Abstract
A jet cutter venting apparatus and method for venting gases generated during deflagration. The venting apparatus and method including vent grooves inside the jet cutter providing a pathway for deflagration gases to escape. The venting apparatus and method also may include using notches or holes placed inside the jet cutter to facilitate the venting of gases during deflagration. The venting of the gases during deflagration facilitates pressure relief within the jet cutter and increases safety from accidental detonation during a fire.
Claims35
A jet cutter assembly comprising:
- a housing having a wall and at least one vent groove within the wall;
- an explosive material having at least a first explosive surface and a second explosive surface;
- and
- a liner having at least a first liner surface and a first liner rim;
- at least one tamper with an at least one tamper rim;
- wherein the first liner surface is adjacent to the first explosive surface, the second explosive surface is adjacent to the at least one tamper, and the liner rim is adjacent to the wall.
A jet cutter housing adapted to contain explosive material and a liner comprising:
- a closed rigid cross section revolved around a center axis with an inner surface parallel to the center axis;
- at least one tamper with an at least one tamper rim;
- the liner having a liner rim;
- and
- at least one vent groove in the inner surface parallel to the center axis;
- wherein the at least one vent groove is adapted to vent gases from deflagration of the explosive material.
A jet cutter housing adapted to contain an explosive material and a liner comprising:
- a substantially cylindrical portion with an inner wall;
- and
- at least one vent groove in the inner wall of the cylindrical portion.
A jet cutter assembly comprising;
- a first liner having a first liner rim;
- a second liner having a second liner rim;
- a first tamper having a first tamper rim;
- a second tamper having a second tamper rim;
- a first explosive element retained between the first liner and the first tamper;
- a second explosive element retained between the second liner and the second tamper;
- a substantially cylindrical housing having a first inner surface and a second inner surface offset axially, wherein the housing is adapted to contain the first liner, the second liner, the first explosive element, the second explosive element, the first tamper, and the second tamper;
- a plurality of first longitudinal vent grooves in the first inner surface adapted to provide pressure venting around the first liner and first tamper;
- and
- a plurality of second longitudinal vent grooves in the second inner surface adapted to provide pressure venting around the second liner and second tamper.
