Abstract
A baseplug for a target-penetrating projectile containing an explosive in which the baseplug is fabricated in two components each preferably fabricated from a powdered pyrophoric material. The powdered pyrophoric material may be zirconium or titanium or alloys thereof which is charged with hydrogen which upon burning of the baseplug is released to increase the fine start capability of the projectile.
Claims20
A baseplug for a target-penetrating projectile containing an explosive charge, said baseplug comprising:
- at least a first and second member;
- said first member being substantially frustoconical and having a bore extending from its forward end at least a portion of the way therethrough;
- said second member being cup-shaped and having an aft end and a forward extending wall portion, said wall portion having an internal surface tapering forwardly and outwardly;
- said first member having its aft end received within the opening defined by the wall portion of said second member, said internal surface of said second member being in the mating engagement with the external surface of the aft end of said first member;
- and
- said first and second member comprising from about 5 to about 30% volume hydrogen.
An explosive-containing assembly for insertion within an outer jacket of a target-penetrating projectile, the assembly comprising;
- an elongated generally cylindrical metallic sheath being open at its opposite forward and aft ends;
- and
- a cup-shaped baseplug being closed at its aft end and open at its forward end, the baseplug being inserted into the aft end of the sheath to define an explosive-containing chamber therewith and being connected in an oblique locking interfit with the sheath,
- said baseplug being formed from a powdered pyrophoric material and containing hydrogen.
A baseplug for a target-penetrating projectile containing an explosive charge, said baseplug comprising:
- at least a first and second member;
- said first member being substantially frustoconical and having a bore extending from its forward end at least a portion of the way therethrough;
- said second member being cup-shaped and having an aft end and a forward extending wall portion, said wall portion having an internal surface tapering forwardly and outwardly;
- said first member having its aft end received within the opening defined by the wall portion of said second member, said internal surface of said second member being in the mating engagement with the external surface of the aft end of said first member;
- and
- said first and second member being comprised of a material selected from the group consisting of zirconium, titanium, alloys thereof, and mixtures thereof, said first and second members further containing hydrogen.
A baseplug for a target-penetrating projectile containing an explosive, the baseplug comprising:
- a cup-shaped member being closed at its aft end and open at its forward end, said baseplug being a pyrophoric material containing hydrogen.
A target-penetrating projectile with enhanced destructive capability after penetration of the target, comprising:
- an elongated outer metallic jacket having forward and aft ends and defining a cavity extending therebetween;
- an explosive containing assembly disposed within the cavity of the jacket and spaced from the forward end of the jacket, the assembly being closed at its aft end and open at its forward end so as to define a chamber in communication with the cavity of the jacket at the forward end thereof;
- an incendiary charge contained within the cavity at the forward end of the jacket, the incendiary charge capable of igniting and generating a signal upon impact of the forward end of the jacket with the target;
- and
- an explosive charge contained within the chamber of the cup-like assembly, the explosive charge capable of exploding in response to the signal generated by the incendiary charge and of producing a build-up of explosive pressure within the assembly chamber which ultimately causes destructive fragmentation of the assembly and jacket;
- said assembly including a generally cylindrical tungsten sheath and a baseplug structure, an interior surface of an aft portion of the sheath and an exterior surface of a forward portion of said baseplug structure having complimentary tapered configurations providing a locking interfit therebetween, the baseplug being composed of a powdered pyrophoric material capable of ignition by the buildup of explosive pressure and of prolonged burn after target penetration and containing hydrogen which is releasable upon burning of the pyrophoric material.
An explosive-containing assembly for insertion within an outer jacket of a target penetrating projectile, the assembly comprising:
- an elongated generally cylindrical metal sheath being open at its opposite forward and aft ends;
- a cup-shaped baseplug being closed at its aft end and open at its forward end, the baseplug being inserted into the aft end of the sheath to define an explosive-containing chamber therewith,
- said baseplug including at least a first and a second member;
- said first member having an exterior surface which is substantially frusto conical and having a bore extending from its forward end at least a portion of the way therethrough;
- said second member being cup-shaped and having an aft end and a forward extending wall portion defining an opening in said second member, said wall portion having an internal surface tapering forwardly and outwardly;
- said first member having its aft end received within the opening defined by the wall portion of said second member, said internal surface of said second member being in mating engagement with the external surface of the aft end of said first member;
- and
- the forward end of said first member being connected to the aft end of the sheath by an oblique locking interfit with the sheath.
