However, very few experimental and theoretical studies have been reported. The aerodynamic characteristics of an HLFC airfoil and wing at high subsonic, high Reynolds number conditions have been investigated both numerically and experimentally. This paper reports the results of the wind tunnel test on drag characteristics, with and without suction, of two-dimensional HLFC airfoils with porous and slot suction approach under some adverse factors against laminar flow, and a numerical analysis of the wind tunnel data, which is based on the boundary layer calculation with a new transition prediction method allowed for the adverse factors and the Squire-Young drag formula. The HLFC models achieved total drag reduction of as high as 20 percent at realistic flight condition and the numerical method has given satisfactory predictions.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
