Redesign of an upwind rotor for a downwind configuration: design changes and cost evaluation [PDF]
Within this work, an existing model of a Suzlon S111 2.1 MW turbine is used to estimate potential cost savings when the conventional upwind rotor concept is changed into a downwind rotor concept. A design framework is used to get realistic design updates

A method for preliminary rotor design – Part 1: Radially Independent Actuator Disc model [PDF]
We present an analytical model for assessing the aerodynamic performance of a wind turbine rotor through a different parametrization of the classical blade element momentum (BEM) model.

Longitudinal and transverse oscillations of the impact device tool under impulsive loads [PDF]
The destruction process of the rock by the tool of the impact device occurs with an impulsive load on the tool from the recoil reaction from the side of the rock, not only in the axial, but also in the transverse direction.

Optimal relationship between power and design-driving loads for wind turbine rotors using 1-D models [PDF]
We investigate the optimal relationship between the aerodynamic power, thrust loading and size of a wind turbine rotor when its design is constrained by a static aerodynamic load.
