Laser Zentrum Hannover
To be able to safely deactivate unexploded bombs in the future, the Laser Zentrum Hannover e.V. (LZH) is working on a laser-based defusing together with the Laser on Demand GmbH and the Kampfmittelräumdienst Hamburg (KRD). In the DEFLAG project, the project partners LZH and Laser on Demand are working on a procedure to defuse the bombs by targeted deflagration. In contrast to a detonation, a lower pressure wave is created during deflagration and the explosive is converted only to a small extent. For this purpose, the project partners notch the bomb casing with a laser and trigger the deflagration in a second step. In cooperation with the KRD, a field-compatible and automated processing platform is to be created - to safely defuse even dangerous unexploded bombs. Maintaining a critical temperature limit on the lower surface of the material, driving out material from the ablation groove and ensuring process mobility are the crucial issues of this project. Scientists at the LZH have so far been able to notch up to 25 mm thick steel sheets using a combined melting and flame removal process. In doing so, they achieve an ablation depth of up to 16 mm with an external gas supply. At the Hannover Messe, they show processed bomb shells and material samples. The DEFLAG project "Safe Deflagration of Duds by Laser Technology" is being funded by the German Federal Ministry of Education and Research within the scope of the Federal Administrations "Research for Civil Security 2012-2017" program. The fire department Hamburg / bomb disposal team is the Associated Partner.
