Wing for wind turbine to reduce deflection and flap-wise moment, has predetermined mass concentrations distributed in the wing tip or its vicinity for straightening the wing by its rotation

摘要

The wing (3) is for a wind turbine which has one or more wings mounted in a rotor and is characterised in that the wing is provided with a certain rigidity in flap-wise direction, and with a predetermined mass distribution in the wing for straightening of the wing by its rotation, as the wing is provided with one or more mass concentrations (4) in the wing tip or in its vicinity. The wing is provided with mass concentrations in the outermost 2/3rds of the wing and comprises of embedded sand, lead or similar material having a high mass density.
