Abstract
An assembly process is described for producing an ordnance projectile wherein the projectile maintains a compressive force on an explosive body carried therein throughout an anticipated operational temperature range. The process includes raising the temperature of the hollow projectile body to an elevated temperature, cooling the explosive body to a temperature below a lowest anticipated operating temperature of the projectile, nesting the cooled explosive body within the hollow projectile body while the projectile is at the elevated temperature, securing the explosive body and the hollow projectile body together, and normalizing the temperature of the nested bodies by allowing them to come to a common temperature, typically room temperature. Different thermal expansion characteristics of the inner and outer bodies will result in the projectile maintaining a compressive force on the explosive body at normal temperatures.
