Abstract
A variable stroke projectile postioning system compensates for temperature by adjusting the volume of a munition chamber which communicates with a projectile and contains a propellant having temperature dependent performance characteristics. The projectile positioning system includes method and apparatus which perform the operative steps of moving the projectile at a forward end of the chamber where its position defines the volume of the chamber, measuring the temperature of the propellant charge to be placed in the chamber for firing the projectile and having temperature dependent performance characteristics, and controlling the moving the projectile in response to the measured temperature of the propellant charge to cause the projectile to be placed at the exact position where it adjusts the amount of chamber volume to provide the correct degree of compensation for the measured temperature.
