Aeroacoustics of a coaxial rotor in level flight [PDF]

, 2008
The aeroacoustic characteristics of a coaxial system with teetering rotors in level forward flight are compared to those of an equivalent articulated single rotor with the same solidity.

Detailed Investigation of the Eddy Current and Core Losses in Coaxial Magnetic Gears through a Two-Dimensional Analytical Model

Mathematical and Computational Applications
This work introduces a 2D model that calculates power losses in coaxial magnetic gears (CMGs). The eddy current losses of the magnets are computed analytically, whereas the core losses of the ferromagnetic segments are computed using an analytical–finite

Nonlinear control of coaxial double rotor magnetic gear based on high gain observer in wind turbine

IET Control Theory & Applications
This paper proposes a nonlinear control law with a dynamic controller based on high gain observer (HGO) for a co‐axial double rotor magnetic gear (CADRMG) based on Halbach array used in wind turbines.
