Aeroelastic Scaling of Flexible Wings Using Multi-Material Additive Manufacturing

Abstract

The potential applications of scaled flight test demonstrators to evaluate the aeroservoelastic performance of novel aircraft configurations using reduced dynamic response have attracted considerable attention in the aerospace industry. Full scale models are scaled down to reduce the experimental validation and evaluation costs. The flight test models may be manufactured using multi-material additive manufacturing techniques. To this end, dynamic and aeroelastic scaling using multi-material topology optimization is proposed. The optimization tool distributes materials within a structure to achieve the reduced eigenvalues and eigenvectors, while ensuring its manufacturability. The design domain would be a scaled model of the real full scale and it should have similar dynamic behavior as the full scaled models. The desired eigenvectors of the scaled models will be tracked by adding the modal assurance criterion as additional constraints in the formulation optimization. The continuous path planning will also be integrated into the multimaterial topology optimization for dynamic scaling to be employed in multi-material additive manufacturing.
