Micro Disruption Device



Presented are the results of a study on a miniaturized design based on EFP (Explosively Formed Projectile) as a technical solution for the disruption of specific targets (pressurized pipes, gas cylinders…) with controlled collateral damages. The influence of dimensional factors, such as the liner geometry, the explosive mass and the casing thickness, was assessed by means of numerical simulations. A first series of tests was conducted on simplified surrogate target. The EFP formation was diagnosed by triple exposure flash X-rays. The results led to enhanced numerical models. A final numerical session was carried out to select two designs for the validation phase. This ultimate experimental session combined terminal performance with safety aspects. The study is original in that the mass of the EFP charge is under 6 grams including a liner with a diameter of 3 mm.
