Abstract

A skin for an aircraft is configured to be disposed on a first rigid member and on a second rigid member. The second rigid member is movable with respect to the first rigid member and a distance is defined between the first rigid member and the second rigid member. A morphing member of the skin extends between the first rigid member and the second rigid member. The morphing member comprises first segments forming a first portion attached to the first rigid member and second segments forming a second portion attached to the second rigid member. The first and second portions are separated along a substantially linear seam in the absence of change in the distance and an orientation between the first rigid member and the second rigid member.

First claim

What is claimed is:

1. An aircraft skin assembly, the skin assembly comprising: a first rigid member, wherein the first rigid member comprises at least a portion of an aircraft structural frame; a second rigid member, wherein the second rigid member also comprises at least a portion of the aircraft structural frame, wherein the second rigid member is moveable with respect to the first rigid member, and wherein a distance is defined between the first rigid member and the second rigid member; a morphing member extending between the first rigid member and the second rigid member, wherein the morphing member compensates for at least one of a change in the distance and a change in an orientation between the first rigid member and the second rigid member; wherein the morphing member comprises: a plurality of first segments attached to the first rigid member; and a plurality of second segments attached to the second rigid member; wherein the first segments are moveable with respect to one another, wherein the second segments are moveable with respect to one another, wherein the first segments form a first portion and the second segments form a second portion and said portions are separated from one another along a substantially linear seam in the absence of change in the distance and the orientation between the first rigid member and the second rigid member.

2. The aircraft skin assembly of claim 1 , wherein: the first segments are in register with corresponding ones of the second segments, the first segments are slidingly disposed adjacent to the second segments, and the first segments overlap the second segments.

3. The aircraft skin assembly of claim 1 , wherein the first segments and the second segments comprise at least one of aluminum, an alloy of aluminum, beryllium, an alloy of beryllium, magnesium, an alloy of magnesium, iron, an alloy of iron, polymers, ceramics, and composite materials.
