Abstract

Commercial aircraft fuel tanks, such as the center wing tank or body tanks, can be subject to explosion hazard due to heat balance around the tanks. Various embodiments of the present disclosure reduce the flammability exposure of the fuel tank by drawing cold air from a cold air unit of the aircraft and passing the air to a space proximate the fuel tank, without disrupting the cold air system in flight performance.

Abstract

Body containment constructions, materials, and methods of use for bio-cremation processes are disclosed. Preferably, the containment constructions of the present invention provide the functionality of liquid containment and also the functionality of body presentment for viewing purposes, if desired, in addition to bio-degradability. Advantageously, liquid containment is provided in a body containment construction that is sufficiently liquid impervious, allows for body transport by sufficient structural support, and is decomposable within the time period for a bio-cremation process. More preferably, the containment construction will dissolve or decompose within a normal procedural time period without leaving any component remaining from the containment construction. According to an aspect of the present invention, a body containment bag is provided that is made from a structural material that is combined with a liquid containment material and one or more closures, wherein the body containment bag is effectively usable for bio-cremation during which all components of the body containment bag can effectively decompose by alkaline hydrolysis. Methods of making and of utilizing a body containment bag for decomposition are also disclosed.
