DU25 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 8.50 Stall angle (deg) 0.0 No longer used, enter zero 0.0 No longer used, enter zero 0.0 No longer used, enter zero -4.2422 Zero Cn angle of attack (deg) 6.4462 Cn slope for zero lift (dimensionless) 1.4336 Cn extrapolated to value at positive stall angle of attack -0.6873 Cn at stall value for negative angle of attack 0.00 Angle of attack for minimum CD (deg) 0.0065 Minimum CD value -180.00 0.000 0.0202 0.0000 -175.00 0.368 0.0324 0.1845 -170.00 0.735 0.0943 0.3701 -160.00 0.695 0.2848 0.2679 -155.00 0.777 0.4001 0.3046 -150.00 0.828 0.5215 0.3329 -145.00 0.850 0.6447 0.3540 -140.00 0.846 0.7660 0.3693 -135.00 0.818 0.8823 0.3794 -130.00 0.771 0.9911 0.3854 -125.00 0.705 1.0905 0.3878 -120.00 0.624 1.1787 0.3872 -115.00 0.530 1.2545 0.3841 -110.00 0.426 1.3168 0.3788 -105.00 0.314 1.3650 0.3716 -100.00 0.195 1.3984 0.3629 -95.00 0.073 1.4169 0.3529 -90.00 -0.050 1.4201 0.3416 -85.00 -0.173 1.4081 0.3292 -80.00 -0.294 1.3811 0.3159 -75.00 -0.409 1.3394 0.3017 -70.00 -0.518 1.2833 0.2866 -65.00 -0.617 1.2138 0.2707 -60.00 -0.706 1.1315 0.2539 -55.00 -0.780 1.0378 0.2364 -50.00 -0.839 0.9341 0.2181 -45.00 -0.879 0.8221 0.1991 -40.00 -0.898 0.7042 0.1792 -35.00 -0.893 0.5829 0.1587 -30.00 -0.862 0.4616 0.1374 -25.00 -0.803 0.3441 0.1154 -24.00 -0.792 0.3209 0.1101 -23.00 -0.789 0.2972 0.1031 -22.00 -0.792 0.2730 0.0947 -21.00 -0.801 0.2485 0.0849 -20.00 -0.815 0.2237 0.0739 -19.00 -0.833 0.1990 0.0618 -18.00 -0.854 0.1743 0.0488 -17.00 -0.879 0.1498 0.0351 -16.00 -0.905 0.1256 0.0208 -15.00 -0.932 0.1020 0.0060 -14.00 -0.959 0.0789 -0.0091 -13.00 -0.985 0.0567 -0.0243 -13.00 -0.985 0.0567 -0.0243 -12.01 -0.953 0.0271 -0.0349 -11.00 -0.900 0.0303 -0.0361 -9.98 -0.827 0.0287 -0.0464 -8.98 -0.753 0.0271 -0.0534 -8.47 -0.691 0.0264 -0.0650 -7.45 -0.555 0.0114 -0.0782 -6.42 -0.413 0.0094 -0.0904 -5.40 -0.271 0.0086 -0.1006 -5.00 -0.220 0.0073 -0.1107 -4.50 -0.152 0.0071 -0.1135 -4.00 -0.084 0.0070 -0.1162 -3.50 -0.018 0.0069 -0.1186 -3.00 0.049 0.0068 -0.1209 -2.50 0.115 0.0068 -0.1231 -2.00 0.181 0.0068 -0.1252 -1.50 0.247 0.0067 -0.1272 -1.00 0.312 0.0067 -0.1293 -0.50 0.377 0.0067 -0.1311 0.00 0.444 0.0065 -0.1330 0.50 0.508 0.0065 -0.1347 1.00 0.573 0.0066 -0.1364 1.50 0.636 0.0067 -0.1380 2.00 0.701 0.0068 -0.1396 2.50 0.765 0.0069 -0.1411 3.00 0.827 0.0070 -0.1424 3.50 0.890 0.0071 -0.1437 4.00 0.952 0.0073 -0.1448 4.50 1.013 0.0076 -0.1456 5.00 1.062 0.0079 -0.1445 6.00 1.161 0.0099 -0.1419 6.50 1.208 0.0117 -0.1403 7.00 1.254 0.0132 -0.1382 7.50 1.301 0.0143 -0.1362 8.00 1.336 0.0153 -0.1320 8.50 1.369 0.0165 -0.1276 9.00 1.400 0.0181 -0.1234 9.50 1.428 0.0211 -0.1193 10.00 1.442 0.0262 -0.1152 10.50 1.427 0.0336 -0.1115 11.00 1.374 0.0420 -0.1081 11.50 1.316 0.0515 -0.1052 12.00 1.277 0.0601 -0.1026 12.50 1.250 0.0693 -0.1000 13.00 1.246 0.0785 -0.0980 13.50 1.247 0.0888 -0.0969 14.00 1.256 0.1000 -0.0968 14.50 1.260 0.1108 -0.0973 15.00 1.271 0.1219 -0.0981 15.50 1.281 0.1325 -0.0992 16.00 1.289 0.1433 -0.1006 16.50 1.294 0.1541 -0.1023 17.00 1.304 0.1649 -0.1042 17.50 1.309 0.1754 -0.1064 18.00 1.315 0.1845 -0.1082 18.50 1.320 0.1953 -0.1110 19.00 1.330 0.2061 -0.1143 19.50 1.343 0.2170 -0.1179 20.00 1.354 0.2280 -0.1219 20.50 1.359 0.2390 -0.1261 21.00 1.360 0.2536 -0.1303 22.00 1.325 0.2814 -0.1375 23.00 1.288 0.3098 -0.1446 24.00 1.251 0.3386 -0.1515 25.00 1.215 0.3678 -0.1584 26.00 1.181 0.3972 -0.1651 28.00 1.120 0.4563 -0.1781 30.00 1.076 0.5149 -0.1904 32.00 1.056 0.5720 -0.2017 35.00 1.066 0.6548 -0.2173 40.00 1.064 0.7901 -0.2418 45.00 1.035 0.9190 -0.2650 50.00 0.980 1.0378 -0.2867 55.00 0.904 1.1434 -0.3072 60.00 0.810 1.2333 -0.3265 65.00 0.702 1.3055 -0.3446 70.00 0.582 1.3587 -0.3616 75.00 0.456 1.3922 -0.3775 80.00 0.326 1.4063 -0.3921 85.00 0.197 1.4042 -0.4057 90.00 0.072 1.3985 -0.4180 95.00 -0.050 1.3973 -0.4289 100.00 -0.170 1.3810 -0.4385 105.00 -0.287 1.3498 -0.4464 110.00 -0.399 1.3041 -0.4524 115.00 -0.502 1.2442 -0.4563 120.00 -0.596 1.1709 -0.4577 125.00 -0.677 1.0852 -0.4563 130.00 -0.743 0.9883 -0.4514 135.00 -0.792 0.8818 -0.4425 140.00 -0.821 0.7676 -0.4288 145.00 -0.826 0.6481 -0.4095 150.00 -0.806 0.5264 -0.3836 155.00 -0.758 0.4060 -0.3497 160.00 -0.679 0.2912 -0.3065 170.00 -0.735 0.0995 -0.3706 175.00 -0.368 0.0356 -0.1846 180.00 0.000 0.0202 0.0000
