Abstract
A munition includes a projectile and a propellant unit. The propellant unit includes a shell having a cylindrical configuration centered on a longitudinal central axis of the munition. The shell has a cylinder opening that receives a cylinder. The cylinder is selectively rotatable in the cylinder opening about a cylinder axis, offset from the munition axis, between a plurality of firing positions. The cylinder has a plurality of propellant chambers each with a respective propellant charge. The propellant chambers are located in the cylinder so that when the cylinder is in a firing position one of the propellant chambers is on munition axis.
Claims9
A munition receivable in a chamber of a projectile launcher, the munition comprising:
- a projectile;
- and
- a propellant unit that is actuatable to produce gas under pressure, the projectile being releasably connected with the propellant unit and receiving force of the gas under pressure to cause the projectile to release from the propellant unit and travel from the launcher toward a target, the propellant unit comprising:
- a shell having a cylindrical configuration centered on a longitudinal central axis of the munition;
- the shell having a cylinder opening, the cylinder opening having an cylinder axis that is not coincident with the longitudinal central axis of the munition;
- and
- a cylinder received in the cylinder opening of the shell and being selectively rotatable in the cylinder opening about the cylinder axis between a plurality of firing positions;
- the cylinder having a plurality of propellant chambers each receiving a respective propellant charge, the propellant chambers being located in the cylinder so that when the cylinder is in a firing position one of the propellant chambers is centered on the longitudinal central axis of the munition.

- an index assembly acting between the cylinder and the shell for holding the cylinder in a selected firing position;
- and
- the cylinder having a plurality of propellant chambers, each propellant chamber for receiving a respective propellant charge, the propellant chambers being located in the cylinder so that when the cylinder is in a firing position one of the propellant chambers is centered on the longitudinal central axis, the propellant chambers being disposed in a circular array centered on the cylinder axis.
