Abstract:
1. A flare deployable from a launcher, the flare comprising: a flare grain configured to produce an electromagnetic radiation emission during combustion; a housing having a first portion and a second portion, the first portion having an inlet for receiving combustion products, the second portion having an outlet, the outlet being positioned to propagate combustion between the second portion of the housing and the flare grain; a combustible carrier material movable from the first portion of the housing to the second portion of the housing, the combustible carrier material being ignitable in the first portion of the housing and capable of sustaining combustion while being moved to the second portion of the housing; a seal positioned to block a migration of combustion products between the first and second portions of the housing when the combustible carrier material is in the first portion of the housing; a biasing mechanism urging the combustible carrier material toward the second portion of the housing; and a device movable between a first position and a second position, the device in the first position restricting the biasing mechanism from moving the combustible carrier material to the second portion of the housing and the device in the second position allowing the biasing mechanism to move the combustible carrier material to the second portion of the housing, and a package containing the flare grain, the package includes a first portion of tape surrounding the flare grain, the first portion of tape including the aperture to communicate with the outlet of the housing, and wherein the system further comprises a second portion of tape surrounding a portion of the housing, a portion of the seal, and a portion of the package, the second portion of tape being positioned to prevent the migration of combustion products through the aperture except from the outlet.
