TURBO-MACHINE DISC LOCKING ASSEMBLY STRENGTH TEST DEVICE Russian patent published in 2020 - IPC G01N3/08 G01M13/00 

FIELD: turbines or turbomachines.

SUBSTANCE: invention relates to turbomachine building, namely, to devices for testing the strength of locking connections of turbomachine disks. Device consists of disc rim simulator with disk rim simulator installed in rim of imitator slot by imitator of blade root protruding beyond disc rim simulator side surfaces, in each of which there is at least one hole for application of tensile forces in vertical direction, located on their axes of symmetry. In the imitator of the blade shank the said hole is located above the slot of the imitator of the disk rim. In disk rim simulator there made are at least two holes for application of tensile forces in horizontal direction, located coaxially and mirror-like on both sides of slot of imitator of disc rim.

EFFECT: possibility of investigating a wide range of loading conditions of GTE disks, as well as evaluating efficiency of certain structural actions on criteria of durability and cyclic crack resistance in complex stress state.
