Development of innovative and optimized stiffeners run-out for overall panel weight saving of composite wing

The objective here is to develop the tools and the methodology to optimize the design of a stiffener run-out on a composite stiffened panel (stiffener geometry, thicknesses and lay-ups of different components, shape of the tapering). Based on mechanical test of typical configurations, both simulations and failure criteria will be developed for strength predictions capability. This development shall lead to a simple methodology dedicated to support the design of innovative and improved panel configurations taking into account the plain area as well as the stiffener run-out. The validation of optimised solutions will be supported by mechanical tests.
