Abstract
Official abstract text for this publication.
Methods and devices for ejecting a grain assembly from a casing of a flare. Where a combustible material in the casing is ignited to eject the grain assembly and one or more of the following features are provided to the device: imparting a spin on the grain assembly after it is ejected from the casing, stabilizing a flight of the grain assembly or generating a thrust from an aft end of the grain assembly.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for ejecting a grain assembly from a casing of a flare, the method comprising: igniting a combustible material in the casing to eject the grain assembly; generating a thrust from an aft end of the grain assembly, wherein the generating of the thrust from an aft end of the grain assembly comprises providing one or more nozzles on the aft end of the grain assembly; and restraining the one or more nozzles in a first shape inside the casing and removing the restraint to allow the one or more nozzles to take a second shape, the second shape being more efficient as a nozzle than the first shape.
