Abstract
A simulated improvised explosive device has a cylindrical outer casing and a cylindrical inner casing received within the outer casing to define an annular first passage between the inner and outer casings and a second passage within the inner casing. A charge holder supports a charge at a first end of the second passage. The second ends of the inner and outer passages communicate with one another opposite from the charge holder. Exhaust ports are located at the first end of the first passage so that the expelled gases from detonating the charge are directed substantially along a full length of both passages. A flow restriction is provided within the first passage to assist in containing sparks within the outer casing rather than be expelled from the exhaust ports.
Claims12
A simulated explosive device for use with a pyrotechnic charge, the device comprising:
- an outer casing extending in a longitudinal direction between a first end and a second end of the outer casing;
- a first exhaust passage defined within the outer casing to extend in the longitudinal direction between a first end of the first exhaust passage in proximity to the first end of the outer casing and a second end of the first exhaust passage in proximity to the second end of the outer casing;
- an inner casing supported within the outer casing to extend in the longitudinal direction between a first end and a second end of the inner casing;
- a second exhaust passage defined within the inner casing to extend in the longitudinal direction between a first end of the second exhaust passage in proximity to the first end of the inner casing and a second end of the second exhaust passage in proximity to the second end of the inner casing;
- a charge holder supported at the first end of the second exhaust passage so as to be arranged to support the pyrotechnic charge in communication with the first end of the second exhaust passage;
- at least one intermediate port in communication between the second end of the second exhaust passage and the second end of the first exhaust passage;
- at least one exhaust port in communication from the first exhaust passage to an exterior of the outer casing;
- said at least one exhaust port being in proximity to the first end of the first exhaust passage.
