Title: Nonlinear AeroServoElastic Reduced Order Model for Active Structural Control
Agency: NASA
Contract: NNX12CD51P
Award Amount: $124,930.00


The overall goal of the proposed effort is to develop and demonstrate rigorous model order reduction (MOR) technologies to automatically generate fully coupled, nonlinear, parameterized aeroservoelastic reduced-order models (ROMs) for smart material-based active structural control. The Phase I effort will focus on developing constituent nonlinear ROMs for aerodynamics, structural dynamics, and electromechanics of the smart materials, as well as an integration scheme for coupled aerodynamic, structural, and electromechanical analysis. A modular software framework enabling automated data exchange, ROM generation and computation, as well as verification will also be constructed. The feasibility of the proposed technologies will be demonstrated for several aeroservoelasticity test problems of NASA interest (including NASA's Aerostructures Test Wing.) The Phase II effort will focus on: (1) algorithm improvement in terms of execution efficiency, model parameterization, and automated parameter selection; and (2) software environment enhancement (such as developing a direct interface to NASA-relevant simulation tools, fully automated ROM process including data exchange, ROM generation and computation, and verification) and extensive technology demonstration in complex configurations and temporally varying operations.
