DEVICE LOCKING RING SEAL ON TURBINE DISK OF GAS TURBINE ENGINE, RING SEAL OF BLADES COOLING CIRCUIT, TURBINE MODULE OF GAS TURBINE ENGINE AND GAS TURBINE ENGINE Russian patent published in 2015 - IPC F01D5/30 

FIELD: machine building.

SUBSTANCE: device locking ring seal on turbine disk comprises ring clamp, lock device and contraction device. The ring clamp is secured on the rear as per flow surface of the disk, is oriented in radial direction and limits together with the disk surface the groove, in which the ring seal is installed. The ring clamp contains cut-outs at its edge arranged at the opposite side relatively to the bottom part of the groove, for cams axial inserting in the groove, the cams are located along circle of the ring seals. The lock device is installed in the groove between the disk surface and ring seal. The contraction device is made with possibility of resting against the disk surface and interaction with lock device to lock the ring seal against the ring clamp. Other inventions of the group relate to the options of the turbine disk and ring seal in the said lock device of the ring seal on the turbine disk, and to the turbine module of the gas turbine engine containing such turbine disk, and to gas turbine engine containing such turbine module.

EFFECT: group of inventions simplifies installation of the lock device on the turbine disk.
