Theoretical Basic Span Loading Characteristics of Wings With Arbitrary Sweep, Aspect Ratio, and Taper Ratio
Abstract
A procedure based on the Weissinger method has been devised so that the basic span loading and associated aerodynamic characteristics can be rapidly predicted for wings having arbitrary values of sweep, aspect ratio, taper ratio, and twist. A method for correcting for the effects of compressibility is given. A comparison of the results of this method with that of lifting-line and lifting-surface method indicates that the accuracy is much better than that obtained with lifting-line methods and is comparable to that obtained with lifting-surface methods. This report, together with NACA TN No. 1491, allows a simple and rapid prediction of both the basic and additional loading characteristics for wings of arbitrary plan form. It is believed the predicted values are valid at all subcritical Mach numbers and for all lift coefficients where viscous and stall effects are negligible. To establish the effects of sweep, aspect ratio, and taper ratio on the basic loading characteristics produced by uniform twist, the method presented in this report was applied to a few representative wing configurations and the results discussed.
