This paper is, therefore, intended as an investigation of the force generated and the flow around the wing when it undergoes unsteady movement at constant speed near the ground. And then it was proven that unsteady aerodynamic characteristics exist in the ground effect when moving in the direction of the height. The cause of these unsteady phenomena was the influence of the induced velocity. The induced velocity is derived from the starting vortex keeping on generating because the circulation around the wing continuously carried on changing when moving heightwise near the ground., 資料番号: AA0063908017, レポート番号: JAXA-SP-07-026E}, pages = {53--56}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Unsteady aerodynamic characteristics of wings in ground effect}, volume = {JAXA-SP-07-026E}, year = {2008} }
