Finite-State Airloads for Deformable Airfoils on Fixed and Rotating Wings
… the lift, drag, and all generalized forces of a deformable airfoil. Trailing-edge flap deflections are included implicitly as a special case of the general deformations. The theory allows for a thin airfoil performing small arbitrary motions with respect to a reference frame that can perform …

Unsteady Aerodynamics of Deformable Thin Airfoils
… (which is restricted to rigid airfoil motion) to deformable thin airfoils. Frequency-domain lift, pitching moment and thrust expressions are derived for an airfoil undergoing harmonic oscillations and deformation in the form of Chebychev polynomials. The results are validated against the …

Optimization of Harmonically Deforming Thin Airfoils and Membrane Wings for Optimum Thrust and Efficiency
… thrust efficiency of harmonically deforming thin airfoils and membrane wings. A frequency domain unsteady aerodynamic theory for deformable thin airfoils, with Chebychev polynomials as the basis functions is presented. Stroke-averaged thrust and thrust efficiency expressions are presented in a …
