Abstract
A system and method for improving the process of mechanical translation of projectiles by a spring mechanism that is built of a smart material and that is activated by an electric pulse, to provide a controlled translation of a projectile before firing or, in case of pre-firing termination, in order to restore the projectile to its original position after translation. The pre-firing translation using the spring mechanism provides a more controlled process and reduces the risk associated with the conventional propulsion charge translation design. The ability to return the projectile to its initial state after translation affords a significant advantage over the conventional propulsion charge design since it enables the projectile firing to be terminated even after translation, unlike in the conventional design whereby the projectile firing is irreversible upon a mechanical translation by setting off the propulsion charge.
