CONTACT RADIAL-END SEAL OF GAS TURBINE ENGINE COMPRESSOR SUPPORT Russian patent published in 2024 - IPC F16J15/30 F04D29/08 

FIELD: aircraft engine building.

SUBSTANCE: invention relates to seals of oil cavities of gas turbine engines and power plants. In a contact radial-end seal of a gas turbine engine compressor support, comprising a housing, in which there is a sealing ring in the form of graphite segments, which squeezes the rotor of the gas turbine engine by means of a bracelet spring and is fixed against turning by means of at least one locking element. At least one blind hole is made on the inner side of the end wall of the housing, wherein the locking element is installed in the sealing ring in the form of graphite segments and contacts with it with a section of its inner surface, and the outer surface of the locking element is in contact with the bracelet spring, note here that locking element end section is fitted in said blind hole with radial clearance.

EFFECT: no need to flare the locking element and re-lapping the surface of the seal housing, simplified grinding process due to absence of locking element rigidly fixed in the housing, increased tightness of the seal due to absence of through holes in its housing.
