Embodiment Construction

[0026] Turning first to FIG. 1 there is shown a tank 12 in accordance with the present invention having filler packets 14 positioned within the interior thereof. These packets are preferably thermally conductive and positioned in thermal contact with the exterior walls 16 of the tank to thereby dissipate heat from the tank wall, as is now well known in the art. In the preferred embodiment, the individual filler packets 14 of the present invention (one embodiment of which is shown in FIG. 2) each exhibit a thermally conductive porous fuel permeable body portion 18 for accommodating fuel within the tank and suppressing explosion by thermal conduction. However, for suppressing ballistic shock, a denser portion or member 20 is provided within each packet 14, which denser portion or member 20 has a greater mass density than that of the sheet of foil material in its unexpanded state used for the outer body portion 18, as more fully described below.

Abstract

An improved tank design incorporates a new shock dispersing filler packet insert. This filler packet is formed from a sheet of foil and exhibits in its unformed shape an expanded foil center and an unexpanded denser border. All of the edges of the foil sheet are then folded inwardly and the filler insert is finally rolled and secured to produce a cylindrical packet having a dense core. Once the fuel tank is filled with these packets, the ballistic shock is dissipated by the distributed dense portions within the tank.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This is a Continuation-in-Part of prior U.S. patent application Ser. No. 10 / 367,467, now abandoned.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The present invention relates generally to receptacles, such as fuel tanks, used to hold combustible liquid, and further relates to explosion suppression devices for such tanks in the nature of filler elements or filler packets positioned within the tank. More particularly, this invention relates to a new design for such a filler packet which improves its effectiveness in maintaining tank integrity during the impact and subsequent penetration by a ballistic body. [0005] 2. Description of the Prior Art [0006] It is well known in the prior art that a filler mass insert or packet may be formed from expanded foil mesh and used as an insert within a tank to suppress explosion. This “expanded” ...
