The Transient Aeroelastic Response of Rotor Systems in Axial Flight.
Abstract
The theorems of variational mechanics are employed to derive the equations of transient motion of a helicopter rotor in axial flight. Bending, torsion, and flapping motions are permitted. The resulting equations are solved approximately by means of a modified Galerkin technique and yield frequencies and damping ratios for given rotor parameters and a given rotor angular velocity. Aparametric study of the variables is made and the results are discussed with particular reference to the damping ratios dependence on the rotor parameters. (Author)
