The beam model of a 3D wing is a natural extension of a widely used 2D 2-degree-of-freedom structure model and it considerably simplifies the structure analysis. Finite-volume unstructured CFD is used with the aim of applying various configurations in the future. The grid is dynamically deformed in accordance with the wing motion. A truss-analogy is applied to determine the new positions of interior points when the displacements of boundary points are specified. A well-known experiment using the AGARD standard aeroelastic configuration called 445.6 wing is selected for the validation. The developed methods successfully simulated the experimental flutter boundary., 資料番号: AA0049212015, レポート番号: JAXA-SP-05-017}, pages = {94--99}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {曲げ・捩り梁構造モデルと非構造CFDによる3次元翼フラッタ解析}, volume = {JAXA-SP-05-017}, year = {2006} }
