A new methodology for designing nonlinear aeroelastically scaled models is developed that uses direct matching of linear and nonlinear static responses, while simultaneously satisfying modal-frequency constraints. To demonstrate this technique, a one-ninth scaled vehicle is designed to match the nonlinear aeroelastic response of a full-scale joined-wing concept. This is the first demonstration of an optimization that simultaneously considers equivalent static loads for nonlinear statics and modal-frequency constraints. This is also the first scaling demonstration to include nonlinear aeroelastic verification. The results show marked improvement over the results from a scaled vehicle designed using a traditional method intended for linear applications.
