Countering the Threat from IEDs

Purpose

Investigating current and emerging
Improvised Explosive Device (IED) threats: 

  • identification of emerging threat
    devices
  • understanding of the physical lethality mechanisms
  • assessment and prediction of the
    on-target eff ects
  • development and assessment of
    physical protection strategies.

Results

  • Design of laboratory reference charges
  • Assessment of real IEDs (roadside bombs, suicide belts, etc. ) against various types of targets
  • Evaluation of impulse for enhanced
    home-made blast charges Mitigation of explosive eff ects: evaluation of COTS systems, new concept evelopment
  • Evaluation of collateral damage generated by urban furniture.

Skills

ISL expertise in terminal ballistics and
detonics: 

  • home-made explosives with enhanced
    blast eff ects
  • IED-EFPs with Explosively Formed
    Projectiles
  • improvised charges with projection
    of fragments
  • both numerical simulations and
    full-scale experiments with real IEDs.


Examples of IED-EFPs

Facilities

  • Detonation bunkers (max. 6 kg TNT)
    with flash X-rays and high-speed imaging
  • Free-field explosion test site with high-speed cameras, pressure and temperature measurements, time resolved pectroscopy
  • Blast bunker with evaluation of the global impulse by lifting an 8-ton roof
  • Terminal ballistics labs equipped with various guns.
