“…In Sabour's dissertation [25], a novel mathematical model for predicting the operational life of aircraft components (particularly gas turbine blades susceptible to creep-fatigue at elevated temperatures) was proposed, and its numerical and experimental evaluation was conducted. The Lagrange-Bhat method In 1993, Vetrov and Kucher [28] conducted a creep analysis to determine the remaining lifespan of blades. Their methodology involved considering the accumulated creep strain and accounting for the impact of vibration loads.…”

The aircraft is subjected to high-temperature and high-pressure conditions during flight, which renders it susceptible to the occurrence of creep phenomenon. Several academics have conducted extensive research on this issue. This research paper provides a comprehensive overview of the existing literature on creep phenomena in aircraft engines. First, several classical creep calculation models are enumerated and categorized as creep life calculation, creep-fatigue life calculation, and creep deformation calculation. Studies on creep phenomena are conducted in various components of aircraft engines, such as the engine’s turbine blades, turbine disks, and combustion chambers. The creep behavior of turbine blades in aircraft engines has been extensively researched. Furthermore, the protective measures aimed at mitigating creep are presented. Materials with high creep resistance can be used, and alternative fuels could be implemented. This paper provides an in-depth analysis of the advantages of creep in aircraft, presented in a favorable perspective. Finally, the prospective future research direction is discussed.
