Abstract
A gun-fired spin-stabilized projectile of good aerodynamic shape (i.e. with a long forward tapering section) is centered in the gun barrel at its forward end by means of a series of circumferentially spaced apart permanently fixed radially extending projections, and at its rearward end, by means of either the maximum diameter of the projectile body or by means of a driving band mounted on a rear portion of the body. In the latter case, the maximum diameter of the projectile body is slightly less than the diameter lands of the gun and the driving band is constructed in such a manner as to be separated from the body after firing by centrifugal force and air drag.
Claims10
A gun-fired spin-stabilized projectile having a longitudinally extending body, a driving band mounted on a rear portion of the body and being engageable with rifling in a gun barrel during firing to cause spin to be imparted to the projectile, said body tapering smoothly from a maximum diameter forwardly of the driving band to the forward end of the body, said tapering portion carrying a series of circumferentially spaced apart, permanently fixed, radially-extending projections, each projection having an outer surface parallel to the longitudinal axes of the body and engageable with the wall of the gun barrel to center the forward portion of the projectile therein, and also being shaped to minimize air drag during flight of the projectile after firing, and the major part of the radial extent of the projections lying within the maximum diameter of the body.
