An analytical frequency‐domain model of aerodynamic mass and damping of floating wind turbines
Wind Energy, 2023 The fore‐aft motion of the rotor‐nacelle assembly (RNA) of a rotating floating wind turbine (FWT) can cause an oscillation in aerodynamic thrust, which may be equivalently treated as frequency‐dependent aerodynamic mass and damping effects. In this study,

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 The aerodynamic characteristics of reaction stages of a large steam turbine have been studied for the basis of performance improvement. For the first step, the characteristics of a single reaction stage with typical reaction blading were studied by two-dimensional low-speed cascade tests and single-stage air turbine tests.
