The present technology is directed to igniter pellets for use with an expendable countermeasure flare assembly with an igniter assembly with a pellet receptacle. An igniter pellet of one or more embodiments has a moisture insensitive first layer formed by a first composition comprising a mixture of a fuel material that includes Boron, an oxidizer material that includes Bismuth Oxide and/or Potassium Perchlorate, and a granular matrix binder holding the fuel material and the oxidizer material together. A second layer is formed by a second composition that has a fuel material that includes Magnesium, an oxidizer that includes Polytetrafluoroethylene, and a binder material that includes a fluoropolymer elastomer. The second layer is contained in the pellet receptacle and covered by the first layer, so that the second layer is isolated and protected from ambient moisture by the moisture insensitive first layer.

The present technology is generally directed to assembling and testing ampoules, and associated systems, devices, and methods. Each ampoule can include a body portion configured to carry a marking material within an interior of the body portion, and a base portion configured to couple to the body portion to seal the interior of the body portion. The ampoules can be assembled and/or tested in an inverted orientation. In the inverted orientation, the ampoule can include a gap between the marking material and the base portion. For example, the ampoule can be positioned within a leak detection system and the ampoule's gap can be aligned with one or more leak detection components configured to analyze the gap for leak-related indicia.

METHOD FOR MAKING PYROTECHNIC MATERIAL AND RELATED TECHNOLOGY
A method for making a pyrotechnic composition in accordance with an embodiment of the present technology includes flowing metal powder, polytetrafluoroethylene powder, and binder powder in separate respective feed streams toward an extruder. The binder powder includes adhesive material and polytetrafluoroethylene anticaking material coating the adhesive material. The method further includes interspersing the metal powder, the binder powder, and the fluoropolymer powder to form a mixture. This mixture is then subjected to an extrusion process during which the anticaking material coating the adhesive material is disrupted. This releases the adhesive material to bind together the metal powder and the polytetrafluoroethylene powder in the extrudate. The powder mixture includes no solvent at any time between being formed and being extruded, yet the extrudate is well-mixed and cohesive.

A projectile (100, 100a, 100b, 100c) containing two chemiluminescent dye components (123, 125), a dye powder (126) and one or more capsules (170) containing a pyrophoric substance. Upon impact at a target, a nose cap (110) of the projectile (100, 100a, 100b, 100c) and the capsule(s) (170) become broken, thereby allowing the pyrophoric substance to oxidize and emit an infra-red signal to mark the strike point. Oxidation of the pyrophoric substance is controlled, to allow the projectile to be fire-safe.
