In this paper a new method based on blade element theory is described, aiming at the calculation of the characteristics of a wind rotor and the analysis of its aerodynamic behaviour. The new method ...

The performance of a three bladed 3.3 m diameter turbine was measured unobtrusively in a large scale, controlled wind, open jet facility. Due to the scale of the facility blockage was very low in ...
