Abstract
This invention relates to a combination of a gun having a rifled barrel and a round of enhanced performance ammunition, and to a projectile for use in the combination. The invention is especially, but not exclusively related to a projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising: an elongate metal core, a ceramic tip with a Vickers Hardness greater than said metal core, said ceramic tip abutted with one end of the elongate metal core, wherein a deformable jacket or deposited coating, surrounds the elongate metal core and ceramic tip, such that said jacket or coating defines the nominal calibre of said projectile.
Claims20
A projectile with a nominal calibre, for use in a rifled barrel, the proj ectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip abutted with one end of the elongate metal core;
- and
- a deformable jacket or coating that surrounds the elongate metal core and the ceramic tip, such that said deformable jacket or coating defines the nominal calibre of said projectile;
- wherein said deformable jacket or coating defines an inner cavity in the proj ectile, and the ceramic tip is in a range of from 5 to 25% of a fill volume of the inner cavity.
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip having a first end which engages with the elongate metal core and a second end which has a taper with respect to the first end;
- and
- a deformable metal jacket that surrounds the elongate metal core and the ceramic tip, such that said deformable jacket defines the nominal calibre of said projectile, wherein said deformable metal jacket defines an inner cavity in the projectile, and the ceramic tip is in a range of from 5 to 25% of a fill volume of the inner cavity, wherein during firing of the projectile lands of rifling in the rifled barrel deform the deformable metal jacket so as to impart spin on the projectile, and wherein during firing of the projectile the deformable metal jacket is deformed into the grooves of the rifling in the barrel.
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip having a first end which engages with the elongate metal core and a second end which has a taper with respect to the first end;
- and
- a deformable metal coating that surrounds the elongate metal core and the ceramic tip, such that said deformable metal coating defines the nominal calibre of said projectile, wherein said deformable metal coating defines an inner cavity in the projectile, and the ceramic tip is in a range of from 5 to 25% of a fill volume of the inner cavity, wherein during firing of the projectile lands of rifling in the rifled barrel deform the deformable metal coating so as to impart spin on the projectile, and wherein during firing of the projectile the deformable metal coating is deformed into the grooves of the rifling in the barrel.
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip abutted with one end of the elongate metal core;
- and
- a deformable jacket or coating that surrounds the elongate metal core and the ceramic tip, such that said deformable jacket or coating defines the nominal calibre of said proj ectile;
- wherein the ceramic tip has a physical or chemical bond to the elongate metal core, the physical or chemical bond comprising fusion, adhesive, plasma deposition, and/or additive layer manufacture.
