Abstract

A vertical axis wind turbine (1, fig.1) comprising a turbine rotor having an axis of rotation and at least one blade (2, fig.1) spaced from and mounted for rotation about the rotation axis of the turbine. The blade has at least one longitudinal surface substantially parallel to the rotation axis and for engagement, in use, with wind incident on the turbine rotor. The blade is a two part blade with a first leading blade portion 7 pivotably connected to a second trailing blade portion 8. The turbine includes pitch control means and camber control means for controlling the pitch and camber of the blade. The pitch control means is a pivot on the first leading blade portion, with the pitch pivot (24, fig.6) being guidable along a pitch path defined by a first physical pathway component 10, and the camber control means is a camber pivot (27, fig.6) on the second trailing blade portion, the camber pivot being guidable around a camber path defined by a second physical pathway component 11.

Description

technical field [0001] The invention relates to a turbine for use as a wind turbine. The invention relates to a turbomachine having a turbine rotor with an axis of rotation and comprising blades spaced from the axis of rotation of the turbine, wherein the longitudinal axes of the blades are substantially parallel to the axis of rotation of the rotor. Embodiments of the invention are particularly advantageous when used as part of a vertical axis wind turbine, although the invention is also applicable to water driven turbines such as tidal turbines. Background technique [0002] Darrieus vertical axis wind and water turbines are well known (see eg US 2011 / 0006526). This type of turbine has several known disadvantages including: low efficiency, lack of starting torque, and excessive vibration. In order to overcome some of these disadvantages, some turbine arrangements have been proposed which have a mechanism for adjusting the pitch of the turbine blades. The Darrieus turbin...
