NSTEADY aerodynamics of plunging airfoils has received substantial interest for its
numerous applications, which includes helicopters blades [1], micro air vehicles [2] and …

In the near-stall regime, the shedding of coherent structures can result in large unsteady
aerodynamic loads. Under such conditions, high-aspect-ratio wings will experience some …

Recent aircraft, especially of the unmanned variety, have undergone a manufacturing shift to
light-weight composite materials. These materials allow for higher aspect ratio wings (HAR) …

An in-house-developed computational fluid dynamics code that allows for grid motion was
implicitly coupled with the differential equation for a harmonic oscillator. Simulations were …

Because of the higher aerodynamic efficiency and lighter structural weight, substantial
research studies have been conducted towards understanding the behaviors of thin, large …

The effects of structural motion on the aerodynamics of the X-56A airfoil are investigated
experimentally. An oscillatory plunging mechanism provides a sinusoidal plunging motion …

The laminar separation bubble on an X-56A wing section is studied experimentally for static
and heaving/plunging conditions at 𝛼= 12 with 𝑅𝑅𝑅𝑅= 200,000 (𝑈∞= 11 𝑚/𝑠), and …

An investigation of laminar separation bubble behavior on an oscillating X-56A wing section
has been performed experimentally at Reynolds number 200,000. Wind tunnel results along …
