11 JOINT REPORT ON STANDARDIZATION TESTS DISCUSSION OF TEST DATA Consider the first group consisting of tests made at speeds between 29.3 and 40 ft. per sec. The polar plot of drag uncorrected for wall effect is given on Figure 8. The same data corrected for wall effect arc plotted on Figure 1).… … .32 .28 .24 .20 .16 .12 CD' .08 .04 0 16° 20° 12° 4° 8° -4° or Figure 11 effect correction results in better agreement. The same conclusion may be reached from a study of these data plotted against angle of attack as in Figures 10 and 11 The second group of tests were made at speeds between 57.5…
