Modern-day aircraft employ in the design stage a multidisciplinary process which involves the integration of several disciplines such as aerodynamics, structures, dynamics and controls. Structural optimization is performed to obtain minimum weight for improved performance of the aircraft at minimum cost. Weight reduction can also be achieved by optimizing the structure to meet flutter requirements and still be consistent with such requirements as strength and size constraints. Structural optimization generally involves definition of an objective function and a set of constraints as functions of the design variables. The weight is usually the objective function and the constraints are stresses, displacements, and aeroelastic instabilities such as flutter or divergence speed.
