  • Shaft assembly comprising a frangible coupling and a flexible coupling
    Patent number: 10344806
    Abstract: A shaft assembly comprises a first shaft portion, connected to a second shaft portion by a flexible coupling. The first shaft portion is further connected to the second shaft portion by a frangible coupling with the frangible coupling being configured to fail if a torsional load through the frangible coupling exceeds a predetermined maximum torsional load. The flexible coupling allows an angular misalignment between the first and second shaft portions not exceeding a maximum angular misalignment.
    Type: Grant

  • Developments in or relating to rotor balancing
    Patent number: 9624775
    Abstract: A method of reducing dynamic imbalance in a bladed rotor assembly by axially adjusting one or more of the blades so as to redistribute mass along the geometric axis of the assembly. The blades may be axially adjusted to form a counterbalancing couple. Additional correction masses may be added for supplemental correction of couple imbalance or residual static imbalance in the bladed rotor assembly. The invention offers a reduction in the weight penalty associated with conventional balancing corrections carried out on the bladed rotor assembly.
