The thesis contributions are (1) a new approach for measuring rotor shaft dynamics in full aero-engines that enables the development of engine-condition based mechanical health monitoring and maintenance technologies, and (2) an extended reduced-order modeling framework that provides new capability for preliminary design of engine rotor systems and forced-response experimental design.

IFToMM conferences have a history of success due to the various advances achieved in the field of rotor dynamics over the past three decades. These meetings have since become a leading global event, bringing together specialists from industry and academia to promote the exchange of knowledge, ideas, and information on the latest developments in the dynamics of rotating machinery. The scope of the conference is broad, including e.g. active components and vibration control, balancing, bearings, condition monitoring, dynamic analysis and stability, wind turbines and generators, electromechanical interactions in rotor dynamics and turbochargers. The proceedings are divided into four volumes. This fourth volume covers the following main topics: aero-engines; turbochargers; eolian (wind) generators; automotive rotating systems; and hydro power plants.

Presented here is a comprehensive work on the general principles that apply to every type of modern rotating machinery. This handbook addresses both the theoretical and practical issues pertaining to the design, analysis, development, production, and maintenance of high-speed rotating machinery. It is the only work available that provides engineers with the information they need to anticipate, locate, and eliminate destructive vibration. This outstanding handbook contains chapters written by recognized experts in their respective fields, providing practical information on: vibration considerations in the design of rotating machinery; analytic prediction of rotordynamic response; balancing of flexible and rigid rotors; and performance verification, diagnostics, parameter identification, and vibration monitoring in rotating machinery. Covering the general principles that apply to every type of modern rotating machinery, the handbook is packed with specific examples about a wide array of equipment, including steam turbines, electrical motors, generators, aircraft gas turbines, reciprocating engines, and centrifuges. Fredric F. Ehrich, a registered professional engineer and a member of the National Academy of Engineering received his B.S., M.E., and Sc.D. degrees in Mechanical Engineering from M.I.T. He spent the majority of his career in the design and development of aircraft gas turbines at General Electric Aircraft Engines and earlier in the Aircraft Gas Turbine Division of the Westinghouse Co. Since his retirement, he has been active in research and teaching as a senior lecturer at M.I.T. and in consulting. Dr. Ehrich is the author of over 50 published technical papers on rotordynamics and related topics, and he holds nine issued patents on aircraft gas turbine apparatus.

This is the first Structural Dynamics book focused on this indispensable aspect of liquid rocket engine design. This book begins by reviewing basic concepts in Structural Dynamics, including the free and forced response of SDOF and MDOF systems, along with some discussion of how numerical solutions are generated. The book then moves to a discussion of specific applications of these techniques in LREs, progressing from component level (turbomachinery and combustion devices), up through engine system models, and finally to integration with a launch vehicle. Clarifies specific topics including the Campbell and SAFE Diagrams for resonance identification in turbomachinery, the complications of component analysis in the pump side due to a host of complication factors such as acoustic/structure interaction, the "side-loads" fluid/structure interaction problem in overexpanded rocket nozzles, and competing methods for generation overall engine system interface loads. Includes specific examples for illustration while closing with rotordynamic analysis, dynamic data analysis, and vibroacoustics.
