Abstract
A control system compensates for temperature dependent propellant burning characteristics by adjusting the chamber volume available to the propellant in an ammunition round. The control system includes a control tube housing, a piston assembly slidably mounted relative to the housing for movement through a drive stroke and being drivingly coupled to a trailing end of the projectile, and components responsive to the temperature of the round for adjusting the length of the drive stroke of the piston assembly in proportion to the temperature and thereby adjusting the position of the projectile and volume of the chamber in proportion to the temperature of the round.
