Results are reported on the modification of the wing download due to a rotor wake interaction, using surface blowing. Previously, the wake/wing interaction flowfield has been studied qualitatively and quantitatively using surface pressure fields and off-surface velocity fields. The development of spanwise flows had been shown, along with the effects on surface pressure and download and when a trailing edge flap was deflected. New results on the redirection of the wake, using surface blowing, show a 20% improvement in the effect of the flaps in reducing the download.
