Abstract : This invention has to do with propellants for use in gun systems. More specifically, this invention has to do with a novel shape for propellant grains which enhances the burning characteristics of the propellant material such as to achieve higher muzzle velocity of a projectile without increasing the maximum experienced pressure within the barrel of the gun in use. As is well known, the purpose of propellant materials in a gun system is to provide a source of energy for accelerating a projectile within the bore of a gun so that a desired muzzle velocity for the projectile is achieved. The projectile, initially at rest, is accelerated by force resulting from the generation of high pressure gaseous products in response to the ignition and burning of the propellant material. As is also generally known, the burning of solid propellants ordinarily utilized in gun systems is initiated by some action, e.g., the release of a firing pin, which generates a small amount of hot gas in proximity to the propellant thus causing the propellant material to ignite and the burn process to commence.
