Benefits of technology

The present invention is about improving solid explosive munitions by using better casing materials and linings, as well as adding reflective material on the inner wall of the casing to enhance performance. The invention also aims to reduce the amount of explosive needed and provide a directional blast to optimize effects and reduce collateral damage. Additionally, the invention produces munitions with increased equivalent mass ratios. The reflective material on the inner surface of the casing redirects electromagnetic radiation generated by the detonation process back into the interior of the munition, enhancing the detonation processes and resulting in enhanced air blast impulse.

Problems solved by technology

However, as the basis for these differences in performance enhancement had not been fully understood, it was difficult or impossible to utilize these observed enhancements in the design of explosive munitions.

Embodiment Construction

[0030] In describing a preferred embodiment of the invention illustrated in the drawings, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0031] As previously discussed, the data in FIG. 1 illustrates the relative performance improvement in terms of the equivalent mass ratios of various casing materials, as a function of the ratio of the casing mass to the charge mass. While this data indicates the desirability of using particular casing materials, as opposed to other alternative materials, the basis for the differences in performance have not been fully characterized.

[0032] In development of the present invention, the data of FIG. 1 was segregated according to specific casing material, as shown in FIG. 2A (steel), FIG. 2B (lead...

Abstract

A solid explosive munition casing for an explosive charge, the inner surface of the casing including a material that is highly reflective in the optical and infrared spectrum. Through this reflectivity, electromagnetic radiation generated by the detonation process is redirected back into the interior of the munition to increase its explosive output.

Description

[0001] This is a divisional application of co-pending application U.S. Ser. No. 10 / 606,827 filed Jun. 27, 2003, which claims priority from U.S. Provisional application Ser. No. 60 / 394,662 filed Jul. 10, 2002.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention is related to the field of munitions and, more particularly, to improved munitions design reflective casing constructions for solid explosive munitions demonstrating improved performance characteristics. [0004] 2. Description of the Related Art [0005] Historically, the radiation that accompanies chemical reactions, such as the detonation of high energy explosive munitions, has been treated as an incidental, minor release of energy. Furthermore, explosive munitions have traditionally been made using highly absorbing, low reflecting materials such as tar, asphalt-like substances or black polymers to line the casings and cushion the munition. [0006] It is known that high energy devices that va...
