Abstract
A propelling device for a projectile that is lying in a standby position within a rocket motor in a missile. The projectile is translated with respect to the rocket motor by means of a pyrotechnic charge before the rocket motor is ignited. The projectile is lying within a translation tube centrally located in the rocket motor. The projectile comprises a power piston in the rear end thereof. The power piston encloses a pyrotechnic power charge and a pyrotechnic squib. The translation tube is sealable closed behind the power piston and forms a closed expansion chamber for the pyrotechnic charges which, by ignition, generate gas pressure that activates the power piston and thus propels the projectile forward within the translation tube.
