Sub-calibred projectiles with multiple supports
The technical scope of the invention is that of sub-calibred projectiles comprising a calibred sabot formed of at least two segments and surrounding a sub-calibred penetrator. This projectile is characterized in that the sabot incorporates at least three substantially calibred support seats, axially spaced from one another. The distance between said two supports the furthest apart is greater than or equal to 3 calibers. At least one support seat, called median support seat, is formed by a push plate (PP) incorporating at least one groove to receive a band, said push plate axially located between said two other support seats.
1 . A sub-calibre projectile comprising a clibred sabot formed of at least two segments and surrounding a sub-calibred penetrator to be fired in a barrel, characterized in that said sabot incorporates at least three substantially calibred support seats, then a forward, median and rear support seats, axially spaced from one another.
2 . A projectile according to claim 1 , characterized in that the distance between said two supports the furthest apart is greater than or equal to 3 calibers.
3 . A projectile according to claim 1 , characterized in that at least one support seat, called median support seat, is formed by a push plate (PP) incorporating at least one groove to receive a band, said push plate axially located between said two other support seats.
4 . A projectile according to claim 3 , characterized in that said push plate (PP) is positioned at a distance from a median transverse plane (PM), said plane being orthogonal to said penetrator and passing through the center of gravity of said projectile, said distance being between 0.5 and 1.5 calibers.
5 . A projectile according to claim 4 , characterized in that said forward support seat is constituted by radial arms evenly spaced angularly around said sabot.
6 . A projectile according to claim 5 , characterized in that each said arm carries a foot of a plastic material at its end ensuring the guidance of said sabot in said barrel.
7 . A projectile according to claim 1 , characterized in that said rear support seat is constituted by radial studs, evenly spaced angularly around said sabot.
8 . A projectile according to claim 7 , characterized in that each said radial stud is integral with a segment of said sabot.
9 . A projectile according to claim 7 , characterized in that each said radial stud formed by the juxtaposition of two parts, each integral with a separate segment of said sabot.
10 . A projectile according to claim 9 , characterized in that each said radial stud carries a foot of a friction resistant material, for example steel, ensuring the guidance of said sabot in said barrel.
