Indagationes Mathematicae, 2016 We present and analyse a simple model for the twisting somersault. The model is a rigid body with a rotor attached which can be switched on and off. This makes it simple enough to devise explicit analytical formulas whilst still maintaining sufficient complexity to preserve the shape-changing dynamics essential for twisting somersaults in springboard ...

Investigation of Rotor-Rotor and Rotor-Structure Interactions on Multi-Rotor Wind Turbine Systems
Journal of Physics: Conference SeriesAbstract Multi-rotor wind turbine systems (MRS) are an innovative alternative to conventional single-rotor (SR) wind turbines. This paper investigates the rotor interactions of three 20 MW floating offshore MRS designs with 12, 27 and 48 rotors respectively.

THE ROTOR MODEL AND COMBINATORICS [PDF]
International Journal of Modern Physics B, 2002 We examine the groundstate wavefunction of the rotor model for different boundary conditions. Three conjectures are made on the appearance of numbers enumerating alternating sign matrices. In addition to those occurring in the O (n = 1) model we find the number A V (2m + 1;3), which 3-enumerates vertically symmetric alternating sign matrices.

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

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub
International Journal of Rotating Machinery, 2000 The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...
