Describes the collaboration and research that was developed to produce the MIT Gas Turbine Engine. Both the engine and generator are fabricated from silicon using a combination of bulk and surface microfabrication technologies. This book discusses the technical details that have gone into producing the engine and the overall systems-level.

Multi-Wafer Rotating MEMS Machines: Turbines, Generators, and Engines is an outgrowth of the MIT Micro Engine Project. This project began at the Massachusetts Institute of Technology in the Fall of 1995, and later expanded through collaborations with the Georgia Institute of Technology, the Clark Atlanta University, and the University of Maryland at College Park. The overall objective of the Micro Engine Project was to develop a small but power-dense gas turbine generator based on MEMS fabrication technologies. Thus, the project sought to develop a fuel-burning jet engine that would drive an electric generator to produce electric power for general purpose use.  Along the way, the project would advance the science and engineering of many disciplines from the MEMS perspective.The Micro Engine Project was by its very nature a highly mult-disciplinary project pursuing advances in materials, structures, fabrication, combustion, heat transfer, turbomachinery, bearings and electromechanics, all at the MEMS scale.  Many of these topics are addressed in this volume, including:materials structures and packagingmulti-wafer MEMS fabrication and and bonding technologiesElectroplating magnetic componentselectroplating magnetic structures into siliconvery-high-speed air bearingsthermofluids and turbomachineryelectric and magnetic generatorscombustion About The MEMs Reference Shelf:"The MEMs Reference Shelf is a series devoted to Micro-Electro-Mechanical Systems (MEMs) which combine mechanical, electrical, optical, or fluidic elements on a common microfabricated substrate to create sensors, actuators, and microsystems. The series, authored by leading MEMs practitioners, strives to provide a framework where basic principles, known methodologies and new applications are integratedin a coherent and consistent manner."STEPHEN D.

Unlike books currently on the market, this book attempts to satisfy two goals: combine circuits and electronics into a single, unified treatment, and establish a strong connection with the contemporary world of digital systems. It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction,'' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems.+Balances circuits theory with practical digital electronics applications.+Illustrates concepts with real devices.+Supports the popular circuits and electronics course on the MIT OpenCourse Ware from which professionals worldwide study this new approach.+Written by two educators well known for their innovative teaching and research and their collaboration with industry.+Focuses on contemporary MOS technology.
