Yonago Convention Center BiG SHiP), Yonago, Tottori Japan, This paper is related to a two-dimensional numerical study about aerodynamic properties of airfoils in low Reynolds number flows. Four types of airfoils including a corrugated wing were selected for the computation and their aerodynamic features against both stationary and dynamic flow cases were examined. Even in a steady flow, there can generally be small unsteady fluctuations in aerodynamic coefficients, and it was identified that the corrugated wing alone exhibits a remarkable stability against such fluctuations. In the dynamic cases, the airfoils were given either heaving motion alone or heaving in combination with feathering motion. Results from the heaving case show that the corrugated wing yields the smallest fluctuations in drag and moment coefficients, indicating its being most stable among four. Results from heaving in combination with feathering case do not underline any apparent superiority of the corrugated wing to others but its characteristic behaviour was highlighted., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064967048, レポート番号: JAXA-SP-10-012}, pages = {277--282}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {A Numerical Study of Low Reynolds Unsteady Aerodynamics of a Corrugated Wing}, volume = {JAXA-SP-10-012}, year = {2011} }
