Structural ribs for providing structural support for a structure, such as the pressure cabin of a blended-wing body aircraft. In a first embodiment, the ribs are generally "Y-shaped", being comprised of a vertical web and a pair of inclined webs attached to the vertical web to extend upwardly and outwardly from the vertical web in different directions, with only the upper edges of the inclined webs being attached to a structural element. In a second embodiment, the ribs are generally "trident-shaped", whereby the vertical web extends upwardly beyond the intersection of the inclined webs with the vertical web, with the upper edge of the vertical web as well as the upper edges of the inclined webs being attached to the same structural element.

[ What is claimed is:] [1.] A rib for providing structural support for a non-cylindrical pressure cabin structure of an aircraft which includes vertically spaced-apart first and second structural elements, the rib comprising:a vertical web positioned and oriented vertically between the first structural element and the second structural element, and the vertical web having a top edge and a bottom edge; andfirst and second inclined webs each having respective upper and lower edges, wherein the upper edges of the first and second inclined webs are attached to a lower side of the second structural element, and the lower edges of the first and second inclined webs intersect and are attached to the upper edge of the vertical web at an intersection therewith spaced from and located between the first structural element and the second structural element, wherein the first and second inclined webs extend upwardly and outwardly from the intersection with the vertical web in different directions, and wherein the vertical web includes a segment extending straight downward from the intersection with the first and second inclined webs until the bottom edge of the vertical web is attached directly to a top side of the first structural element wherein the segment is devoid of inclined webs connected to the first structural element, whereby the resulting rib is generally Y-shaped.
