Bladed turbine, pump or wind rotor - has rotor blades rotating at half rotor speed about axes parallel to central rotor axis

摘要

The bladed rotor assembly comprises a number of blades (1) which rotate about their own central axes whilst they move around the central rotor shaft parallel to the blade axes. The angular velocity of the blades is half that of the angular rotor velocity. This may be achieved by coupling each blade to a fixed central gear wheel (3) via a gear wheel (2) carrying the blade. The phase angle relative to the fluid flow direction may be adjustable by rotation of the gear (3).
