wing ribs and spars

endobj Not a lot of commentary, so I'll just get to the pictures. By analogy with the anatomical definition of "rib", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing. I'm curious if there's something in the Citabria wing design that is causing the spars to crack. endobj In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction.. By analogy with the anatomical definition of "rib", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing.Usually ribs incorporate the airfoil shape of the wing, and the skin adopts this shape when stretched over the ribs. Stress and fatigue analysis of the whole wing section is carried out to compute the stresses and life at spars and ribs due to the applied pressure load. 2 0 obj Due to the ribs, which add a spanwise component to the stress in the membrane, the true shape will be somewhere in between the 100% and the 0% shape.
