摘要

确定了动力燃气涡轮发动机第一级高压涡轮工作叶片的疲劳失效特征。实验研究的对象是根据改进技术从 CM88Y 合金中获得的叶片，该合金用于燃气轮机组的批量生产。叶片在应力为 200-240 兆帕的条件下经受住了 1×107 次循环的测试。所确定的耐久极限与该类型叶片的既定使用寿命相符。

Evaluation of the Endurance Limit of Cooled Blades of Gas-Turbine Engines Made of Heat-Resistant Nickel Alloy

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.
