A two-dimensional flexible airfoil with a freeplay non-linearity in pitch has been analyzed in the subsonic flow range. Structurally, the airfoil is modelled as finite beam elements and two spring elemens in pitch and plunge. A doublet lattice method is used for the two-dimensional unsteady aerodyna

A two-degree-of-freedom airfoil with a freeplay non-linearity in the pitch and plunge directions has been analyzed in the transonic and low-supersonic #ow region, where aerodynamic non-linearities also exist. The primary purpose of this study is to show aeroelastic characteristics due to freeplay st
A mathematical model for a #exible arm undergoing large planar #exural deformations, continuously rotating under the e!ect of a hub torque and supported by a #exible base is developed. The position of a typical material point along the span of the arm is described using the inertial reference frame
