Optimization of Supersonic Aircraft Wing-Box using Curvilinear SpaRibs
… of using curvilinear spars and ribs, termed SpaRibs, to design supersonic aircraft wing-box in comparison to the use of classic design concepts that employ straight spars and ribs. The intent is to achieve a more efficient load-bearing mechanism and to passively control aeorelastic behavior …

Optimal Design and Analysis of Bio-inspired, Curvilinearly Stiffened Composite Flexible Wings
… aircraft wing design. The biologically inspired SpaRibs concept is used for aircraft wing box internal structural layout design to achieve the optimal stiffness distribution to improve the aircraft performance. Along with the use of the active aeroelastic wing concept through morphing wing shape …
