Active Flow

The design, fabrication and installation of an approximately 1/6 scale model of an aircraft vertical stabilizer for research in Active Flow Control (AFC) is discussed. Highlighted are the unique design requirements of wind tunnel models, the specialized fabrication techniques employed to create them and the required close collaboration between industry, government and three academic institutions. The design of the model involves often competing constraints imposed by structural, instrumentation, aerodynamic, manufacturability and research-agenda considerations as well as cost and schedule. Instrumentation requires hundreds of pressure ports and six-axis force/torque sensing. Aerodynamic considerations necessitate high manufacturing precision, highly-skilled fabrication techniques and careful observance of model geometry throughout the design and fabrication processes. A scale model of a vertical stabilizer for AFC research was successfully designed, fabricated and deployed. The collaboratively designed model satisfies the structural, aerodynamic and research design constraints, and furthers the state of the art in Active Flow Control research.

Active Flow

In the recent decade, a great deal of research has been devoted to active control of the unsteady flow in a wide variety of components and/or subsystems of aircraft, automobile and marine vehicles and industrial fluid machinery, because small improvements in component and/or subsystem performance often lead to large payoffs. The term active flow control is used to describe the methods to actively manipulate flow fields with auxiliary power introduced to the flow. In this paper, a brief survey of the recent progress in active flow control research is made. The possibilities of further performance improvement using the theories and technologies of intelligent systems are discussed. Intelligent systems can be applied to improve sensing and actuating, increase model accuracy, and optimize the control schemes. The active flow control systems, on the other hand, may also challenge intelligent systems researchers and stimulate new development of intelligent tools.
