초록

A jet pipe wall is made from a honeycomb sandwich structure in which the skin forming one side of the sandwich is cut into many small square sheet pieces so that when differential longitudinal expansion occurs between the skins as a result of lying in fluid flows of differing temperature, the total shear felt by the honeycomb is divided equally between those areas of honeycomb covered by respective small sheet pieces, so that the overall shear effect is reduced.

청구항

An improved sound absorbing sandwich structure for use in environments where a temperature differential across the structure thickness causes differential expansion and movement of the layers with respect to each other, the structure comprising: a first sheet metal layer, a second sheet metal layer having perforations therein, a rigid honeycomb cellular interlayer disposed between said first and second layers, and means rigidly attaching said interlayer by welding to each of said first layer and said second layer to provide a substantially rigid sandwich...
