Abstract : At the request of the Department of Explosive Disposal of the Royal Netherlands Air Force (AEO-KLu) the possibilities of a modified punching charge has been investigated. The advantage of this concept is that it is flexible; and can be applied in several ways: linear, in a square shape and radial. Based on earlier experience one configuration was chosen: a rubber profile (to focus the shockwave) of 30 deg Shore hardness with a top film, a main charge of plastic explosive (no. 6) and sheet explosive based on RDX (DEMEX 200). With this configuration the minimum and maximum applicable amounts of explosive were determined on one bomb type. It can be concluded that the linear punching charge meets the expectations very well. Multiple linear charges can be successfully applied with a simple adjustment. The square shape is not applicable because of the narrow margins and the time consuming attaching. Radial punching charges can not (yet) be applied either. Used on a bomb with a wall thickness of 9 mm and a filling of cast TNT a minimum charge of 4.2 g/cm is necessary. The maximum charge is determined on 12 g/cm. The margin in between which the punching charge can be applied are to be determined for other types of bombs (different wall thickness and explosive filling)....
