Abstract

A plurality of embodiments of disruptor all have a container with an enclosure for explosive material with a wall which can he located in any one of a number of different positions using one or more tubular spacers (12) optionally of various sizes thereby to provide a wide range of capacity of enclosure and hence explosive material.

Claims

1. A single-use disruptor including an explosive charge, the disruptor comprising a container for a projectile and explosive material, the disruptor and container for destruction in its single-use after detonation of the explosive material, the container comprising:

an enclosure for holding explosive material, said enclosure having a wall of the projectile locatable at any one of a number of positions defining the capacity of said enclosure for explosive material, and one or more spacer elements to hold the wall in one position and so define the enclosure, wherein the one or more of the spacer elements are provided in the container but outside the enclosure.

2. A single-use disruptor according to claim 1 wherein one or more of the spacer elements are provided in the enclosure.

5. A single-use disruptor according to claim 1 wherein the projectile further comprises the one or more spacer elements.

6. A single-use disruptor according to claim 1 wherein the projectile is of one of the following shapes:

(i) a cone form;

(ii) a flat disc;

(iii) a radially symmetric body provided with a spherical, hyperbolic or other concavity;

(iv) a wedge of V-shaped section.

7. A single-use disruptor according to claim 1 wherein the projectile is made of one of the following materials:

(i) magnesium;

(ii) zirconium;

(iii) titanium.

8. A kit of parts for a disruptor according to claim 1, the kit of parts including a container for a disruptor, a projectile, an enclosure for holding explosive material having a wall of the projectile locatable at anyone of a number of positions thereby to define the capacity of said enclosure.

9. A single-use disruptor according to claim 1, wherein the enclosure comprises a detonator disposed in said enclosure for detonating said disruptor.

3. A single-use disruptor including an explosive charge, the disruptor comprising a container for a projectile and explosive material, the disruptor and container for destruction in its single-use after detonation of the explosive material, the container comprising:

an enclosure for holding explosive material, said enclosure having a wall of the projectile locatable at any one of a number of positions defining the capacity of said enclosure for explosive material, and one or more spacer elements of annular form to hold the wall in one position and so define the enclosure.

4. A single-use disruptor including an explosive charge, the disruptor comprising a container for a projectile and explosive material, the disruptor and container for destruction in its single-use after detonation of the explosive material, the container comprising:

an enclosure for holding explosive material, said enclosure having a wall of the projectile locatable at any one of a number of positions defining the capacity of said enclosure for explosive material; and

one or more spacer elements to hold the wall in one position and so define the enclosure, wherein at least one of the one or more spacer elements comprises a hollow compartment for water or other filler material.

10. A single-use disruptor including an explosive charge, the disruptor comprising a container for a projectile and explosive material, the disruptor and container for destruction in its single-use after detonation of the explosive material, the container comprising:

an enclosure for holding explosive material, said enclosure having a wall of the projectile locatable at any one of a number of positions defining the capacity of said enclosure for explosive material; and

a consolidating ring that engages with a first end of the container;

an explosive material disposed in the container; and

a projectile positioned in the container by the consolidating ring at any one of any number of positions to form an enclosure for the explosive material, wherein the projectile is axially aligned with an axis of the container by the consolidating ring and wherein a wall of the projectile is urged against the explosive material.

11. The single-use disruptor of claim 10, further comprising one or more spacer elements to hold the wall in a particular position.

12. The single-use disruptor of claim 10, further comprising a nozzle connected to the consolidating ring, wherein the nozzle collimates the projectile.

13. The single-use disruptor of claim 10, further comprising water positioned between the projectile and the explosive material.
