Abstract:

A projectile is provided that includes a body having a front tip portion and a rear end portion. A combustion chamber base plate is operatively arranged with the rear end portion of the body and defines a combustion chamber. At least one radial discharge aperture is partially defined by the combustion chamber base plate and is arranged in fluid communication with the combustion chamber. A gas generated by igniting a combustible material is discharged through the at least one radial discharge aperture. The discharged gas impinges against a wall of a cavity formed by the moving projectile to form a reactive force that stabilizes the projectile thereby reducing the occurrence of tail-slap.
