light data mentioned in the introduction to this paper. Tests of wings of 12 ft. span have also been made at speeds up to 100 M. P. H. A comparatively high Reynolds Number is thus attained. Figure 16 is a view of a wing set up for test. A comprehensive program of tests to determine the effect of… … Fig. 16 ACCURACY Dynamic pressure, thrust, torque, and R. P. M. are measured with an accuracy of from 1 to 2 per cent. Computed data are, therefore, correct to approximately plus or minus 2 per cent and final faired curves through computed points to about plus or minus 1 per cent. This compares…
