Wind turbine of cross-flow type with constant or cyclically adjustable blade angle. The vanes (2) consist of one or more sets of blades with arched or, in sections, straight extension in longitudinal direction, comprising several substantially parallelly extending blades (3, 4 8), the spacing of which from one another is fixed by means of a number of spacing elements (5, 9) having aerodynamic profiling and providing a spacing of the order of magnitude of between 1/2 and 3 times the blade chord.
