Configuration: Tunnel Geometry

The IED-Protection Device during tests by the german police.

Essential Characteristics

closed system drastically reduced shrapnel dispersion significant reduction of the explosion pressure elimination of the explosion flame compact storage simple manageability and usage easy handling

In the future: shielding of remote detonators removable lateral surfaces

Exemplary fields of application

transport and logistics (airports, train stations etc.) energy sector (power stations, power lines etc.) tourist facilities venues (sport, congresses, conventions etc.) shopping centres, pedestrian areas industry (chemical plants, oil/petroleum depots etc.) health and sanitation (hospitals, purification plants etc.) communication installations police stations, political establishments, security forces

Trials: Experimental Setup

Trials: Explosive Used

1 kg PETN (Nitropenta)

30 Nails 120 x 4 mm

Detonation Velocity:8400 m/s

Explosion Temperature:4200 K

Detonation without Protection Device

Shrapnel effect without Protection Device

Result: significant shrapnel damage

Detonation with Protection Device

Shrapnel effect with Protection Device

Result: no visible shrapnel damage

Explosion Pressure Reduction

Readings provided by: Federal Institute for Materials Researchand Testing (BAM)

Reduction down to 45 % of the pressure without Protection Device.

Variants: Fixed Construction

Variants: Foldable Construction

In folded state the Protection Device fits into the trunk of a passenger car.

Other Systems:Ground Bomb Killer

open at the top expensive (> 20.000 €) low reduction of shrapnel dispersion shielding of remote detonators not possible poor manageability

German Police classification: not effective

Other Systems:Bomb Blankets

simple blanket made of Aramid very low reduction of shrapnel dispersion poor manageability contact with object not avoidable

German Police classification: not effective

Our System:

completely closed system high reduction of shrapnel dispersion significant reduction of the explosion pressure elimination of the explosion flame simple manageability, compact storageablity shielding of remote detonators possible no contact with object

German Police classification: meets all requirements
