  • Developments relating to a rotor arrangement
    Patent number: 8075254
    Abstract: A rotor arrangement has a rotor-section and a circumferential moveable seal around the rotor-section. The arrangement being such that, for a given rotation rate, the rotor-section is subject to an associated radial growth and a corresponding related axial displacement, relative to the seal. The rotor-section is provided with an axially-varying profile for off-setting said radial growth of the rotor-section, adjacent the circumferential seal, at said given rotation rate.
    Type: Grant

  • Large radial movement compliant seal
    Patent number: 7438526
    Abstract: A compliant seal provides a seal between an upstream region and a downstream region. The seal includes: a seal pack carrier defining a slot, the seal pack carrier having an upstream face and a downstream face; and a seal pack slideably mounted within the slot, the seal pack having an upstream face and a downstream face. The seal pack carrier and seal pack define a high-pressure plenum which abuts the downstream side of the seal pack, and which can be pressurized to apply a force to the seal pack in the upstream direction.
