to target military objects. In some countries they can be acquired relatively easily and yet are highly effective against even the most heavily armoured targets.
  • An RPG is generally shoulder fired from a launcher and flying at a maximum speed of around 300 m/s can hit a target at up to 1000m.
  • a contact fuse on the nose of the grenade causes an explosive charge to extrude a rapier like jet of copper through the nose cone.
  • this is capable of piercing in excess of 350 mm of steel plating and causing significant devastation thereafter - a phenomenon known as Behind Armour Effect.
  • a vehicle protected using steel plate alone, would therefore be extremely heavy, bulky and difficult to move.
  • additional armour concepts have been combined, capable of defeating different forms of weapon.
  • Armour systems designed for the defeat of RPGs often take the form of bar-shaped armour structures arranged at a certain distance or stand-off from the target or vehicle.
  • the stand-off distance is usually greater than 30 cm.
  • This bar-armour usually consists of a rigid array of steel or aluminium bars arranged in a relatively horizontal direction with vertical stabilizing elements. The spacing between the bars is such that an RPG will not be able to pass through and directly strike the body of the vehicle. Effective detonation of the explosive charge is thus avoided..
  • the deformation of the nose cone by the bar-armour should be sufficient to prevent effective initiation of the armour penetrating rapier. In combination with such bar-armour a relatively thinner form of plate armour may suffice.
  • the bar armour Due to its bulky nature and the additional vehicle width, the bar armour is also often the first part of a vehicle to contact an obstacle and for this reason is frequently damaged.
  • the robust nature of the fixed brackets for supporting bar-armour renders each bar- shaped armour module highly bulky and presents a logistical challenge for the transport of new or replacement panels which weigh little but take up a high volume of space. Normally the space requirement within a transport aircraft or vehicle is of greater concern to military operations than the weight.
  • US patent 7882776 discloses armour for a vehicle comprising a grid of horizontal carbon fibre bars arranged in slots formed in vertical metallic bars.
  • the structure is relatively lighter than a corresponding metal structure but nevertheless may be prone to damage and distortion due to the rigid nature of the grid.
  • EP2265889 Al discloses a vehicle and structure shield comprising a flexible net system carried by a frame with mounting brackets for positioning the frame at a stand-off from the vehicle.
  • a releasable fastener system such as hook and loop fasteners may be used for securing the net system to the frame and for securing the mounting brackets of the frame to the vehicle.
  • an armour module for a vehicle comprises a plurality of flexible vertical elements to be arranged substantially parallel to each other in a substantially vertical direction; a plurality of horizontal slats to be arranged substantially parallel to each other in a substantially horizontal direction; and a connection arrangement for supporting the armour module in a stand-off relation to the vehicle.
  • the use of flexible vertical elements in combination with horizontal slats provides a flexible, lightweight armour module that may be easy-to-store, easy-to-use and easy-to- replace.
  • a vehicle is intended to denote that the armour is suitable for being mounted to a vehicle such as a road vehicle, off-road vehicle, tank, boat, or even an aircraft such as a helicopter.
  • the same principle may be applied to fixed or semi-mobile structures such as armoured placements, observation platforms or the like.
  • vertical and horizontal elements it will be understood that such orientation is relative and not otherwise essential and that the armour module may be mounted at any angle with respect to the object which it protects.
  • the slats are also flexible, at least in a direction perpendicular to a plane of the slat. Preferably they have a flexural modulus of between 10 GPa and 200 GPa. The degree of flexibility may be adapted such that adjacent slats will not spread apart on impact to allow an RPG to pass through. The resulting module is thus flexible in multiple directions and may also be twisted without damage.
  • the slats are preferably made of composite material, in particular, glass or carbon-fibre reinforced materials including, but not limited to polyester, vinylester, PPS, PET and epoxy resins. By use of lightweight materials an areal density of the armour module of less than 25 kg/m 2 may be achieved.
  • the degree of flexibility may also determine the spacing of the vertical elements.
  • a highly rigid carbon fibre slat having a flexural modulus close to 200GPa may require relatively few vertical elements. Glass fibre slats are more compliant , and may have a flexural modulus of around 20GPa. In that case a closer spacing of the vertical elements may be desirable.
  • the term "slat” is intended to denote a relatively elongate element having a width and a relatively low profile or height, at least at a leading edge i.e. the side of the slat directed away from the vehicle and facing towards an oncoming projectile. In general such slats may be rectangular in cross- section although other shapes may be considered including triangular or curved shapes.
  • the slats have a width of between 4 cm and 10 cm, preferably around 5 cm.
  • the height of the profile at the leading edge is preferably less than 10 mm.
  • the slats will be straight although it will be understood that they may also be provided with complex shapes e.g. to match the body to which they are applied. In particular, for protecting a corner of an object, a hockey-stick shaped slat may be provided.
  • the spacing between adjacent slats should be sufficient to prevent an PvPG from passing through.
  • a spacing of from 3 cm to 8 cm is desirable, preferably between 4 cm and 6 cm and most preferably around 5 cm.
  • the vertical elements may extend through openings in the horizontal slats.
  • Such a structure is relatively simple to manufacture.
  • the vertical elements may be aligned with one another but may also be offset to different positions within the width of the slats. In this manner, the stability of the module may be adapted according to the degree of offset. It will be understood that as the offset of the vertical elements is increased, the ability to roll up the module is reduced.
  • a plurality of fastening elements may fasten the horizontal slats and vertical elements together. These may comprise crimps, clips, swages or the like applied to the vertical elements which serve to engage the horizontal slats.
  • the fastening elements may comprise flexible provisions that allow the horizontal slats limited movement with respect to the vertical elements. This relative movement may be vertical, horizontal, lateral or torsional and may increase the overall flexibility of the structure and assist in allowing the armour module to be rolled, folded or otherwise packed.
  • the flexible provisions may comprise appropriate gaps and may also include resilient washers and packings allowing such relative movement.
  • the slats may be fastened to each other and the vertical elements may e.g.
  • the vertical elements comprise steel cable of an appropriate gauge. For most purposes, cable gauges of from 4 mm to 12 mm may be sufficient, preferably around 6 mm.
  • the slats may be arranged to lie flat i.e. in a horizontal plane. Nevertheless, the slats may also be tilted upwards or downwards in the manner of Venetian blinds. This may further assist in deflecting or distorting an incoming RPG.
  • the slats comprise interconnections at their ends for connection to the slats of an adjacent armour module.
  • the interconnections may take various forms and may be provided by ancillary clips or connectors.
  • the slats may be provided with further openings near their ends through which a cable or the like may be threaded to retain both sets of slats together.
  • the invention also provides for a vehicle provided with one or more armour modules as described above.
  • Each armour module may be connected to an adjacent armour module by interconnections between ends of the slats.
  • stand-off armour for a vehicle comprising a flexible protecting element and one or more supports for securing the protecting element to the vehicle, wherein the supports are resilient and capable of being deformed in response to deformation of the protecting element and thereafter returning to a stand-off position.
  • Such an arrangement reduces damage to the vehicle or supports due to impact on the protecting element and furthermore allows the flexible protecting element to more adequately function.
  • the resiliency of the supports is such that they may deform e.g. in response to collision with an object during driving of the vehicle. It is not intended that they should significantly deform in response to impact by an RPG on the protecting element.
  • the protecting element may be as defined above although the skilled person will be aware that the use of resilient supports is not limited to slat based structures.
  • the supports comprise upper brackets from which an upper side of the protecting element is suspended.
  • the upper brackets support the weight of the protecting element and may provide the primary point of retention on the vehicle.
  • the upper brackets may themselves be resilient or may comprise rigid members connected together by flexible means such as resilient suspension blocks.
  • the supports further comprise one or more tensioning elements, arranged to apply a tension to a lower side of the protecting element.
  • the tensioning elements may comprise struts which may be biased in a bending mode to tension the protecting element and maintain the stand-off between the vehicle and the protecting element.
  • the struts may be formed of steel, aluminium, polymer or composite materials, preferably of fibre reinforced composites.
  • the supports may also be stowable, allowing the armour module to be retracted against the vehicle body for transportation purposes or to pass through a narrow space.
  • the supports may also be arranged to retract or fold flat against the vehicle structure when the armour module has been removed.
