Abstract

Un elemento retardador de tiempo rígido formado por un tubo metálico con un interior de tubo reducido en un primer extremo, un primer segmento de una composicion pirotécnica dentro del interior del tubo, lindando con la composicion ignífera y un segundo elemento de la composicion pirotécnica dentro del interior del tubo lindando con el primer segmento en una superficie de interfaz donde la composicion pirotécnica adyacente a una porcion de la superficie de interfaz se comprime en un grado inferior al resto de la composicion pirotécnica.A rigid time retardant element formed by a metal tube with a reduced tube interior at a first end, a first segment of a pyrotechnic composition within the interior of the tube, bordering the flame retardant composition and a second element of the pyrotechnic composition within the inside the tube bordering the first segment on an interface surface where the pyrotechnic composition adjacent to a portion of the interface surface is compressed to a lesser extent than the rest of the pyrotechnic composition.
