ANALYTICAL SENSITIVITY ANALYSIS FOR THE AEROELASTICAL EFFECTS OF COMPOSITE WING

The problem of aeroelastic behavior the wing made from composite material is investigated in this lecture.This paper presents a new analytical framework for the coupled optimization of aerostructural systems.The framework permits the use of analytical modeling of both the aerodynamics and the structures and represents our first step in an effort towards the development of a high-fidelity multidisciplinary optimization capability.6The approach is based on efficient analysis methodologies for the solution of the aerodynamics and structures subproblems, an adjoint solver to obtain aerodynamic sensitivities.In addition, simplified design examples are presented to illustrate the possible advantages of the new aero-structural design methodology in evaluating trade-offs between aerodynamic performance and structural weight for complete aircraft configurations.7The analytical methods for the bimodal dynamical instability are applied to study the nonconservative eigenvalue problem for governing equations.
