Bladders, storage containers, and aircraft fuel systems

摘要

A storage container, which may be a fuel bladder, includes a container wall configured to retain a fluid within the container and an opening through the container wall. The container includes a rim of the container wall surrounding the opening and a non-planar flex region of the container wall adjacent to the rim. The flex region includes at least one resilient crease in the container wall and the rim is between the flex region and the opening. A portion of the container wall surrounds the flex region. The flex region exhibits the property of allowing movement of the rim with respect to the portion of the container wall.

1. A fuel bladder comprising:
two sections co-planar with one another; and a non-planar flex region separating the two co-planar sections and exhibiting the property of allowing movement of the bladder relative to an external bladder attachment, the two co-planar sections and the non-planar flex region being directly connected to one another or integrally formed, the two co-planar sections and the non-planar flex region containing the same material, and the non-planar flex region extending radially between the two co-planar sections of the fuel bladder, wherein the fuel bladder is comprised by an aircraft fuel system.
