STAND FOR CORROSION-STRENGTH TESTS OF GAS TURBINE ENGINE BLADE Russian patent published in 2020 - IPC G01N3/60 

FIELD: test equipment.

SUBSTANCE: invention relates to stands for investigation and testing of corrosion and strength properties of gas turbine engines blades operated at sea. Test bench for corrosion strength testing of a gas turbine engine blade comprises a gas generator connected in series on the base with a fuel supply channel, with an oxidizer supply channel and with a high-temperature gas discharge pipe communicating via a branch pipe with a test chamber, in which the test blade loading device is installed with axial force and torque, the loading device has a dynamometer for measuring the axial force and a dynamometer for measuring torque, the test chamber communicates with the downstream, after the loading device, the gas duct for exhaust of the exhaust gas, wherein in the fuel supply channel the fuel flow controller is installed, in the oxidizer supply channel the oxidizer flow regulator is installed, in the high-temperature gas discharge pipe the cooling gas supply channel is made, in the cooling gas supply channel there is a cooling gas flow rate controller, behind the cooling gas supply channel downstream there are a pressure meter and a temperature meter, in the branch pipe there is a channel for supply of brine solution into the gas flow, in which a brine solution flow controller is installed, in the test chamber, an inlet temperature sensor and an input pressure sensor are installed before the loading device, and after the loading device – an output temperature sensor and an output pressure sensor, thermocouples and resistance strain gauges installed in the tested blade loading device are fixed, external water cooling pipeline with pump and heat exchanger passes along gas generator, branch pipe, test chamber and gas duct for exhaust of waste gas.

EFFECT: broader functional capabilities of the bench.
