7 THE EFFECTS OF SHIELDING THE TIPS OF AUiFOILS the aspect ratio is: Calculated on this basis, the following results are obtained: Speed range 5 4 3 2 I … Fig. i2 It is also interesting to note that the Prandtl-Munk formula, dC,_ 2ir OA 294 which expresses the relation of lift curve slope to aspect ratio, gives much lower values for the apparent aspect ratio." The computed values are: By shifting the polar of the airfoil with (mkI plates along the…
