Method for Calculating Wing Characteristics by Lifting-Line Theory Using Nonlinear Section Lift Data

摘要

Material from various sources is combined with some original work into the method of calculating wing characteristics by lifting-line theory. Multhopp's systems of multipliers are employed to obtain the induced angle of attack directly from the spanwise lift distribution. Detailed examples are given for symmetrical lift distribution. Wing characteristics calculated from general nonlinear lift data have been found to agree much closer with experimental data in the region of maximum lift than those calculated on the consumption of linear section lift curves.
