ABSTRACT:
For generation of smoke screens for civilian and military applications, briquetted, combustible masses are used, which, by means of scattering charges, are spread in a buckshot-like manner. Smoke charges serve mostly toxic substances which, at least when failing to burn or when only partly burning, constitute an environmental hazard.
According to the invention, there is provided a device consisting of nontoxic, hygroscopic smoke charges fully encapsulated in a moisture-impervious ignition layer. An ammunition body comprises smoke charges of differing sizes and geometries, and facilitates the ground-covering laying of smoke screens over large target areas.
A preferred manufacturing method for the smoke charges and the ignition layer is described.
