Definitions

• the present invention relates generally to an explosive charge and particularly, but not exclusively, to a shaped charge.
• the present invention provides a container for an explosive shaped charge, the container is a generally cylindrical bottle-like container and is open at an initiation end, within the container a first membrane is provided to define a proximal enclosure in the container for receiving liquid explosive, a second membrane is provided at or towards the end of the container opposite the initiation end and spaced from the first membrane so as to define a distal enclosure in the container for receiving liquid projectile.
• the second membrane may be generally flat.
• First and second membranes may be formed as nesting components.
• cone members 250, 255 are provided in a nested format, with the second cone member nested inside the first cone member (with the cone apices being axially mutually spaced from each other).
• a liquid explosive material compartment 232 is formed between the first cone member and the neck.
• a liquid projectile material compartment 233 is formed between the two cones members.
• activation of the detonator causes detonation of the liquid explosive material, which in turn causes the water to be projected.
• the liquid explosive may be binary e.g. a sensitizer could be added first and then liquid explosive material.
• the first cone (defining the explosive material compartment/chamber) could be formed as part of the container, or could be provided separately and pre-fitted or fitted at the time of use.
• the second cone could be fitted/secured after filling with projectile material.
• Figures 14 and 15 show a charge 310 formed according to a further embodiment.
• the charge 310 is similar to the charge 210, having a liquid explosive material compartment 332 and a liquid projectile material compartment 333.
• a front membrane 355 has a generally flat profile and an inner cone 350 is provided with a (approximately) 60 degree angle.
• the figures show different variants formed in accordance with the present invention.
• the interlayer/liner/membrane between the explosive and the projectile whether that be a liquid projectile (e.g. water) or a metal (e.g. magnesium) liner.
• Some embodiments therefore allow the production of charges that do not have the projectile in and/or don't have explosive material in; they can be added at an appropriate time. Transport/storage of an empty or partially empty (and not fully enabled) charge container is therefore much safer.
• any sort of projectile could be used/fitted, for example a composite or single material projectile.
