ABSTRACT:
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.
