Abstract
A pyrotechnic assembly has an outer container for a plurality of pyrotechnic elements, each of which has a propellant charge, to propel the element out of the container, and a pyrotechnic charge, for example for producing a radiation-blocking screen. The container may be used as a fixed launcher for the elements or may itself be a projectile or missile from which the elements are ejected in flight. A plurality of different pyrotechnic charges may be included in the element.
Claims9
A pyrotechnic assembly comprising an outer tubular launching tube sealed at one end with an end cover, and a plurality of pyrotechnic elements mounted in a stack formation therein, each element having a main pyrotechnic charge and having a propellant charge positioned between itself and the next element to propel the element out of the one end of the tube, wherein each element includes a pyrotechnic delay charge for igniting its propellant charge whereby the propellant charges are ignited at predetermined intervals, and wherein each element includes a further pyrotechnic delay charge to delay the ignition of the main pyrotechnic charge until a predetermined time after ignition of its propellant charge.
