a plurality of frames disposed within the housing, wherein each frame of the plurality of frames has a central axis and a plurality of liners, wherein each frame of the plurality of frames is axially aligned, and wherein each liner of the plurality of liners is configured to secure a respective wireless shaped charge of the one or more wireless shaped charges, wherein each frame of the plurality of frames comprises a central passage and an electrical conductor disposed in the central passage;
a capsule configured to provide an ignition source for the one or more wireless shaped charges, wherein the capsule is disposed within the electrical conductor;
an initiator module disposed in the housing; and
a bulkhead member disposed in the housing and forming a seal with the housing, wherein the bulkhead member is disposed in the housing separating the initiator module from each frame of the plurality of frames within the housing.
8. The perforation tool of claim 7 , wherein the bulkhead member has an additional central passage, and an additional electrical conductor disposed in the additional central passage.
9. The perforation tool of claim 8 , wherein the bulkhead member has an insulating member disposed in the additional central passage, and wherein the additional electrical conductor disposed in the additional central passage is within the insulating member.
10. The perforation tool of claim 7 , wherein an outer surface of the electrical conductor contacts an inner surface of the central passage.
11. The perforation tool of claim 7 , wherein a first frame of the plurality of frames has a first central passage, a second frame of the plurality of frames has a second central passage, and the second frame is ballistically coupled to the initiator module via the second central passage.
12. The perforation tool of claim 7 , wherein a first liner of the plurality of liners is configured to orient a first shaped charge in a first direction, and wherein a second liner of the plurality of liners is configured to orient a second shaped charge in a second direction different than the first direction.
13. A perforation tool, comprising:
a housing;
a plurality of frames disposed within the housing, wherein each frame of the plurality of frames has a central axis and a plurality of liners, wherein each frame of the plurality of frames is axially aligned, wherein a first liner of the plurality of liners is configured to orient a first shaped charge in a first direction, and wherein a second liner of the plurality of liners is configured to orient a second shaped charge in a second direction different than the first direction, wherein each frame of the plurality of frames comprises a central passage and an electrical conductor disposed in the central passage;
