Abstract

Nonlinear Aeroelastic Framework for Multi-fidelity Analysis

Reference URL

N/A

Reasons and benefits of using JAXA Supercomputer System

Because high fidelity analysis is very expensive for simulation

Achievements of the Year

An unsteady vortex-lattice aerodynamic method and a fast unstructured CFD code are coupled with the structural model subject to the large deformations, providing different fidelity solutions.
