Controlled explosive, hypervelocity self-contained round for a large caliber gun
First Claim
1. A round for selective removable placement in and firing from a large caliber gun comprising:
- a cartridge case defining a cylindrical chamber having axially opposed open and closed ends;
a plurality of annular explosive charges disposed in said chamber in axial succession from a first charge spaced from said closed end to a last charge proximate said open end, said annular charges defining a bore coaxial with said chamber and each said annular charge being shaped to generate on detonation a predetermined shock wave;
a projectile having leading and trailing ends and being disposed in chamber proximate said closed end, the trailing end of said projectile being shaped to convert to projectile acceleration the shock waves generated on successive detonation of said annular charges;
means in said chamber for selectively initially propelling said projectile axially through said bore toward said open end; and
means responsive to axial movement of said projectile in said bore for electrically detonating each said annular charge in axial succession from said first to said last.

Abstract
A round for placement and firing in the barrel of a large caliber gun, the round comprising a cartridge case defining a cylindrical chamber having axially opposed open and closed ends, a plurality of axially-adjacent annualr explosive charges coaxially-disposed in the chamber, the charges defining a bore coaxial with said chamber and each charge being shaped to generate on detonation a predetermined shock wave in the case, a projectile disposed in the chamber proximate the closed end, the projectile having a trailing end shaped to convert shock waves generated by detonation of the annular charges to projectile acceleration, an explosive in the case for initially propelling the projectile axially through the bore toward the open, end, an electrical detonator for each annular charge responsive to an electrical signal, and a power source and circuit for generating the electrical signal in response to axial movement of the projectile in the bore.

9. A round for placement and firing in the barrel of a large caliber gun, said round comprising:
-
a cartridge case defining a cylindrical chamber having axially opposed open and closed ends; a plurality of axially-adjacent annular explosive charges coaxially-disposed in said chamber, said charges defining a bore coaxial with said chamber and each said charge being shaped to generate on detonation a predetermined shock wave in said case; a projectile disposed in said chamber proximate said closed end, said projectile having a trailing end shaped to convert shock waves generated by detonation of said annular charges to projectile acceleration; means in said case for initially propelling said projectile axially through said bore toward said open end; means for separately electrically detonating each said annular charge in response to an electrical signal; and means associated with each said annular charge for generating said electrical signal in response to axial movement of said projectile in said bore. - View Dependent Claims (10, 11)

12. A round for placement and firing in the barrel of a large caliber gun, said round comprising:
-
a cartridge case defining a cylindrical chamber having axially opposed open and closed ends; an inner cylindrical shell coaxially disposed in said casing, said shell defining an inner bore and including means for defining a plurality of axially-adjacent, annular cavities between said shell and said case; an annular explosive charge disposed in each of a plurality of said annular cavities, each said charge being shaped to generate on detonation a predetermined shock wave in said case; a projectile disposed in said bore, said projectile having a trailing end shaped to convert shock waves generated by detonation of said annular charges to projectile acceleration; means for initially propelling said projectile axially through said bore toward said open end; an electrical detonator in each said annular charge; and a piezoelectric igniter electrically connected to each said detonator and disposed for compressive activation by said projectile during axial passage thereof through said bore.
