AEROELASTIC OPTIMIZATION OF FUNCTIONALLY GRADED WINGS

Stability, Dynamic and Aeroelastic Optimization of Functionally Graded Composite Structures

Aeroelastic Analysis of Composite Wings

An aeroelastic stability analysis is presented for high-aspect ratio composite wings. The structural model is based on an asymptotically correct crosssectional formulation and a nonlinear geometric exact beam analysis, both derivable from 3-D elasticity. A new 2-D unsteady inflow finite-state theory is considered for the aerodynamic part of the solution. Theodorsen theory is also implemented an...

Maneuver Trim Optimization Techniques for Active Aeroelastic Wings

123 A new method for performing trim optimization of Active Aeroelastic Wing (AAW) technology is presented. The method is based on posing the trim problem as a linear program and solving it with the simplex method. Trim optimization is then integrated with the structural design process in a sequential manner, such that new optimal deflections of the control surfaces are computed for every struc...

Topology Optimization Design of Functionally Graded Structures

1. Abstract Functionally Graded Materials (FGMs) possess continuously graded material properties and are characterized by spatially varying microstructures. Such materials are studied in conjunction with the concept of topology optimization design which determines holes and connectivities of the structure by adding and removing material in the extended fixed design domain. The objective is to d...

Optimization of Functionally Graded Beams Resting on Elastic Foundations

In this study, two goals are followed. First, by means of the Generalized Differential Quadrature (GDQ) method, parametric analysis on the vibration characteristics of three-parameter Functionally Graded (FG) beams on variable elastic foundations is studied. These parameters include (a) three parameters of power-law distribution, (b) variable Winkler foundation modulus, (c) two-parameter elasti...
