Abstract

A liquid disruptor device and a method of manufacturing the same are introduced. The liquid disruptor device comprises a front casing, a liquid seal film, a rear casing, a plane wave generator and a counter-impact cover. The plane wave generator generates a plane blast wave which compresses a liquid contained in the front casing and a liner to not only focus blast energy of the liquid but also allow the liquid to form a liquid knife current for destroying explosives. Hence, the liquid disruptor device displays higher efficiency per unit weight of explosives when detonation thereof occurs at multiple points. Further, a liquid disruptor device module inclusive of at least two liquid disruptor devices combined to assume a geometric shape is introduced.

Dependent claims

A liquid disruptor device, comprising:

a front casing, comprising:
a liner formed by bending an upright plate lengthwise, backward;
an enclosing wall formed by extending an edge of the liner backward by a distance;
a front casing chamber defined by the liner and the enclosing wall and adapted to contain a liquid;
and
a front casing opening in communication with an outside of the front casing and the front casing chamber;
a liquid seal film for closing the front casing opening of the front casing;
a rear casing coupled to the front casing from behind, the rear casing comprising:
an outer casing wall;
an outer casing wall chamber defined by the outer casing wall and adapted to contain explosives and blowback weights;
an outer casing wall opening in communication with an outside of the rear casing and the outer casing wall chamber;
an inner casing wall disposed in the outer casing wall chamber;
an inner casing wall chamber defined by the inner casing wall and adapted to receive a detonator;
and
an inner casing wall opening in communication with an outside of the rear casing and the inner casing wall chamber;
a plane wave generator disposed between the front casing and the rear casing, the plane wave generator comprising:
a plate having a plate surface and a groove, with the groove disposed on the plate surface and adapted to contain the explosives;
and
a counter-impact cover, comprising:
a lid for closing the outer casing wall opening of the rear casing;
and
a through hole disposed on the lid to penetrate the lid and corresponding in position to the inner casing wall opening of the rear casing.

A method of manufacturing a liquid disruptor device, comprising the steps of:

(a) providing a front casing, the front casing comprising:
a liner formed by bending an upright plate lengthwise, backward;
an enclosing wall formed by extending an edge of the liner backward by a distance;
a front casing chamber defined by the liner and the enclosing wall;
and
a front casing opening in communication with an outside of the front casing and the front casing chamber;
(b) introducing a liquid into the front casing chamber of the front casing;
(c) providing a liquid seal film, followed by closing the front casing opening of the front casing with the liquid seal film;
(d) providing a plane wave generator, the plane wave generator comprising:
a plate having a plate surface and a groove, with the groove formed on the plate surface;
(e) placing explosives in the groove of the plane wave generator, following by placing the plane wave generator behind the front casing;
(f) providing a rear casing, the rear casing comprising:
an outer casing wall;
an outer casing wall chamber defined by the outer casing wall;
an outer casing wall opening in communication with an outside of the rear casing and the outer casing wall chamber;
an inner casing wall disposed in the outer casing wall chamber;
an inner casing wall chamber defined by the inner casing wall;
and
an inner casing wall opening in communication with an outside of the rear casing and the inner casing wall chamber;
(g) placing the explosives and blowback weights in the outer casing wall chamber of the rear casing;
(h) providing a counter-impact cover, the counter-impact cover comprising:
a lid;
and
a through hole formed on the lid to penetrate the lid;
(i) closing the outer casing wall opening of the rear casing with the lid of the counter-impact cover so that the through hole of the counter-impact cover corresponds in position to the inner casing wall opening of the rear casing;
(j) coupling the rear casing to the front casing from behind so that the plane wave generator is disposed between the front casing and the rear casing;
and
(k) inserting a detonator into the inner casing wall chamber of the rear casing.
