Abstract

Abstract

The design and optimization of gas turbine blades for high-temperature operations are critical to enhancing the efficiency and reliability of power generation and propulsion systems. These components operate under extreme conditions of heat, pressure, and mechanical stress, making their performance pivotal to the overall effectiveness of turbines. This study explores the key factors influencing blade performance, emphasizing the importance of material selection, thermal barrier coatings, aerodynamic design, cooling mechanisms, and structural optimization. Nickel-based superalloys and advanced composites are highlighted for their remarkable thermal and mechanical properties, enabling them to withstand high operational temperatures and stresses. Additionally, the application of thermal barrier coatings, such as yttria-stabilized zirconia (YSZ), provides essential protection against extreme heat, thereby improving blade longevity. To enhance aerodynamic performance and reduce energy losses, computational fluid dynamics (CFD) techniques are employed to refine blade profiles and improve airflow characteristics. Finite element analysis (FEA) further supports the design process by evaluating stress distribution and structural integrity under operational conditions. Innovations in cooling techniques, such as advanced film cooling and additive manufacturing, are also discussed for their role in improving heat dissipation and maintaining blade durability. The challenges of developing ultra-high-temperature materials, coupled with the integration of predictive monitoring systems, are critical areas of focus. Future directions include bio-inspired cooling designs and the application of artificial intelligence-driven optimization methods. This comprehensive approach aims to address existing challenges while pushing the boundaries of turbine blade technology, ultimately contributing to more sustainable and efficient energy solutions. By integrating advanced materials, cutting-edge technologies, and innovative design practices, the field continues to evolve toward achieving higher efficiency and operational reliability.
