| Outline of Final Research Achievements |
This group has been developing the airfoil stall suppression system by utilizing the bubble burst control plate, which enables to increase the airfoil stall angle of attack by controlling the laminar separation bubble which is known to be the cause of the airfoil stall. In this research, an autonomous actuator system which automatically adjusts the height of the plate following to the increment or decrement of the angle of attack was created and its effectiveness was confirmed. Furthermore, the effectiveness of the bubble burst control plate at higher Reynolds number was investigated and the criteria which can determine the optimum height and location of the plate were created.
