DU35 airfoil with an aspect ratio of 17. Original -180 to 180deg Cl, Cd, and Cm versus AOA data taken from Appendix A of DOWEC document 10046_009.pdf (numerical values obtained from Koert Lindenburg of ECN). Cl and Cd values corrected for rotational stall delay and Cd values corrected using the Viterna method for 0 to 90deg AOA by Jason Jonkman using AirfoilPrep_v2p0.xls. 1 Number of airfoil tables in this file 0.0 Table ID parameter 11.50 Stall angle (deg) 0.0 No longer used, enter zero 0.0 No longer used, enter zero 0.0 No longer used, enter zero -1.8330 Zero Cn angle of attack (deg) 7.1838 Cn slope for zero lift (dimensionless) 1.6717 Cn extrapolated to value at positive stall angle of attack -0.3075 Cn at stall value for negative angle of attack 0.00 Angle of attack for minimum CD (deg) 0.0094 Minimum CD value -180.00 0.000 0.0407 0.0000 -175.00 0.223 0.0507 0.0937 -170.00 0.405 0.1055 0.1702 -160.00 0.658 0.2982 0.2819 -155.00 0.733 0.4121 0.3213 -150.00 0.778 0.5308 0.3520 -145.00 0.795 0.6503 0.3754 -140.00 0.787 0.7672 0.3926 -135.00 0.757 0.8785 0.4046 -130.00 0.708 0.9819 0.4121 -125.00 0.641 1.0756 0.4160 -120.00 0.560 1.1580 0.4167 -115.00 0.467 1.2280 0.4146 -110.00 0.365 1.2847 0.4104 -105.00 0.255 1.3274 0.4041 -100.00 0.139 1.3557 0.3961 -95.00 0.021 1.3692 0.3867 -90.00 -0.098 1.3680 0.3759 -85.00 -0.216 1.3521 0.3639 -80.00 -0.331 1.3218 0.3508 -75.00 -0.441 1.2773 0.3367 -70.00 -0.544 1.2193 0.3216 -65.00 -0.638 1.1486 0.3054 -60.00 -0.720 1.0660 0.2884 -55.00 -0.788 0.9728 0.2703 -50.00 -0.840 0.8705 0.2512 -45.00 -0.875 0.7611 0.2311 -40.00 -0.889 0.6466 0.2099 -35.00 -0.880 0.5299 0.1876 -30.00 -0.846 0.4141 0.1641 -25.00 -0.784 0.3030 0.1396 -24.00 -0.768 0.2817 0.1345 -23.00 -0.751 0.2608 0.1294 -22.00 -0.733 0.2404 0.1243 -21.00 -0.714 0.2205 0.1191 -20.00 -0.693 0.2011 0.1139 -19.00 -0.671 0.1822 0.1086 -18.00 -0.648 0.1640 0.1032 -17.00 -0.624 0.1465 0.0975 -16.00 -0.601 0.1300 0.0898 -15.00 -0.579 0.1145 0.0799 -14.00 -0.559 0.1000 0.0682 -13.00 -0.539 0.0867 0.0547 -12.00 -0.519 0.0744 0.0397 -11.00 -0.499 0.0633 0.0234 -10.00 -0.480 0.0534 0.0060 -5.54 -0.385 0.0245 -0.0800 -5.04 -0.359 0.0225 -0.0800 -4.54 -0.360 0.0196 -0.0800 -4.04 -0.355 0.0174 -0.0800 -3.54 -0.307 0.0162 -0.0800 -3.04 -0.246 0.0144 -0.0800 -3.00 -0.240 0.0240 -0.0623 -2.50 -0.163 0.0188 -0.0674 -2.00 -0.091 0.0160 -0.0712 -1.50 -0.019 0.0137 -0.0746 -1.00 0.052 0.0118 -0.0778 -0.50 0.121 0.0104 -0.0806 0.00 0.196 0.0094 -0.0831 0.50 0.265 0.0096 -0.0863 1.00 0.335 0.0098 -0.0895 1.50 0.404 0.0099 -0.0924 2.00 0.472 0.0100 -0.0949 2.50 0.540 0.0102 -0.0973 3.00 0.608 0.0103 -0.0996 3.50 0.674 0.0104 -0.1016 4.00 0.742 0.0105 -0.1037 4.50 0.809 0.0107 -0.1057 5.00 0.875 0.0108 -0.1076 5.50 0.941 0.0109 -0.1094 6.00 1.007 0.0110 -0.1109 6.50 1.071 0.0113 -0.1118 7.00 1.134 0.0115 -0.1127 7.50 1.198 0.0117 -0.1138 8.00 1.260 0.0120 -0.1144 8.50 1.318 0.0126 -0.1137 9.00 1.368 0.0133 -0.1112 9.50 1.422 0.0143 -0.1100 10.00 1.475 0.0156 -0.1086 10.50 1.523 0.0174 -0.1064 11.00 1.570 0.0194 -0.1044 11.50 1.609 0.0227 -0.1013 12.00 1.642 0.0269 -0.0980 12.50 1.675 0.0319 -0.0953 13.00 1.700 0.0398 -0.0925 13.50 1.717 0.0488 -0.0896 14.00 1.712 0.0614 -0.0864 14.50 1.703 0.0786 -0.0840 15.50 1.671 0.1173 -0.0830 16.00 1.649 0.1377 -0.0848 16.50 1.621 0.1600 -0.0880 17.00 1.598 0.1814 -0.0926 17.50 1.571 0.2042 -0.0984 18.00 1.549 0.2316 -0.1052 19.00 1.544 0.2719 -0.1158 19.50 1.549 0.2906 -0.1213 20.00 1.565 0.3085 -0.1248 21.00 1.565 0.3447 -0.1317 22.00 1.563 0.3820 -0.1385 23.00 1.558 0.4203 -0.1452 24.00 1.552 0.4593 -0.1518 25.00 1.546 0.4988 -0.1583 26.00 1.539 0.5387 -0.1647 28.00 1.527 0.6187 -0.1770 30.00 1.522 0.6978 -0.1886 32.00 1.529 0.7747 -0.1994 35.00 1.544 0.8869 -0.2148 40.00 1.529 1.0671 -0.2392 45.00 1.471 1.2319 -0.2622 50.00 1.376 1.3747 -0.2839 55.00 1.249 1.4899 -0.3043 60.00 1.097 1.5728 -0.3236 65.00 0.928 1.6202 -0.3417 70.00 0.750 1.6302 -0.3586 75.00 0.570 1.6031 -0.3745 80.00 0.396 1.5423 -0.3892 85.00 0.237 1.4598 -0.4028 90.00 0.101 1.4041 -0.4151 95.00 -0.022 1.4053 -0.4261 100.00 -0.143 1.3914 -0.4357 105.00 -0.261 1.3625 -0.4437 110.00 -0.374 1.3188 -0.4498 115.00 -0.480 1.2608 -0.4538 120.00 -0.575 1.1891 -0.4553 125.00 -0.659 1.1046 -0.4540 130.00 -0.727 1.0086 -0.4492 135.00 -0.778 0.9025 -0.4405 140.00 -0.809 0.7883 -0.4270 145.00 -0.818 0.6684 -0.4078 150.00 -0.800 0.5457 -0.3821 155.00 -0.754 0.4236 -0.3484 160.00 -0.677 0.3066 -0.3054 170.00 -0.417 0.1085 -0.1842 175.00 -0.229 0.0510 -0.1013 180.00 0.000 0.0407 0.0000
