Radially oriented honeycomb and structures formed therefrom

A structure comprising a wall,

• the wall defining a radius of curvature and comprising a radially oriented strip that includes a first edge at an inner surface of the wall and a second edge at an outer surface of the wall,
• the strip defining an array of cells, each cell having a cell length extending from the first edge to the second edge in the radial direction of the wall curvature, and
• each cell defining a first unit cell profile comprising a first geometric shape at the first edge and a second, different unit cell profile comprising a second, different geometric shape at the second edge, the first unit cell profile transitioning to the second unit cell profile across the cell length;
• wherein the length of the second edge along the second unit cell profile is substantially equal to the length of the first edge along the first unit cell profile,
• wherein at least one of the first and second geometric shapes comprises a sine wave, wherein the radially oriented strip exhibits a radial curvature due to the change in the different unit cell profiles across a width of the radially oriented strip, and
• wherein the radially oriented strip spirals about an axis of the radius of curvature of the wall such that the strip forms a plurality of layers of the wall.
