Improvement of counter rotating turbine blade

摘要

（f）fixedImprovement of counter rotating turbine bladeThe counter rotating impeller (c) of the turbomachinery (10) comprises an inner rotor, an outer rotor (including an outer drum (50) and a downstream movable impeller (including a plurality of movable blades (600)), each blade (600) includes at least one downstream movable blade and extends between the outer drum and the inner disk (25), The radial inner end of the blade (600) is fixed on the inner disc (25) through bolt connection, and the radial outer end of the blade (600) is installed on the outer drum (50b) through axial locking devices (71, 72),The radial outer end of the auger (600) includes a first extended opening (622) configured to receive axial blocking devices (71, 72),The first extension opening 622 and the axial stop devices 71, 72 are configured to limit the radial outer end displacement in the axial direction and allow the radial outer end displacement in the radial direction.Abstract figure: Figure 4.
