DUAL INITIATION SUBMISSILE BACKGROUND OF THE INVENTION This invention relates to a dual initiation minibomb or submissile and, more particularly, the invention is concerned withproviding a cylindrical submissile for use in a warhead wherein simultaneous dual end initiation of the explosive produces waves which collide in the center to produce unusually high pressure and project centrally wrapped fragments in a radial pattern.
In the submissile type of warhead, there is contained a cluster of small individual bombs packaged in the warhead section. This system replaces the single massive warhead for certain operational conditions. The small bombs or submissiles are forcibly dispersed from the missile or warhead. In some designs this is accomplished by either a mechanical or chemical system. In others, the submissiles are ejected due to the opening of the outer skin causing the missile to decelerate, spilling the bombs into the air. A specific pattern is then made by the falling submissiles. These submissiles are armed during flight and either detonate on target impact or after an appropriate time delay. Submissile warhead systems can be used either for surface to air,'air to air, or air to ground applications.
The submissiles or bomblets are generally spherical or cylindrical in shape and contain a fuze, explosive, and fragments. Upon detonation of the explosive by the fuze, fragments are launched at lethal velocities. With a large number of submissiles being dispersed into a uniform pattern, probability of a kill against an area target can be greatly enhanced over that attainable with a single massive warhead. This can be especially true as missile guidance errors become larger.
SUMMARY OF THE INVENTION The present invention provides a minibomb for use in a submissile system for explosively projecting fragments in a radial pattern at lethal velocities from a small volume mechanism. Higher fragment velocities are realized from the hereinafter described minibomb than from submissiles of equivalent size due to the centralized detonation wave convergence. Simultaneous dual end initiation produces an enhanced blast effect when the detonation wave converges in the central area of the minibomb. Aerodynamic control of the minibomb can be easily maintained using the simple flute arrangement without moving parts.
Accordingly, it is an object of the invention to provide a minibomb or submissile wherein fragments therefrom are explosively projected in a radial pattern at lethal velocities from a small volume mechanism.
Another object of the invention is to provide a submissile having enhanced blast pressures within a decreased volume so that a greater number of submissiles can be loaded in a warhead section while maintaining lethal performance characteristics.
Still another object of the invention is to provide a minibomb wherein the fragments are wrapped around the center periphery of a cylindrical explosive charge which is detonated simultaneously at each end by the operation of a pair of main charge boosters.
A further object of the invention is to provide a cylindrical minibomb having dual end initiation which is accomplished by simultaneously initiating one end of each of two equal lengths of an explosive wave carrier and transferring the detonation to a booster at each end of the main charge.
A still further object of the invention is to provide a cylindrical minibomb which is simultaneously detonated at each end of the main explosive charge causing detonation waves which collide and produce extremely high pressures at the center of the minibomb in the fragmentation area.
Another still further object of the invention is to provide a minibomb wherein an enhanced blast efi'ect and fragmentation pattern is achieved through centralized detonation wave convergence. The high pressures thus obtained serve to project the fragments at a higher velocity than can be attained with typical single end or center explosive charge initiation.
These and other objects, features, and advantages of the invention will become more apparent after considering the description that follows taken in conjunction with the attached drawing of a preferred embodiment of the invention.
DESCRIPTION OF THE DRAWING The drawing is a view in perspective of a minibomb or submissile according to the invention partially cut away to show the structural arrangement of the internal elements.
DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawing, there is shown a minibomb or submissile generally designated by the reference numeral 13 having a plastic housing 15 which provides a case to contain the internal elements and the aerodynamic surfaces in the form of fins or flutes 17 which serve to control flight orientation of the minibomb. One end of the submissile 13 includes a fuze 19 which is armed after the submissile is dispersed into the air. A fuze booster 21 which is initiated by the fuze 19 is located in contact therewith. Attached to the fuze booster 21 are two equal lengths of an explosive wave carrier 23 such as mild detonating fuze (MDF) or sheet explosive. The other ends of the explosive wave carriers 23 are attached to two main charge boosters 25, one each located at opposite ends of the main explosive charge 27. The main charge boosters 25 are initiated simultaneously causing the detonation waves to proceed from the ends toward the center of the main charge 27 of the minibomb 13. At the outer periphery of the center portion of the minibomb 13, there are positioned a number of discrete fragments 29 which are reacted upon by the detonation waves which collide and produce a high pressure region. The fragments 29 are thus projected radially at a lethal velocity away from the submissile.
The minibomb 13, in a typical embodiment, may be comprised of a cylindrical submissile approximately 1.25 inches in diameter, 2.2 inches long, and weighs grams. It projects a single ring of 25-grain fragments 29 radially at velocities of approximately 3,700 feet per second by application of simultaneous dual end initiation of the explosive 27. Equal lengths of mild detonating fuze 23 provide a detonating path from a single fuze 21 to the main charge boosters 25. The plastic housing 15 provides a case and aerodynamic surfaces 17 to control flight orientation.
MODE OF OPERATION In operation, the minibomb 13 is part of a cluster of small individual bombs packaged in the warhead section of a submissile type of warhead (not shown). These small bombs are forcibly dispersed from the warhead. After being dispersed into the air, the fuze 19 is armed. The fins 17 control submissile orientation thus providing desired impact angle. Upon impact with the target or the ground, the fuze l9 initiates the fuze booster 21 which initiates both lengths of mild detonating fuze 23. The detonation wave is carried to the main charge boosters 25 which initiate each end of the main charge 27 simultaneously. As the detonation progresses toward the center of the main charge 27, the waves from each end collide producing a high pressure region. The fragments 29 are then reacted upon by the gas pressure and are projected away from the submissile l3 radially.
Since the hereinbefore described minibomb 13 is smaller in size than conventionally initiated munitions with similar performance requirements, more submissiles can be packaged in the volume allotted. An enhanced blast effect operating to produce higher fragment velocities is achieved as a result of the centralized detonation wave convergence. The simultaneous dual end initiation arrangement is simple and uncomplicated and aerodynamic control of the submissile can be easily maintained using the simple flute arrangement shown without moving parts.
Although the invention has been illustrated in the accompanying drawing and described in the foregoing specification in terms of a preferred embodiment thereof, the invention is .not limited to this embodiment or to the particular configuration mentioned. It will be apparent to those skilled in the art that the composition of the explosive 27 can be varied with a corresponding variation of the fragment velocity depending on the properties of the composition. Also, the geometry of the explosive charge can be changed as to length and diameter to meet specific demands. The basic configuration found to be most efficient has a length to diameter ratio of approximately 1.75. The fragments 29 should remain centralized on the main charge 27. but additional fragments can be added along cylinder to increase the lethality of the submissile.
It should be understood that various changes, alterations, modifications and substitutions. particularly with respect to the construction details can be made in the arrangement of the several elements without departing from the true spirit and scope of the appended claims.
Having thus described our invention, what we claim and desire to secure by Letters Patent of the United States is:
