PROJECTILE FOR SHAPED CHARGES Filed Nov. 16, 1949 FIG.3
osroug'roa FOLLOII TI'IRU PROJECTI LE EXPLOSIVE COMPOSITION -mem HOLDER EXPLOSIVE COMPOSITION INVENTOR: SIDNEY A. MOSES ATT'Y United States Patent PROJECTILE FOR SHAPED CHARGES Sidney A. Moses, Braddock Heights, Md., assignor to the United States of America as represented by the Secretary of the Navy Application November 16, 1949, Serial No. 127,675 12 Claims. (Cl. 102-''56) (Granted under Title 35, U. S. Code (1952), sec. 266) This invention relates in general to a projectile for shaped charges and is more particularly described as a follow-through projectile of this class in which a cavity liner of the conical type has an inert core disposed at the apex of the liner.
The present method of obtaining efficiency from a shaped charge is to have the length of the explosive charge behind the cavity liner equal to two or three times the diameter of the cavity liner. Using this method, any follow-through projectile must be placed behind the point of detonation. No successful projectile of this type has yet been presented, because of the difficulty of causing the projectile to travel through the detonation products and enter the hole in the target where the jet has penetrated.
By introducing the projectile inside an inert core at the apex of the cavity liner, the follow-through projectile does not travel through the detonation products and moves only a short distance to enter the jet hole.
An important object of this invention is to increase the efiiciency of shaped charges (also calledhollow or cavity charges) by introducing a follow-through projectile or corrosive agent in the jet hole formed by the charge.
A further object. of the invention isto increase the area of damage in a target by introducing an explosive projection or corrosive agent through aajet hole made by the projectile charge, into the interior of the target.
A still further object of the invention is to incorporate the follow-through projectile in the inert core, close to the apex of the cavity liner so that it is not required to travel through the detonation products to enter a formed jet hole.
Other objects of the invention will appear in the specification and a will be apparent from the accompanying drawings, in which:
Fig. 1 is a sectional view representing a shaped charge having an inwardly projecting conical cavity liner with an inert block of material having a blunt end in contact with the liner apex;
Fig. 2 is a sectional View representing a portion of a shaped charge with an inert block having a blunt point in engagement with the liner apex;
Fig. 3 is a sectional view representing a portion of a shaped charge with an inert block having a sharp point in engagement with the linerapex;
Fig. 4 is a section view of a shaped charge-with an inert plug of broad and flat form to shape the detonation wave; and
Fig. 5 is a section view of a projectile having an inert core with a pointed tip to engage the liner apex and containing a follow-through projectile.
In a projectile of this type, the detonation of the explosive causes the detonation wave to pass around the inert core and to impact with the liner which sends out a narrow jet piercing the target. In the meantime, the propellant powder behind the follow-through projectile has burned, propelling the projectile through the jet hole where it will explode inside the target.
2,869,585 Patented Oct. 15, 1957 7 Referring now more particularly to the drawings, shaped charge containers 10 (or portions thereof are represented in Figs. 1, 2 and 3, each having a conical liner 12 with the cone thereof inserted at one end, and having 'a tetryl charge 14 at the other end, as shown in Fig. 1. Inert blocks 16, 18 and 20, less in diameter than the containers are inserted against the liner cones, leaving space around the blocks and against the liner for an explosive 22, such as pentolite.
To change the shape of the detonation wave, the inert blocks may have different contact portions for engaging the liner cones; block 16 has a plain or flat end 26; block 18 has a bluntly pointed tip 28, and block 20 has a sharp ly pointed tip 34 in contact with the liner cone tip. These different shapes may modify the shapes of the detonation waves which engage the liner substantially as shown: lines or" force 32 in Fig. 1, being more nearly normal to the liner than lines of force 34, in Fig. 2, and the latter being at a less incline than lines of force 36 as shown in Fig. 3 By varying the diameter and shape of the blocks, the angles the lines of force make with the liner surface, can be varied at will. Experiments show that where the lines of force meet the liner at a greater angle, up to a right angle, the penetration charge is increased.
'In order to reduce the explosive weight of one type of charge by the use of shaped inert cores, an outer shell 40 may be modified in shape from an outline A to include a flat inert block 42 which fits loosely in the shell and is in contact wit-b the apex of an inwardly extending core 44. At the base end, the container is slightly reduced in diameter and provided with an end cap 46 having a cen tral threaded hole 48 to receive a correspondingly threaded end. of a detonator block 50. In the block 50, is a detonator well surrounded by an explosive 52, such as pentolite, and in the container 40 surrounding the block 42 and the cone 44, is an explosive 54. In this form, the explosive weight has been reduced from 30 pounds to approximately 20 pounds with only a slight change of the metal shell. 7
inert block or plug. rnay also be used as a holder for a follow-through projectile as shown in Fig. 5. In this form, an outer shell 60 has an electric contact fuse 62 at its nose connected by a conductor tube 64 with a detonator 66 at the other end. In the nose is a liner cone 68, and engaging the tip of the cone is a bluntly pointed end 70 in the form of a cap for a recessed inert holder 72. In the recess of the holder is a follow-through projectile '74 having an explosive composition 76 which may be fired through a delay pellet 78 and a'hole 80 in the end of the holder. An explosive composition 82 fills the space in the shell 60 surrounding the holder and around the cone 68.
In all of these forms, the shaped charge may be varied by an inert plug or block, so that a follow-through charge or projectile may enter and further penetrate the jet hole formed by the charge. The detonation wave may be directed to meet the shaped charge liner more nearly normal to the conical surface of the liner, thereby increasing the penetrating power of the charge.
While various structures are described in some detail,
they should be regarded as illustrations, or examples, and
and a detonator at the other end, an inert core block abutting the apex of the liner, and an explosive surrounding the core block and the liner and extending longitudinally therefrom.
