Book excerpt: A theoretical method based on slender-body theory is presented for the stepwise calculation of vortex paths in the presence of wing-body combinations and the determination of the load distributions, forces, and moments on the combinations due to the vortices. Comparisons of calculated and experimental results indicate that the vortex paths and the forces induced by the vortices can be closely predicted by the calculative method only for slender configurations. The total forces and moments, however, in many cases can be predicted adequately for nonslender as well as slender triangular-wing configurations.
