This work presents the results of aeroelastic optimisations of a LH2 powered strut-braced aircraft configuration. The influence of the strut under aeroelastic loads and especially how some geometries introduce in-plane bending and buckling issues (for negative loadcases) is studied . Flutter is also checked to ensure it does not appear within the flight enveloppe.
