Abstract

A container, such as a standard aircraft unit load device, a truck trailer, a ship'"'"'s cargo compartment, or the like, is fitted with a blast mitigating material located within the container. The blast mitigating material can be fitted to the container during manufacture, or an existing container can be retrofitted.

Claims

1. A method for protecting an aircraft from the effects of a blast comprising at least partially lining unit load devices and other containers within the aircraft with a blast mitigation material;

wherein said blast mitigation material is in the form of an assembly of two flexible sheets arranged one over the other and joined by a plurality of seams, the seams being arranged so as to form cells or recesses in the space between the sheets, and wherein the cells or recesses are filled solely with perlite, wherein the perlite is free-flowing within the cells.

3. The method according to claim 1 wherein the unit load device and other containers are further at least partially lined with a frangible material.

4. The method according to claim 3 wherein the frangible material is fiberglass.

5. The method according to claim 1 wherein the unit load devices and other containers are at least partially lined with at least one additional material selected from the group consisting of thermal insulation, fragment slowing or stopping material, intumescent materials, and materials impervious to alpha, beta or gamma rays.

6. The method according to claim 1 wherein the other containers include behind panels in lavatories adjacent the fuselage.

7. The method according to claim 1 wherein the other containers include an area above the aircraft'"'"'s central fuel tank.

8. The method according to claim 1 wherein a single panel of the blast-mitigating material weights less than nine pounds.

2. The method according to clam 1 wherein the other containers are overhead bins in aircraft.
