Abstract
A translation and locking mechanism for a projectile that is lying in a standby position within a rocket motor in a missile, wherein the projectile is translated with respect to the rocket motor by means of a pyrotechnic charge before the rocket motor is ignited. The rear end of the projectile includes at least one radially spring biased lock and the front part of the rocket motor includes an internal circumferential groove that the at least one lock snaps into when the at least one lock is translated to the groove.

A translation and locking mechanism for a projectile that is lying in a standby position within a rocket motor in a missile, where the projectile is translated with respect to the rocket motor by means of a pyrotechnic charge before the rocket motor is initiated, wherein the rear end of the projectile and the front end of the rocket motor comprise respectively either at least one radially spring biased lock or a circumferential groove that the at least one lock snaps into when the at least one lock and the groove are aligned.
A missile comprising:
- a rocket motor defining a translation tube;
- a projectile positioned within the translation tube;
- and
- a power piston positioned within the translation tube, wherein the power piston, when activated, urges the projectile along and out of the translation tube and wherein the power piston includes a spring biased locking mechanism that engages with the front of the rocket motor when the projectile has been urged out of the translation tube to thereby retain the power piston in the rocket motor.
