  • Rotatable seal element for a rotary machine
    Patent number: 6082738
    Abstract: A rotatable seal element 38 is formed of at least two circumferentially continuous rings 48,50. The rings have decreased thickness T.sub.2, T.sub.3 in the outward direction. Various construction details are developed which effect the level of cyclic fatigue life. In one particular embodiment, the seal element has a flat surface 74 extending inwardly from the sides at the interface between the rings.
    Type: Grant
    Filed: August 27, 1999
    Date of Patent: July 4, 2000
    Assignee: United Technologies Corporation

  • Rotating seal for gas turbine engine
    Patent number: 4645424
    Abstract: The cavity between the first stage and second stage turbines of a gas turbine power plant is sealed by a rotating seal characterized by an I-beam section annular member spanning therebetween to transmit the axial load through the upper rim and the radial load through the lower rim of the annular member. A hammer head eccentrically mounted on the edge of the upper rim locks in the first stage rear side plate and a gap between the lower rim and second stage turbine pressure balances the I-section.

  • Rotor assembly having a multistage disk
    Patent number: 4310286
    Abstract: A lightweight, rotor assembly for a gas turbine engine having a critical speed characteristic well above the operating speed is disclosed. Various construction details which enhance the axial stiffness of the rotor assembly and which shield a portion of the disk from working medium gases are developed. The rotor assembly employs a frustoconical member to connect a shaft to the disk.
