Advanced Diagnostics and Smart Morphing Flow Control for Unsteady Aerodynamics Applications
Abstract
An unsteady aerodynamics investigation using advanced optical diagnostics andcomputational fluid dynamics (CFD) is proposed for rotary-wing active flow control using smartmaterial actuators. Advanced diagnostics including tomographic (three-dimensional 3D)Particle Image Velocimetry (3DPIV) and Pressure and Temperature Sensitive Paints (PSP/TSP)and CFD techniques are proposed for providing the understanding of the basic unsteady andturbulence structures interactions with morphing airfoil surfaces. A closed loop feedback controlis then proposed to actuate the wing for various unsteady and turbulent conditions so that its shapeadjusts itself for optimal aerodynamics. This investigation would lead to understanding newmechanisms for increasing aircraft range, reduce drag, and enhance lift, while reducing directoperating cost through improved cruise efficiency. Smart active flow control would supportmissions such as external lift of increasing payload weights, increased altitude operations inmountainous regions, and adaptive maneuverability within highly unsteady flows such as those ofthe ship airwakes encountered during shipboard landings.
