    摘要: A method is provided involving a gas turbine engine system (20). The method includes configuring a plug (32) within a fluid passage (24) in the gas turbine engine system (20), where the plug (32) is between first and second portions (34, 36) of the fluid passage (24). Material (28) is removed from an interior surface (30) of the fluid passage (24) in the first portion (34) of the fluid passage (24) to provide removed material (28), where the plug (32) substantially prevents the removed material (28) from entering the second portion (36) of the fluid passage (24). The removed material (28) is directed out of the fluid passage (24). The plug (32) is removed from the fluid passage (24).

    摘要: The invention relates to an oil jet (10) for a turbine engine, comprising a body (16) including a circulation pipe (18) intended for the flow of a pressurised fluid. The body (16) of the jet (10) comprises a first portion (24) and a second portion (26) between which a resiliently deformable membrane (52) is inserted, said membrane being capable of deforming between a sealing position in which it prevents the circulation of the fluid in the pipe (18) and a position in which it allows the circulation of fluid in the pipe (18). The second portion (26) includes bearing means (46) configured to exert a force on the membrane (52) positioned in the opposite direction to the circulation of fluid so as to pre-load the membrane (46) in locking position.

    摘要: A gas turbine engine (20) includes a bearing compartment (62a,62b) with a bottom (68a,68b) disposed opposite a top (70a,70b). An outlet (72a,72b) is formed in the bottom (68a,68b) of the bearing compartment (62a,62b). A seal (76a,76b) is positioned between the bottom (68a,68b) of the bearing compartment (62a,62b) and the top (70a,70b) of the bearing compartment (62a,62b). A scavenge line (66a,66b) is connected to the outlet (72a,72b). The scavenge line (66a,66b) forms a fluid trap (88a,88b) that extends in a first direction from the outlet (72a,72b) and the bottom (68a,68b) of the bearing compartment (62a,62b) and then extends in a second direction to a position disposed vertically between the bottom (68a,68b) of the bearing compartment (62a,62b) and the seal (76a,76b).
