An analytical procedure is developed for jet flapped wings, in which three-dimensional features of the trailing vortex system are represented. More conservative induced drag is predicted than by analyses based on the traditional planar vortex system. Illustrative examples are given showing that this method gives better agreement with measured drag than the planar-vortex methods.
