ABSTRACT:
A decoy flare is disclosed which includes illuminant disposed within a housing. A shroud is slidably attached to the housing for deployment from a retracted position to an extended position. A plug is attached to the aft end of the shroud and is configured with a radially beveled, nozzle-contacting surface. The plug is positioned and configured to sealingly engage the nozzle when the shroud is in the retracted position and to disengage the nozzle upon deployment of the shroud to the extended position. The plug is configured with a plume-contacting surface positioned at an angle to the path of the plume when the shroud is in the extended position for enhancing the cross-sectional area of the plume of the flare.
