dc.description.abstractIn the present study, the aeroelastic energy response of a twin-engine composite wing system is optimized based onsequential quadratic programming (SQP) method. The variable stiffness is acquired by constructing laminates of thin wallbeam (TWB) with curvilinear fibers having prescribed paths. In order to account the effect of spanwise locations andmass of the engines on the aeroelastic characteristics of TWB, the novel governing equations of motion are obtained usingHamilton's variational principle. The paper aims to exploit desirable fiber paths with improved aeroelastic properties fordifferent twin-engine wing configuration. Ritz based solution methodology is employed to solve the equations withcoupled incompressible unsteady aerodynamic model based on Wagner’s function. A novel optimization strategy basedon the total energy of the aeroelastic system is introduced. The proposed total energy, as a cost function, is minimized interms of four optimization variables of two engine’s locations and wing structure curvilinear fiber angle with two designparameters. The total energy is obtained by integrating responses of kinetic and potential energy in a specific time interval.The minimum total energy is an indication of ideal optimization variables which leads to the optimum flutter performance.Numerical results demonstrate the effectiveness of the optimization variables on the total energy of the aeroelastic systemand determine the optimal values of introduced variables in case of minimum total energy and improved aeroelasticcharacteristics.
