The performance of a three straight bladed Cross-Flow or Vertical Axis Turbine based on symmetrical profiles, with a chord-to-diameter ratio of 0.16 has been studied in detail. The research is focused on the effects of Reynolds number and blade pitch angle, not only in the performance itself, but in the appearance or not of a dead band region in which aerodynamic loading cannot overcome resistive loads. Experiments were carefully designed in order to cover the transitional region were this dead band is incipient, for Reynolds numbers in the range from 3 to 5.10(5). Results show how the performance is highly dependent on pitch angle at all Reynolds numbers investigated. Efficiencies over 25% are reached at tip speed ratios (blade to free stream velocity ratio) slightly larger than 2, for pitch angles in the range 4-8 degrees. The appearance of the dead band is conditioned by the combination of Reynolds number and pitch angle.
