Outline of Final Research Achievements

Wind tunnel experiment has been performed to investigate the aerodynamic characteristics of a novel aerodynamic device called "vertical aileron" which is a control surface attached vertically over the main wing of an aircraft. Not only the parameters to define the planform of the vertical aileron, but also the location where the vertical aileron attached to the main wing are the important design parameters. Especially, the aerodynamic performance seems to be sensitive to the chordwise location relative to the main wing. Based on this results, we have applied the vertical aileron to control the lift during the presence of gust in horizontal direction, and have shown that lift can be maintained constant. Therefore, vertical aileron is a good candidate to be used as a new aerodynamic device to control the aerodynamic variation due to gust.
