Structural Dynamics of Liquid Rocket Engines

Focusing on the crucial role of structural dynamics in liquid rocket engine design, Structural Dynamics of Liquid Rocket Engines offers both foundational knowledge and practical applications.

The book Structural Dynamics of Liquid Rocket Engines serves as a comprehensive resource dedicated to the essential aspects of designing liquid rocket engines (LREs) through the lens of structural dynamics. It begins with a thorough review of fundamental concepts in structural dynamics, focusing on the free and forced responses of single-degree-of-freedom (SDOF) and multiple-degree-of-freedom (MDOF) systems. The initial chapters also delve into the methods used for generating numerical solutions, laying a solid foundation for the applications that follow.

As Structural Dynamics of Liquid Rocket Engines progresses, it transitions into specialized applications of structural dynamics techniques within the context of LREs. The book explores these applications at various levels, starting from individual components like turbomachinery and combustion devices. It then advances to engine system models and ultimately addresses the integration of these systems with launch vehicles. This structured approach ensures readers gain a comprehensive understanding of how structural dynamics principles apply at each stage of engine design.

The text also clarifies several critical topics, including the use of Campbell and SAFE diagrams for identifying resonance in turbomachinery. It discusses the complexities of component analysis, particularly on the pump side, where factors such as acoustic/structure interaction come into play. Additionally, the book tackles the challenges of fluid/structure interactions in overexpanded rocket nozzles and presents various methods for generating overall engine system interface loads. With practical examples and concluding discussions on rotordynamic analysis, dynamic data analysis, and vibroacoustics, this book is an invaluable resource for engineers and researchers in the field.
