STRAIGHTENING APPARATUS OF COMPRESSOR OF GAS TURBINE ENGINE Russian patent published in 2021 - IPC F04D29/54 F01D9/04 

FIELD: engines.

SUBSTANCE: in the straightening apparatus of a compressor of a gas turbine engine, containing blades installed in the body of the compressor, an inner ring made disassemblable and conical relative to the longitudinal axis of the gas turbine engine wherein slots are made around the circumference wherein the blade shanks are installed, a sealing ring made disassemblable and integral with the inner ring forming an annular cavity therebetween, according to the present invention, transverse slots are made in blade sections located in the annular cavity, wherein an elastic annular element made disassemblable is installed, wherein elastic spacer elements are installed between the blades in the gaps between the inner ring and the elastic annular element, with contact along adjoining surfaces thereof, wherein axial protrusions are made on the side of the lateral surface of each of the elastic spacer elements facing the turbine of a gas turbine engine, the end sections whereof extend beyond the annular cavity through the through holes made in the lateral wall thereof, wherein the radial size of each of the through holes is greater than or equal to the maximum radial size of an elastic spacer element, radial protrusions are also made on the axial protrusions of the elastic spacer elements, the ends whereof are in contact with the inner surface of the lateral wall of the annular cavity.

EFFECT: increased repairability and manufacturability of the straightening apparatus, as well as increased reliability of operation thereof are achieved by adjusting the stiffness characteristics in the process of engine development.
