Abstract

The characteristics of fatigue failure of the working blades of the first stage of the high-pressure turbine of the power gas-turbine engine were determined. Experimental studies were carried out on blades obtained according to the improved technology from the CM88Y alloy, which is used in the serial production of gas-turbine units. The blades withstood the test base of 1×10⁷ cycles at a stress of 200–240 MPa. The established endurance limit corresponded to the given service life of blades of this type.
