Active body with an active mass and a covering

摘要

Active body comprising an active mass (1) for the pyrotechnic generation of a mist or for providing a pyrotechnic mock target and a sheath (2) for enclosing the active mass (1) and optionally a firing set, wherein between the active mass (1) and the sheath (2) at least one gap (3) is present, the gap (3) being such that it extends over at least 75% of an entire surface of the active mass (1) and a flame extends through the entire gap (3) between the active mass (1) and the envelope (2) can spread, the envelope (2) being such that it only after the flame has spread through the entire gap (3) under one in the envelope (2) by a reaction the effective mass (1) and - if available - the firing set building up pressure.
