This book offers a general overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. A particular focus is the technique of velocity field representation and modeling via source and vorticity fields and via their sheet, filament, or point-singularity idealizations. These models provide an intuitive feel for aerodynamic flow-field behavior and are the basis of aerodynamic force analysis, drag decomposition, flow interference estimation, and other important applications. The models are applied to both low speed and high speed flows. Viscous flows are also covered, with a focus on understanding boundary layer behavior and its influence on aerodynamic flows. The book covers some topics in depth while offering introductions and summaries of others. Computational methods are indispensable for the practicing aerodynamicist, and the book covers several computational methods in detail, with a focus on vortex lattice and panel methods. The goal is to improve understanding of the physical models that underlie such methods. The book also covers the aerodynamic models that describe the forces and moments on maneuvering aircraft, and provides a good introduction to the concepts and methods used in flight dynamics. It also offers an introduction to unsteady flows and to the subject of wind tunnel measurements. The book is based on the MIT graduate-level course "Flight Vehicle Aerodynamics" and has been developed for use not only in conventional classrooms but also in a massive open online course (or MOOC) offered on the pioneering MOOC platform edX. It will also serve as a valuable reference for professionals in the field. The text assumes that the reader is well versed in basic physics and vector calculus, has had some exposure to basic fluid dynamics and aerodynamics, and is somewhat familiar with aerodynamics and aeronautics terminology.

Introduction to Ultrasonic Motors Clarendon Press

Książki / Literatura obcojęzyczna

The ultrasonic motor, invented in 1980, utilizes the piezoelectric effect in the ultrasonic frequency range to provide the motive force. (In conventional electric motors the motive force is electromagnetic). The result is a motor with unusually good low-speed high-torque and power-to-weight characteristics. It has already found applications in camera autofocus mechanisms, medical equipment subject to high magnetic fields, and motorized car accessories. Its applications will increase as designers become more familiar with its unique characteristics. This book is the result of a collaboration between the inventor and an expert in conventional electric motors: the result is an introduction to the general theory presented in a way that links it to conventional motor theory. It will be invaluable both to motor designers and to those who design with and use electric motors as an introduction to this important new invention.

Wireless CMOS Frequency Synthesizer Design Springer, Berlin

Książki / Literatura obcojęzyczna

The recent boom in the mobile telecommunication market has captured the interest of electronic and communication companies worldwide. In order to cut costs, and to decrease volume and power consumption, research is ongoing which focuses on the integration of a complete RF transceiver on a single die. This book discusses for the first time an important building block in such a single-chip wireless transceiver, that is, the frequency synthesizer. CMOS Wireless Frequency Synthesizer Design starts off with a comprehensive overview of possible synthesizer architectures together with a discussion of the general PLL theory. It goes on to present an easy calculation method of predicting LC-tuned VCO phase noise. Practical designs are presented which illustrate in detail the implementation of monolithic LC-tuned VCOs, using either bonding-wire inductors or hollow planar inductors. It is demonstrated that such designs can achieve the required phase noise specifications using standard CMOS technology. CMOS Wireless Frequency Synthesizer Design also discusses the other PLL building blocks such as the high-speed frequency divider. The phase-switching multi-modulus prescaler architecture, which combines high input frequencies with a programmable division factor, is presented in chapter 6. A concluding chapter combines all the gathered knowledge and presents the first monolithic standard CMOS frequency synthesizer that achieves the DCS-1800 specifications. CMOS Wireless Frequency Synthesizer Design is essential reading for all researchers and practicing engineers working in the design of wireless communication systems requiring highly integrated RF transceivers and frequency synthesizers.
