A beam blade windshield wiper assembly (10; 110) for use in connection with an automotive vehicle comprising: a wiping element (18; 118) adapted to substantially contact a surface to be wiped within a predetermined attack angle range that is ±10° perpendicular relative to the surface to be wiped; at least one resiliently flexible elongated beam (36A, 36B; 136) that is operatively engaged to said wiping element (18; 118) and adapted to apply a downward force to said wiping element (18; 118); a connecting member (38; 138) that is mounted to said at least one elongated beam (36A, 36B; 136) and adapted to releasably connect to a wiper arm; an airfoil (44; 144) having an attachment portion (46; 146) that is operatively attached to said at least one elongated beam (36A, 36B; 136) and an upper portion (48; 148) that is operatively attached to said attachment portion (46; 146), said upper portion (48; 148) including a wing (68; 168) having a facing surface (70; 170) and a trailing surface (72; 172) that extend outwardly from said upper portion (48; 148) at predetermined converging angles, characterized in that said facing surface (70; 170) is generally planar and extends outwardly from said upper portion (48; 148) at a predetermined angle of 45° (±1°) relative to a horizontal axis defined by said at least one elongated beam (36A, 36B; 136) to provide a facing surface layover angle range of 35° to 55° (±1°) throughout said attack angle range and said upper portion (48; 148) further including a contoured lead surface (64; 164) adjacent to said planar facing surface (70; 170) to transfer airflow toward said wing (68; 168), said contoured lead surface (64; 164) having an outwardly convex section (65; 165) in distal relation relative to said wing (68; 168) and a concave depressed section (66; 166) disposed adjacent to said outwardly convex section (65; 165) and in proximate relation relative to said wing (68; 168), wherein said wing (68; 168) and said contoured lead surface (64; 164) cooperate to increase the downward force acting on said airfoil (44; 144) during operational movement across the surface to be wiped for improved wind lift resistance and reduced drag. a wiping element (18; 118) adapted to substantially contact a surface to be wiped within a predetermined attack angle range that is ±10° perpendicular relative to the surface to be wiped; at least one resiliently flexible elongated beam (36A, 36B; 136) that is operatively engaged to said wiping element (18; 118) and adapted to apply a downward force to said wiping element (18; 118); a connecting member (38; 138) that is mounted to said at least one elongated beam (36A, 36B; 136) and adapted to releasably connect to a wiper arm; an airfoil (44; 144) having an attachment portion (46; 146) that is operatively attached to said at least one elongated beam (36A, 36B; 136) and an upper portion (48; 148) that is operatively attached to said attachment portion (46; 146), said upper portion (48; 148) including a wing (68; 168) having a facing surface (70; 170) and a trailing surface (72; 172) that extend outwardly from said upper portion (48; 148) at predetermined converging angles, characterized in that said facing surface (70; 170) is generally planar and extends outwardly from said upper portion (48; 148) at a predetermined angle of 45° (±1°) relative to a horizontal axis defined by said at least one elongated beam (36A, 36B; 136) to provide a facing surface layover angle range of 35° to 55° (±1°) throughout said attack angle range and said upper portion (48; 148) further including a contoured lead surface (64; 164) adjacent to said planar facing surface (70; 170) to transfer airflow toward said wing (68; 168), said contoured lead surface (64; 164) having an outwardly convex section (65; 165) in distal relation relative to said wing (68; 168) and a concave depressed section (66; 166) disposed adjacent to said outwardly convex section (65; 165) and in proximate relation relative to said wing (68; 168), wherein said wing (68; 168) and said contoured lead surface (64; 164) cooperate to increase the downward force acting on said airfoil (44; 144) during operational movement across the surface to be wiped for improved wind lift resistance and reduced drag.
