Abstract: A pyrotechnic charge structure, in particular for use as propellant in a rocket motor, is disclosed. The charge structure has a predetermined longitudinal extension and cross sectional area adapted to the intended purpose. The pyrotechnic charge structure (1; 2; 3; 4) is in cross sectional view in cellular form aimed at having similar wall thickness for all the cells of the charge structure. The wall (6) of the cells comprises the pyrotechnic charge, i.e. the propellant, and each cavity of the cells occupies air or oxygen-rich gas.

Abstract: A training rocket for smoke development. The training rocket includes a rocket tube which contains powder and constitutes a propulsion motor for the rocket. The rocket includes a forward training head which contains a smoke composition adapted to emit visible smoke upon impact. An igniter charge, such as a tracer charge, which can be ignited by the propellant powder is situated in the rearmost of the training head, behind a bursting charge which can be ignited by the igniter charge. The igniter charge and the bursting charge are situated behind the smoke composition in the training head, for igniting the smoke composition, in a capsule which can be forced rearwardly from the training head due to the increased pressure caused by combustion of the smoke composition, whereby an aperture is formed for passage of smoke gases rearwardly in the rocket, through the rocket tube and out of it.
