Abstract
An adjustable range munition has at least one gas vent that is selectively variable to affect the amount of force that is directed onto the projectile upon actuation of the propellant section, thereby to control the range of the munition.
Claims16
An adjustable range munition comprising:
- a propellant section that is actuatable to produce gas under pressure;
- and
- a projectile releasably connected with the propellant unit;
- the projectile having an engagement surface that receives force of the gas under pressure to cause the projectile to release from the propellant unit and travel toward a target;
- the projectile having at least one gas vent that is selectively variable to affect the amount of force that is directed onto the projectile by the gas under pressure upon actuation of the propellant section.

An adjustable range munition comprising:
- a propellant section that is actuatable to produce gas under pressure;
- and
- a projectile releasably connected with the propellant unit;
- the projectile having an engagement surface that receives force of the gas under pressure to cause the projectile to release from the propellant unit and travel toward a target;
- the munition having means for affecting the amount of force that is directed onto the projectile by the gas under pressure upon actuation of the propellant unit;
- wherein the means for affecting includes a movable member that is movable between a first position closing a vent and a second position opening the vent to selectively vary the vent;
- and
- wherein the movable member is rotatable on a body of the projectile.
