  • Publication number: 20240174581
    Abstract: 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.
