Continuous Dynamic Simulation of Nonlinear Aerodynamics/Nonlinear Structure Interaction (NANSI) for Morphing Vehicles.

摘要

In this report, we present the ZONA team's effort for this Phase II project. The ZONA team is made up of ZONA Technology. Inc. (ZONA), Arizona State University (Research Institute), and Professor Feng Liu (Consultant). The objective for this project was to develop a nonlinear aerodynamic and nonlinear structural interaction (NANSI) methodology as an expedient aeroelastic tool to handle continuous dynamic motion of morphing vehicles/wings from incompressible/subsonic to transonic flight regimes. The proposed vehicle for method demonstration was the Lockheed Folding wing (the Folding wing). Results showing the Flutter/LCO of the Folding wing in continuous pitching and the Finite Element Model (FEM) development/aeroelastic stability analysis of a morphing MAV, or the Gull wing/MAV, are presented.
