TURBOMACHINE ELEMENT COMPRISING AUXILIARY SEALING MEANS AND METHOD FOR TESTING THIS ELEMENT Russian patent published in 2019 - IPC F02C7/28 F01D25/18 

FIELD: engines and pumps.

SUBSTANCE: object of the invention is an element of a gas turbine engine comprising stator (2), rotor (1) and first sealing means (9) between rotor (1) and stator (2) designed to be active when the rotor is in the operating position around its axis of rotation (LL). Also the element contains auxiliary pressure sealing means (20, 22) between rotor (1) and stator (2). Moreover, both sealing means are active when rotor (1) is installed along its axis of rotation (LL) during the installation operation in the test position, and rotor (1) and stator (2) form in this test position enclosure (8) between the two sealing means. Also presented are a gas turbine engine and a method for testing first sealing means (9) in the gas turbine engine component.

EFFECT: invention is intended to offer a simple means of controlling the operation of a segmented radial gasket when the rotor is installed in the crankcase; construction of an enclosure around the guide bearing, which is compact in the axial direction and at the same time protects the gaskets from oil spills.
