  • Patent number: 10533435
    Abstract: In a featured embodiment, a fan rotor includes a platform. Clevises extend radially inwardly of the platform. Each clevis has an aperture. A hub has hub lugs positioned intermediate spaced ends of the clevises, and apertures. A pin extends through the apertures in the hub and the clevises to connect the platform to the hub. The apertures in the clevises are formed to have an inner surface for supporting the pin. A method of forming a fan blade platform is also disclosed.

  • Patent number: 10024177
    Abstract: A fan section for a gas turbine engine includes a hub. A fan blade is secured to the hub. A platform is removably secured to the hub and is arranged adjacent to the fan blade. The platform has a body with lateral sides that each include a channel. A seal is removably received in each of the channels, with one of the seals abutting the fan blade. A method of repairing the fan blade platform includes the steps of removing a nose cone to provide access to a hub, detaching a platform from the hub, and pulling the seal from a groove in the platform.

  • Patent number: 9267386
    Abstract: A fairing assembly includes an outer wall, a first side wall, a second side wall, and a saddle. The first side wall and the second side wall extend from opposing sides of the outer wall. Together the first side wall, the second side wall, and the outer wall form a cavity within the fairing assembly. The saddle is positioned within the cavity and extends between the first side wall and the second side wall. The saddle has a first rib adapted to connect to the first side wall and a second rib adapted to connect to the second side wall. The first rib and the second rib connect together at a central hub.

  • Patent number: 8868734
    Abstract: A method, performed by a computer device, may include scanning a network of digital cross connect devices to identify an open port and determining that the identified open port has been designated as unavailable in a provisioning database. The method may further include determining that the identified open port corresponds to a recoverable port and recovering the identified open port by designating the identified open port as available in the provisioning database, in response to determining that the identified open port corresponds to a recoverable port.

  • Patent number: 6633950
    Abstract: A method and apparatus for preempting an operation in a nonvolatile writeable memory is performed using a pin. Preempting an operation is accomplished by either suspending the operation or by aborting the operation. Once an operation is suspended in the nonvolatile writeable memory, other operations can then be performed. Subsequently the suspended operation may be resumed.
