Method and device for mixing and initiating a pyrotechnic charge, comprising at least one coherent porous fuel structure (16) and at least one oxidizer (8). According to the invention, the coherent porous fuel structure (16) and the oxidizer (8) are placed apart in a mixing device (1, 20) to prevent unintentional ignition, and in which the oxidizer (8), in response to the action of a force upon the mixing device (1, 20), for example upon firing of an artillery shell, is transported into the coherent porous fuel structure (16), after which the obtained pyrotechnic charge is initiated after a set time delay.

1. A method for mixing and initiating a pyrotechnic charge, comprising at least one coherent porous fuel structure and at least one oxidizer, in which the said at least one coherent porous fuel structure and the said at least one oxidizer are placed apart in a mixing device, wherein the oxidizer, in response to the possible action of an acceleration force Fa, or a rotation force Fr, or an acceleration force Fa and a rotation force Fr, upon the mixing device, is transported into the coherent porous fuel structure, after which the obtained pyrotechnic charge is initiated, wherein the porous fuel structure is placed in a fuel chamber and in that the oxidizer is placed in a first oxidizer chamber and in a second oxidizer chamber, in which the oxidizer in the first oxidizer chamber, in response to the action of a rotation force Fr upon the mixing device, is transported to the fuel chamber via a first connecting duct, and/or in that the oxidizer in the second oxidizer chamber, in response to the action of an acceleration force Fa upon the mixing device, is transported to the fuel chamber via a second connecting duct, after which the pyrotechnic charge is initiated with an initiating device and wherein the first connecting duct is opened by the activation of a rotation-sensitive opening device and the second connecting duct is opened by the activation of an acceleration-sensitive opening device. 2. A method for mixing and initiating a pyrotechnic charge comprising at least one coherent porous fuel structure and at least one oxidizer, in which the said at least one coherent porous fuel structure and the said at least one oxidizer are placed apart in a mixing device, wherein the oxidizer, in response to the possible action of an acceleration force Fa, or a rotation force Fr, or an acceleration force Fa and a rotation force Fr, upon the mixing device, is transported into the coherent porous fuel structure, after which the obtained pyrotechnic charge is initiated, wherein the porous fuel structure is placed in a fuel chamber and in that the oxidizer is placed in ant oxidizer chamber, in which the oxidizer is transported to the fuel chamber via a connecting duct, in response to the action of an acceleration force Fa and/or rotation force Fr upon the mixing device, after which the pyrotechnic charge is initiated with an initiating device and wherein that the connecting duct is opened by the activation of an acceleration- and rotation-sensitive opening device.
