On the stability of rotating blade arrays
Journal of Sound and Vibration, 2004Abstract A mathematical model consisting of an array of rotating pendulums was built to study the stability of an array of rotating blades and the dynamic interaction between the blades and the rotor. This model can be solved in closed form, yielding some general results regarding the stability of the system, particularly for the effects of the blade–

Non-linear flapping vibrations of rotating blades
Journal of Sound and Vibration, 1982Summary: The nonlinear equations of motion of a rotating blade undergoing extensional and flapwise bending vibrations are derived, including nonlinearities up to 0(e3). The strain-displacement relationship derived is compared with expressions derived by earlier investigators and the errors and the approximations made in some of those are brought out ...

Dynamic Response of a Rotating Blade with Time-Dependent Rotating Speed
Journal of Sound and Vibration, 1993Abstract The general vibration of a rotating blade with time-dependent angular speed is investigated in this paper. A simple plate model is used to represent the blade, and its angular speed is characterized as a small periodic perturbation superimposed on a constant speed.

This paper deals with the deformation and the stress of an axial flow compressor rotor blade under the loading of centrifugal forces. Coupled deformation of extension, bending, torsion and transverse shear of a pretwisted curved bar with arbitrary cross section is considered.

Proceedings of the Symposium on Status of Testing and Modeling Techniques for V/STOL Aircraft, Philadelphia 1972, 1972
An experimental investigation has been made in the Langley full-scale tunnel and outdoors to investigate some of the characteristics of vortex noise generated on a rotating-blade system. Acoustic measurements were made at several microphone positions for two different blade sections with several tip shapes and spoiler configurations.
