Understanding Gas Turbine Engine Design and Material Failures in Aircraft

In this insightful lecture, Teresa Pollock, a Materials Science Professor at UCSB, delves into gas turbine engine design and the critical role materials play in aircraft flight safety. She explains the engine's four main sections—fan, compressor, combustor, and turbine—and discusses the complexities of material selection, particularly in ensuring high performance under extreme conditions. Pollock highlights a notable case of turbine disk failure, emphasizing the need for understanding material defects and the importance of using single crystal components for enhanced durability. This comprehensive overview explores the intersection of engineering, science, and safety, offering viewers valuable insights into the innovations driving modern aerospace technology.
