The method of calculating the behavior of a projectile propelled by a pre-burned propellant in a chambered gun is reviewed. The influence of gas in front of the projectile in the barrel is discussed, as is the procedure to take account of gas frictional and heat-transfer effects. The method of calculation by hand of the perform-ANCE OF TWO-STAGE GUNS IS THEN OUTLINED. Some results obtained from an electronic computing machine are compared with experimental results.
