    摘要: A system controls net thrust of a steam turbine having a stepped rotating shaft. A first leak off line fluidly couples a first stage of a turbine section to a packing near a stepped portion on the rotating shaft. A second leak off line fluidly couples a second stage of the turbine section that has a pressure different from the first stage to a step area immediately adjacent to the stepped portion, and a connection line fluidly couples the first leak off line to the second leak off line. The lines include control valves such that a controller can actively control the net thrust by regulating thrust pressure on the stepped portion using steam from the first and second stages of the turbine section. The controller may also prevent damage to an active retractable seal using the control valves.

    摘要: A bearing assembly for a gas turbine engine rotor (40) includes, an inner race (56), an outer race assembly (54), and a rolling element (52). The outer race assembly (54) includes a body, a plurality of first springs (104) attached to the body, and a plurality of second springs (106). Each first spring is radially aligned with a corresponding second spring forming a spring pair (120). The outer race assembly also includes a plurality of connecting members (108). Each connecting member extends between and connects a first end (112) of the first spring and a first end (122) of the second spring of said spring pair. The outer race assembly further includes a flange (126) with each second spring attached to the flange.

    摘要: An assembly (60) for a gas turbine engine (20) comprising a component (66) that has a first interface portion (74), and a support (68) that has a mounting portion (76) and a second interface portion (78), the mounting portion (76) attachable to an engine static structure (36), a first retention feature (80) that releasably secures the first interface portion (74) to the support (68) in a first installed position of the gas turbine engine component (66), and a second retention feature (82) dimensioned to secure the first interface portion (74) to the second interface portion (78) in a second installed position of the gas turbine engine component (66). The first installed position differs from the second installed position, and one of first and second retention features is dimensioned to carry the gas turbine engine component (66) in response to release of another one of the first and second retention features.
