Natural Frequency of Rotor with Rotor Core.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 A rotor core of induction motors consists of many multilayered steel sheets for core which are fixed to a shaft with a shrinkage fit. A bending vibration of rotors with such a rotor core is investigated experimentally. It is shown that the rotor can be modelized by an opening of the multilayered steel sheets and a equivalent Young's modulus of the ...

Architecture of the flagellar rotor [PDF]
The EMBO Journal, 2011 Rotation and switching of the bacterial flagellum depends on a large rotor-mounted protein assembly composed of the proteins FliG, FliM and FliN, with FliG most directly involved in rotation. The crystal structure of a complex between the central domains of FliG and FliM, in conjunction with several biochemical and molecular-genetic experiments ...

Rotor wake interactions with an obstacle on the ground [PDF]
, 2018 An investigation of the flow around an obstacle positioned within the wake of a rotor is described. A flow visualisation survey was performed using a smoke wand and particle image velocimetry, and surface pressure measurements on the obstacle were taken.

Main rotor-tail rotor intraction and its implications for helicopter directional control [PDF]
, 2008 Aerodynamic interference between the main and tail rotor can have a strong negative influence on the flight mechanics of a conventional helicopter. Significant unsteadiness in the tail rotor loading is encountered under certain flight conditions, but the

Dynamics of Anisotropically Supported Rotors
International Journal of Rotating Machinery, 1997 The paper discusses dynamic effects occurring in machinery rotors supported in bearings and pedestals with laterally different characteristics. In the considered rotor model the anisotropy of radial stiffness and tangential (“cross”) stiffness components

Simulation of the Aerodynamic Interaction between Rotor and Ground Obstacle Using Vortex Method [PDF]
, 2018 The mutual aerodynamic interaction between rotor wake and surrounding obstacles is complex, and generates high compensatory workload for pilots, degradation of the handling qualities, and performance, and unsteady force on the structure of the obstacles.
