Developing a virtual stiffness-damping system for airfoil aeroelasticity testing

In this research a two-degrees-of-freedom (2-DOF) virtual stiffness-damping system (VSDS) is developed to facilitate industrial and laboratory testing of airfoil aeroelasticity instability. Other existing test-beds in this field rely on elastic elements or structures to set airfoil elasticity in tests, which can be costly and inconvenient in cases of frequent stiffness adjustment across a wide range. A possible alternative is the VSDS that...
