The symbol of the Hessian for a static aeroelastic optimization model problem is analyzed for the optimization of a plate's shape and rigidity distribution with respect to a given cost function. The flow is modeled by the small-disturbance full-potential equation, and the structure is modeled by an isotropic (von Kármán) plate equation. The cost function consists of both aerodynamic and structural terms. Applications to optimization strategies are discussed and demonstrated numerically.
