TL;DR: In this article, theoretical natural frequencies and mode shapes of the first four coupled modes of a uniform pretwisted cantilever blade and the first five coupled flexural frequencies of pre-tended tapered blading are determined by using the Reissner method.

TL;DR: In this paper, the dynamic Reissner functional in conjunction with variational calculus has been employed to derive the equations of motion of pretwisted cantilever blades of asymmetric aerofoil cross section, with the blade assumed to be mounted on a rotating disc at a stagger angle.

TL;DR: In this article, the dynamic unbalance response of a single mass Jeffcott rotor in hydrodynamic bearings is analyzed and cross-coupled spring coefficients are considered in the analysis and damping has been neglected.

TL;DR: In this article, the lateral vibrations of a uniform rotating blade have been analyzed applying the Reissner and the potential energy methods, and a convergence study of the two methods is made and the effects of shear deflection, rotary inertia, rotation and stagger angle on the blade vibration characteristics are discussed.
