Mine and Blast Protection from ABBS

Current blast protection for armoured vehicles is almost universally based on the use of:

  • V shaped hulls
  • High ground clearance
  • High weight
  • High centre of gravity

Unfortunately, this approach has its disadvantages:

  • Instability, leading to poor handling and roll-over accidents.
  • Difficult access from ground level.
  • A larger target.
  • More difficult recovery.
  • Increased weight due to larger surface area to protect.
  • Very heavy fuel consumption

The ABBS approach is to offer mine and blast protection which is based on a flat bottom, which can be fitted onto light armoured and civilian vehicles.

Modified Snatch Land Rover Test Vehicle

This test uses a 6kg TNT Equivalent charge 100mm under the surface of moist soil.

The snatch land-rover is a common light-armoured vehicle and is adapted by the addition of a flat ABBS CRBP (Composite Reinforced Belly Plate) to provide protection against the mine blast; and VGAM™ active countermeasures to prevent Vehicle Global Acceleration and ensure that the vehicle remains on the ground.

The VAFS™ (Active Floor system) ensures that the floor is pulled away from the vehicle occupants in order to prevent transmission of shock into the lower limbs.

The test rig is set with the ABBS belly plate at 300mm above soil surface.

The following technologies can then be seen in action:

  • CRBP  (Composite Reinforced Belly Plate) the addition of composite beams to a flat steel belly plate minimises deformation and reduces impulse transferred to the vehicle.  This forms a passive belly plate with 15mm Hardox 450 main plate. The CRBP minimises deformation, prevents contact with floor and fragment penetration.
  • VGAM™ function – two 7kNs LRM™ countermeasures which eliminate G-load injuries – 100kg system weight.
  • EFI initiator runs in safe mode, unpowered until sensor/control system recognises a mine blast requiring a response..
  • VAFS™ (Vehicle Active Floor System) prevents lower limb injuries due to floor shock – 10kg system weight

We used various instruments to measure the results:

  • Hybrid III secured in Jankel Mk 3 Crew Seat
  • DRI Device – Direct mechanical measurement of dynamic response index in standard Snatch driver’s (non-blast) seat.
  • Accelerometers and LVDTs into off-board data acquisition system
  • Blast Gauge system sensors around ATD at head and chest height.
  • Five High-Speed Video Cameras

The Final Result following the test using ABBS Mine and Blast Protection Systems

Driver’s door closed and latched normally after test.

No significant body distortion

The composite beam structure was intact and the Hardox 450 faceplate showed only 30mm indentation above charge and no penetration.

The standard driver’s seat measured only DRI 16 (below the injury threshold)

Jump height limited to only 0.3 metres.

How can the ABBS Mine and Blast Protection System Benefit You?

We continue to work with the US Army and the UK MOD on development and proving the system, and welcome further enquiries from armed vehicle manufacturers around the globe.

The latest version of the ABBS CRBP passive belly plate design has shown that not only can this be used as a flat belly plate to provide protection for civilians and aid agencies working in former war zones, but it is also potentially suitable as an upgrade for existing MRAP V-hulls.

As an upgrade, to V-hulls, the energy absorbing  technologies of the CRBP can mitigate the initial peak shockwave loads and increase blast capability to a level above what exists already.  This would result in only a 50mm decrease in ground clearance and fairly insignificant weight addition.

Shock transfer into the main vehicle structure should be reduced as well as making it less likely that belly plate failure will occur due to the peak loading.
