Rotor blade design for a wells turbine

摘要

The invention relates to a Wells turbine comprising a hub with a plurality of rotor blades having a symmetric profile in the form of a teardrop starting from a leading edge; the rotor blades have a connection line the extension of which in the rotation plane of the Wells turbine deviates at least in parts of the radial extension of the rotor blade from the radial distance associated with the corresponding rotor blade, the connection line having at least one curved portion.
