    Abstract: An aircraft fuel system includes one or more fuel cells adapted to contain fuel, a fuel cell receiving assembly having an inner surface adapted to receive the one or more fuel cells and a fuel cell cushion disposed between the inner surface of the fuel cell receiving assembly and the one or more fuel cells. The fuel cell cushion is machined from a foam substrate to form a shaped foam substrate that is substantially covered with a cushion coating. The cushion coating is sprayable onto the shaped foam substrate such that the fuel cell cushion is substantially nonabsorbent of fuel. The fuel cell cushion is interposable between the inner surface of the fuel cell receiving assembly and the one or more fuel cells to cushion the one or more fuel cells from damage.

    Abstract: An embodiment rotorcraft structure includes a step disposed at an exterior of the rotorcraft, and an emergency kit installed into the recess of the step. The step is faired into a skin on the exterior of the rotorcraft. The emergency kit includes a container and a life raft. The container includes a container body that has a storage cavity, a container panel, and a first attachment element. The container body is disposed in the recess of the step, attached to the step, and has a storage cavity. The container panel is disposed at a bottom of the storage cavity, and the life raft is disposed in the storage cavity. The first attachment element releasably couples a first edge of the container panel to the container body, and encloses the life raft in the container under the step.
