Programmed-splitting solid propellant grain for improved ballistic performance of guns |
摘要 |
The invention is an improved solid propellant grain, wherein the solid propellant grain is structured to provide a programmed method and system for splitting the solid propellant grain at a programmed moment to provide an increase in the burning surface. The programmed-splitting of the solid propellant grain provides improved ballistic performance of guns, which yields a higher muzzle velocity for a given projectile without increasing the maximum pressure exerted on the gun chamber. The improvement consists of embodiments that are a plurality of slits of various configurations through the longitudinal length of each grain of solid propellant. The improvement includes a structure to delay end burning of the grains until the longitudinal exterior surface burns sufficiently to split the grain into a plurality of sections at a programmed moment when the increased burning surface is desired to occur. The improvement also consists of another embodiment wherein the grain is structured in a spiral configuration to provide a similar increased burning surface for a programmed moment when the increased burning surface is desired to occur.
