An analysis has been developed for high-aspect-ratio jet-flap wings of arbitrary geometry and blowing. It appears that the present method is as accurate as other known methods and is flexible and rapid, particularly for discontinuous planforms. Although definitive test data are lacking, correlation with existing experimental data is satisfactory. To properly evaluate jet-flap theories, it is recommended that definitive lifting-surface analyses be developed and properly controlled and corrected experiments conducted, including cases with discontinuous parameters. Finally, it is believed that the present method is a useful analytical tool for jet-flap wing design.
