Calculation of lift-curve slope using a wing tip biased vortex distribution

The horseshoe vortex model presently used to calculate the lift-curve slope of a flat, untwisted rectangular wing is based on wingtip-biased cascades of vortices modifying a central vortex core. If the cascades are confined to the outer portions of the wing, the lift-curve slope may be calculated to an adequate degree of accuracy over a broad range of aspect ratios, using seven vortex elements. The resulting aerodynamic calculations are not computationally intensive, and attempt to model the qualitative properties of the flow. (O.C.)
