Pyrotechnic launch units and systems

A pyrotechnic launch unit comprising:

• an elbow module (110) including
• a launch barrel (116),
• an elbow passage (110a) in communication with the launch barrel, and
• a coupling tube (148) in communication with the elbow passage;
• a first module (130) coupled to the elbow module, the first module including
• an output passage (132j) in communication with the coupling tube,
• a first slide member (138) including a first pass-through bore (138d), a first load bore (138e), and a first laser opening (138g), the first laser opening in communication with the first load bore, each of the first pass-through bore and the first load bore in selective communication with the output passage,
• a first delivery passage (130a) in selective communication with the first load bore,
• a first hopper tube (140) in communication with the first delivery passage, and
• a first laser ignition module (142) configured to project a first laser through the first laser opening;
• and
• a second module (150) coupled to the first module, the second module including
• a second slide member (158) including a second load bore (158e) and a second laser opening (158g), the second laser opening in communication with the second load bore, the second load bore in selective communication with the output passage,
• a second delivery passage (150a) in selective communication with the second load bore,
• a second hopper tube (160) in communication with the second delivery passage, and
• a second laser ignition module (162) configured to project a second laser through the second laser opening.
