<p>A propelling device for a projectile (1) that is lying in a standby position within a rocket motor (10) in a missile is disclosed. The projectile (1) is translated in respect of the rocket motor (10) by means of a pyrotechnic charge (2) before the rocket motor (10) is initiated. The projectile (1) is lying within a translation tube (12) centrally located in the rocket motor (10). The projectile (1) comprises a power piston (9) in the rear end thereof. The power piston (9) encloses a pyrotechnic power charge (2) and a pyrotechnic squib (3). The translation tube (12) is sealingly closed behind the power piston (9) and forms a closed expansion chamber (7) for the pyrotechnic charges, which by ignition generate gas pressure that activates the power piston (9) and thus propells the projectile (1) forward within the translation tube (12).</p> |
