Keywords: noise control, flow control

Motivated by growing demands for aircraft noise reduction and for revolutionary new aerovehicle concepts, there is an increased emphasis on harnessing the potential of flow and noise control in a more fully integrated, multidisciplinary framework. At the same time, technologies for developing radically new aerovehicles, which promise quantum leap benefits in cost, safety and performance benefits with environmental friendliness, have appeared on the horizon. Transitioning new technologies to commercial applications will also require further advances in traditional areas of aeronautics. In these very fundamental ways, flow and noise control are being driven to be more closely linked during the early design phases of a vehicle concept for optimal and mutual noise and performance benefits.
