Redesign of an upwind rotor for a downwind configuration: design changes and cost evaluation [PDF]
Wind Energy Science, 2021 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]
Wind Energy Science, 2021 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]
E3S Web of Conferences, 2023 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]
Wind Energy Science, 2020 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.

i-Perception, 2017 In January 2017, a large wind turbine blade was installed temporarily in a city square as a public artwork. At first sight, media photographs of the installation appeared to be fakes – the blade looks like it could not really be part of the scene.
