Abstract

An activation unit (1, 10) for munitions-free decoys, active masses or active bodies (3) is characterized by an ejector tube (2) and a high-powered heater element (4) arranged around the ejector tube (2, 12), wherein the heater element is made up of at least one heating wire (6), provided with electrical current by a regulator unit. Each heating wire (6) is enclosed in a sleeve (7) and embedded in at least one heat-loss minimizing material. The active body (3) passing through the activation unit (1,10) directly or indirectly contacts with the individual elements (4) of the activation unit (1, 10). Thermal energy is transmitted to the active body (3) from the heating wires (6), which ignites at the touching or contact point.
