Munition with Unexploded Ordnance Limiting

摘要

A munition includes a projectile and a propellant unit. A propellant insert in the propellant unit has at least two propellant chambers each receiving a respective propellant charge. A primer mechanism is actuatable to ignite all of the propellant charges in the propellant insert. The combustion products of a selected one of the propellant charges are directed to the projectile and the combustion products of the non-selected propellant charges are vented.
