Abstract
A projectile (100) for piercing armor including a cruise propellant (116) for maintaining a cruise velocity of the projectile. The projectile (100) also includes an acceleration rocket motor (109) activated after launch for accelerating the projectile (100) from the cruise velocity to a penetration velocity, in a final stage of flight of the projectile.
Claims13
A projectile device for piercing armor, the projectile device being fired from the barrel of a gun, the projectile device comprising:
- (a) a shell;
- and
- (b) a cartridge associated with said shell prior to firing, said cartridge containing a launch propellant for accelerating said shell along the barrel of the gun to a muzzle velocity,
- wherein said shell includes:
- (i) a cruise rocket motor configured for maintaining a substantially constant cruise velocity of said shell for a first period after leaving the barrel of the gun;
- and
- (ii) an acceleration rocket motor configured for accelerating said shell from said cruise velocity to a penetration velocity in a final stage of flight of the shell.

A method for propelling a shell fired from the barrel of a gun to pierce armor of a target, the method comprising:
- (a) employing launch propellant for accelerating the shell along the barrel of the gun to a muzzle velocity, said launch propellant being located within a cartridge associated with the shell prior to firing;
- (b) employing a cruise rocket motor located within the shell for maintaining a substantially constant cruise velocity of the shell for a first period after leaving the barrel of the gun;
- and
- (c) employing an acceleration rocket motor located within the the shell for accelerating the shell from said cruise velocity to a penetration velocity in a final stage of flight of the shell.
